04 | 05 Product overview Vogelsang: simply more biogas Reliable components for individual tasks Within the scope of the transition toward alternative energy sources, biogas plants now constitute a reliable pillar of gas and energy production in Germany as well as other countries worldwide. Their reliability and efficiency depend on the quality of the technology installed in the biogas plants – regardless of whether they are small biogas plants on farms or larger ones geared toward energy production. Vogelsang has stood by the pioneers of biogas technology from the very beginning and continues to support efficient and economical operation of their systems today. Our knowledge advantage The biogas plant components we develop and continually perfect have stood the test in applications all over the world. Research, continuous further development and innovative features help plant operators to maximize their gas yield. Efficient biogas production The cost-effectiveness of a biogas plant depends primarily on the efficiency of the individual components. Each and every one of our components contributes to that aim, thanks to the choice of high-quality materials and clever ways they work. The intelligent coupling of individual machines that are perfectly coordinated to work harmoniously with one another opens up even more opportunities for cost-effective biogas production. A worthwhile investment Vogelsang offers reliable products and efficient solutions tailored to your individual task requirements. The same goes for pumping, cutting and digester feeding technologies as well as the separation and disintegration of substrates: The more consistent the processes and more homogeneous the organic suspension fed into the digester, the higher the gas yield. This even reduces the energy costs for pumping and mixing the suspension, which in turn positively affects the overall balance sheet.* Quality management At Vogelsang, quality control is a self-evident necessity. None of our products leave the factory without being thoroughly checked first. We are constantly taking our quality management system to the next level, and regularly earn certification in accordance with DIN EN ISO 9001:2015 – after all, those who fail to improve will surely be left behind. By the way: We also offer progressive, highly functional solid matter feeders for digester feeding that supports optimal bacterial culture development. Technology that helps operators to reduce the energy requirements of their biogas plant for mashing, stirring and pumping – while improving the gas yield at the same time. For more information, see Vogelsang’s brochure on “Innovative Solid Matter Feeding.” * Source: Results from an EU research project known as EU AGRO BIOGAS demonstrate cost reductions of up to 40 % and gas yield improvements of up to 8 %, relative to operation of a 500 kW biogas plant.

08 | 09 Progressive cavity pumps | HiCone Optimally tuned for long service life The interplay of unique geometry and an innovative adjustment system saves energy and extends the service life of the new HiCone® progressive cavity pump HiCone Automatik: adjustment during ongoing operation After years of being out of the spotlight, biogas has finally come back into focus as a sustainable and flexible energy source. The challenge: developing an efficient technique that enables lower prices for production and supply. As the inventor of the elastomer-coated rotary lobe pump, the RotaCut wet cutter with integrated heavy material separator, and many other groundbreaking machines and devices for the economical production of biogas and the utilization of digestate, it‘s only natural that Vogelsang has also worked toward optimizing the operating principle of progressive cavity pumps. We have already made a decisive breakthrough that helps plant operators by implementing rapid parts replacement for pumps in the CC series. The new progressive cavity pumps of the HiCone series further- more feature a revolutionary, conical geometry and clever adjustment system, which enables longer service life than ever before while significantly reducing overall lifecycle costs. Adjustable setting with extraordinarily easy handling In order to react quickly and easily to different pumping tasks, the clamping between the rotor and stator of the pumps can be adjusted accordingly during operation. At the touch of a button or a mouse click in the control, the pump elements can be directly and precisely adjusted to operating parameters such as pressure, viscosity or temperature of. This keeps energy consumption as well as wear and tear at a minimum. Maximum availability at the lowest possible power consumption The result: a service life that is several times longer and an extremely high availability compared to conventional progressive cavity pumps. This represents a significant cost advantage, especially since the lower power consumption, which is always kept to a minimum, leads to further savings. In addition, simply starting up a HiCone series pump consumes significantly less electricity than usual. The reason for this is the intelligent automatic start-up system, which makes it possible to use smaller and therefore less expensive motors and power electronics to achieve the same result. At the same time, this start-up feature ensures energy-efficient operation, particularly with short pump cycles.

A new era The pinnacle of effi ciency: The durable HiCone® progressive cavity pump with QuickService functionality Even the proven CC series pumps had already helped to avoid long downtimes thanks to their reliability and durability. And now, Vogelsang‘s new HiCone series pumps require even less maintenance, thanks to the unique, conical geometry of the pumping elements and the associated adjustment options. Users benefi t from signifi cantly longer service life and higher availability – leaving them with more time for essential tasks. The current wear status of the pumping elements is displayed continuously. If a service call is required, it can be planned in advance. Even the pumps of the latest generation benefi t from the proven QuickService principle when it comes to parts replacement. The swiveling mechanism enables quick and easy replacement of the pumping elements, with no need to remove the pump from the pipe system. In just a few simple steps, the stator and rotor can be removed and replaced as a complete unit – including the cardan shaft, if necessary. And replacing the pre-assembled mechanical seal is just as easy: it can be replaced from the side after removing the geared motor. HiCone progressive cavity pump

12 | 13 Progressive cavity pumps | CC series Clever combination: Reliable pumping and simple parts replacement As rotating, positive displacement pumps, Vogelsang’s CavityComfort (CC series) have proven themselves especially in the biogas sector. The robust progressive cavity pumps demonstrate their durability and reliable pumping performance in applications involving highly viscous and abrasive media that may also have a high content of foreign matter. Thanks to the innovative design, CC series pumps are especially favored when long periods of downtime for service and maintenance are simply unacceptable. The principle The CC progressive cavity pumps from Vogelsang combine a helical rotor with a stator surrounding the rotor, which also has a helical mount. Because of their geometry and the eccentric rotation of the rotor, cavities are created within the stator through which highly viscous media can be pumped. Since the pumping principle relies on sealing contact between the rotor and stator, pumping against high pressures is also possible without loss of power. QuickService: Unique concept for rapid parts replacement Our biogas customers appreciate the straightforward accessibility of pumping elements in CC series pumps. This enables parts to be replaced with speed and ease unparalleled among progressive cavity pumps – so the pump is ready for operation again in a short time. The stator and rotor to be replaced are simply replaced as a unit. The entire rotating unit (stator, rotor and Cardan shaft) can also be replaced if necessary. Alternatively, the stator can be removed after pivoting the pumping elements as unit out. Next, the rotor and/or Cardan shaft are replaced, if necessary. But however you decide to proceed, it is not necessary to remove the sleeve that protects the robust Cardan shaft. And thanks to the clever swiveling mechanism, it’s not necessary to disassemble parts of the pipe system for maintenance and repair. Practical sealing change The tried-and-trusted cartridge mechanical seal is used for the pump shaft seal. Since it is a preassembled mechanical seal, it can be quickly and easily replaced on-site – usually after removing the Cardan shaft through the pump chamber. When the parallel shaft geared motor is removed, the seal is accessible from the drive end, where it can be replaced with just a few motions – without opening the pump. Clever details ensure a long lifetime In designing the CC series, the Vogelsang developers worked to optimize many factors that affect service life. To prevent faults, for example, the Cardan shaft is generously dimensioned and is protected by a durable sleeve as standard. Sturdy parallel shaft geared motors supply the drive power. The flow-optimized StreamLine suction housing ensures extremely large free passage within the entire pump and avoids blockages. As an alternative, the MultiConnect suction housing allows multiple pipe systems of different sizes and connector forms to be easily and directly connected.

Reliable performance, flexible applications Vogelsang rotary lobe pumps – proven reliable in the widest variety of pumping tasks Pumping liquid manure or wastes and substrates from industrialized agriculture, in particular, requires sophisticated, durable and powerful pump technology. Abrasive solid and fibrous matter or especially viscous liquids set the bar high for both suction power as well as pump durability. In the worst case, clumps and large disruptive and foreign matter can result in pump failure, thereby bringing additional systems to their knees, such as solid matter feeding. We have guided them from invention to perfection. Today, elastomer-coated rotary lobe pumps set the standard worldwide for reliable and durable pump technology in many sectors. Advantages of Vogelsang pumps • Minimal space requirement thanks to compact design • Suitable for all applications with easy handling due to reversibility of pumping direction, self-priming and dry-running resistant • Resistance to foreign matter thanks to the innovative InjectionSystem • Economical operation thanks to high efficiency and pulsation-free HiFlo lobes • Easy to maintain and easy to service, high availability thanks to low downtime

16 | 17 Rotary lobe pumps | VX series Always at the forefront of technology Whether standard models or custom solutions Since Vogelsang rotary lobe pumps have proven themselves for decades in industry and agriculture, they are also used in thousands of biogas plants around the world. Thanks to continual further development and innovative features specially designed for the sector, they deliver efficient pumping and high maintainability – a decisive trump card in the hand of any economically minded operator. The principle Vogelsang rotary lobe pumps are contact-free, rotating, positive displacement pumps. Thanks to pulsation-free HiFlo rotary lobes, they deliver extremely low vibration and even pump performance. Their unique design makes the pumps resistant to both foreign matter as well as running dry. The flow rate increases in proportion to the speed, so Vogelsang rotary lobe pumps have proven themselves to be an efficient choice for virtually any type of pumping task in a biogas plant. Maximum versatility for biogas The uses of Vogelsang pumps are virtually unlimited. Vogelsang rotary lobe pumps pump a wide range of media, from digestate to abrasive media like liquid manure containing sand, through to highly viscous organic suspensions with a high content of fibrous and solid matter. Thanks to the free passage of up to 90 mm, even large pieces of matter can pass through the pump. Compact and space-saving These compact pumps can be integrated into any system – even in the most limited of spaces. Vogelsang rotary lobe pumps are also very easy to retrofit in most cases. Practical, economical and easy to maintain Vogelsang pumps are easy to operate and maintain. This ensures low downtime, high availability and, above all, low operating costs. Simply open the cover for easy access to the pump chamber thanks to the QuickService design. Wear parts can be replaced in the blink of an eye without completely removing them from the pipe and disassembling the pump. For more stability when working with high pressures, QuickService pumps are equipped with a third support bearing in the cover. Drives A selection of combustion, hydraulic and electric motors are available in different versions – driven by a geared motor or, in a more compact fashion, a belt with piggy back electric motor. All pumps can be designed so that the control functions occur via a variable frequency drive to ensure optimal operation at all times. Shaft warranty A large cross-section, no recesses – the result: Vogelsang pumps have break-resistant shafts! For this reason, we provide a five-year guarantee against internal shaft breakage* for all pumps in the VX series. * Under the normal conditions of use in accordance with our terms of warranty

Sealing technology for professionals For rapid and reliable seal replacement, cartridge mechanical seals have been the standard for years in VX series pumps. The completely preassembled units contain all components, thereby ensuring high availability and operational reliability. Special units of these 100 percent tested seals are available for biogas plants as required. Vogelsang InjectionSystem In conventional rotary lobe pumps, foreign and solid matter does not immediately enter the pump chamber, but instead rotates in front of the pump chamber. This often results in damage as well as increased wear on the lobe tips. The innovative InjectionSystem enables foreign matter to be injected directly into the opening pump chambers. This prevents collisions with the lobe tips. The internal sealing of the pump is also increased. The fl exible injection modules can be adapted on-site for a different fl ow direction. Control technology The implementation of progressive control technology realizes a signifi cant increase in the performance and effi ciency of our rotary lobe pumps. Pressure, current consumption and (optionally) speeds are monitored constantly; the correlations between them are intelligently linked. In this way, the Performance Control Unit (PCU) is able to automatically register the load and ensures that the pump is operated in the optimum range, using appropriately defi ned control interventions. Series The VX series rotary lobe pumps are available in four series. Each individual pump is confi gured according to the requirement and case of application. The interior coating, lobe material and drive type are determined individually according to the need of your biogas plant. Special designs Upon request, we can also develop special designs in-house to meet your specifi c requirements. For example: • Multi-chamber pumps • Submersible pumps • Mobile pump systems • Combination of drives • Radial wear plates • ATEX-compliant A vortex forms upstream from the inlet in rotary lobe pumps of conventional design. Foreign matter that damages the lobe tips becomes trapped here. The Vogelsang InjectionSystem prevents vortex formation. It reduces damage due to foreign matter and increases effi ciency as well as intake capacity.

With its completely novel design, the Vogelsang IQ series proves that it’s worthwhile to rethink even a technology that has been successful for years. The number of essential components in the pump chamber has been signifi cantly reduced while the basic construction has been completely redesigned. This makes both operation and maintenance even easier compared to the VX series. The principle The IQ series rotary lobe pumps are positive displacement pumps equipped with the pulsation-free HiFlo rotary lobe. Thanks to the InjectionSystem incorporated into the pump housing, they have an extremely high tolerance for foreign matter, which protects the lobes from damage and ensures consistent intake capacity. The liquid reservoir integrated as standard additionally prevents the pumps from running dry. In contrast to the VX series, the pump housing of the IQ series consists of just a single component. It can be dismounted with just a few movements, giving access to the pump elements, while the pump remains fi rmly screwed into the pipe. Simple integration The variable series connecting parts on IQ series pumps are suitable for the most common installation situations. This means that they can be quickly and easily attached or installed in a wide range of positions, including to tank vehicles and mobile units, without the need for special connectors. Long service life and low operating costs The InjectionSystem does more than increase the intake capacity and effi ciency of the pumps. The intelligent foreign matter handling increases the service life of the pump – up to 150 percent in fi eld tests. Along with the simplifi ed design, the fact that the number of central spare parts has been reduced by half compared to the conventional design helps save costs. The spare parts themselves are also less expensive and less time is required for maintenance and parts replacement: IQ series pumps are designed so that it takes less than half the time to replace all wear parts – including rotary lobes, wear plates, pump housing and seal. IQ152–158 mounted on a torsion-resistant motor base. The fl exible connection parts allow easy adaption to common installation situations. Advantages of the IQ series • Free access to pumping elements in next to no time • Intelligent foreign matter handling • Excellent suction capacity and integrated dry-running protection • Signifi cantly reduced spare parts costs

Fewer inter- ruptions and homogeneous suspensions Der RotaCut® with integrated heavy material separator – for reliable processes and low maintenance costs Trouble-free, consistently running processes are indispensable for effi cient gas production in biogas plants. When dung and grass silage are used, more metal parts, stones and other disruptive matter such as hoof chunks, branches, straw ropes and nets end up in the biogas plant. There they clog or even damage plant components all too often. At the same time, the viscosity of the organic suspension rises, especially when extremely fi brous biomass such as straw or even forage wagon grass are fed in, which rapidly results in fl oating layers in the digester. All of these impair the effi ciency of the plant and increase energy requirements for mixing. The RotaCut reliably separates heavy material, macerates coarse matter and cuts fi brous biomass. It homogenizes the organic suspension, thereby ensuring reliable and economical plant operation. Whether liquid feeding, digester circulation or transfer to the post digester, or returning recirculate; upstream of separation or upstream of the external heat exchanger – the RotaCut has versatile uses and can signifi cantly contribute to boosting the effi ciency of the biogas plant. Vogelsang uses its proprietary software to calculate the optimized geometry for every size-reduction ratio. For you this means: You always get the best geometry for smooth running, with minimal wear. The cutting screens are produced from wear-resistant special steel and are reversible. RotaCut® advantages • Reliable cutting of fi brous and coarse matter • Foreign matter protection for all downstream components • Mixer and pump power requirements are lower thanks to more homogeneous and fl owable suspensions • Increased substrate surface area, which means higher gas yield • Fully automatic, interruption-free and low-maintenance operation thanks to Automatic Cut Control (ACC) • Fully automatic monitoring of the unit as well as automatic fault elimination with PCU (optional)

22 | 23 RotaCut The principle The RotaCut is a macerator for more or less viscous media that combines two functions: heavy matter separation and solids reduction. It processes solid matter content into easily pumpable media. While the medium continually fl ows through the RotaCut, heavy material such as stones or metal parts are separated out by gravity. They are easily removed later through a cleaning port. All fl oating and suspended substances within the medium (fi bers, hair, bones, wood, entangled material, whole plant silage or grass) are transported to the cutting screen by the liquid current and macerated by rotating, self-sharpening cutting blades. The medium is homogenized at the same time. ACC: Constant power, long service life Automatic Cut Control (ACC) consistently ensures excellent cutting performance by the RotaCut. There’s no need for manual maintenance as the ACC automatically adjusts the cutting blades of the RotaCut and keeps the necessary contact pressure constant – as high as necessary and as low as possible. This means the pressure can be adapted to the medium at any time without interrupting operation. This not only reduces power consumption requirements, it also reduces wear and signifi cantly extends the lifetime of the cutting blades. Always informed with ACC plus The optional ACC plus feature enables online monitoring of the RotaCut for the RCQ and RCX series. An external display and/or the control graphically indicates the status of the cutting blades and informs you when the blades require changing, so you can plan spare part orders and maintenance well in advance. ACC systems are therefore the foundation of effi ciency gains and the greatest degree of automation for continuous use applications. Performance Control Unit (PCU): Effi ciency through intelligent control technology If multiple pumps and cutters are grouped together into one unit, the PCU checks processes in each machine, as well as other parameters. It ensures optimum communication between the machines and continuously monitors the loads of the individual units. Individual components are controlled so as to ensure that the unit as a whole achieves optimum results. The PCU detects faults early on and rectifi es them before they pose a problem – fully automatically. All the parameters can be transferred via a Profi bus connection to the central control for remote monitoring. When the operating parameters are controlled fully automatically and based on the given situation, operators benefi t from minimized faults, a longer lifetime and reduced costs. Remove foreign matter more quickly with the Debris Removal System Depending on the choice of substrates, large quantities of foreign matter end up in biogas plants. Removal has generally required considerable effort, which is why it’s well worthwhile to supplement the RotaCut RCX with the innovative Debris Removal System (DRS) from Vogelsang. The foreign matter separated out by the RotaCut is removed during ongoing operation – with no need to switch off or open the RotaCut RCX. Compared to conventional solutions, the DRS makes it possible to do so in just one-sixth of the time – and can even be partially automated using an appropriate control. Moreover, only approx. 15 l of medium is removed along with the heavy material. This both prevents extended downtime of the RotaCut RCX and means that there is only a small quantity of medium to return to the system. RCQ-33G Inline RC 10000 Compact XL RCX-58G with DRS

26 | 27 CC-Cut and BioCut Economical pumping thanks to two compact pump systems In most biogas plants, it’s necessary to prime, pump and prepare highly diverse liquid media. They usually contain a great deal of solids and fibrous matter, as well as disruptive matter like branches, hoof clumps, etc. – that are highly viscous and loaded with many foreign matter. Vogelsang has developed two compact pump systems especially for these kinds of demanding pumping tasks: BioCut and CC-Cut. Both comprise a robust positive displacement pump with a powerful upstream cutter. The principle While the BioCut is equipped with a self-priming rotary lobe pump, the CC-Cut pumps the media fed in using a progressive cavity pump. Both include an integrated, specialized model of the proven RotaCut, giving the entire unit extremely compact dimensions. With low space requirement, the machines act as the central pump system, ensuring that heavy material like stones and metal parts are reliably separated from liquid manure, organic suspensions or other liquids. At the same time, they macerate the disruptive matter contained in the medium as well as the biomass intentionally fed into it, and homogenize the suspension for smooth and uncomplicated pumping. The excellent disintegration reduces both the tendency toward formation of layers as well as the viscosity of the medium – the energy requirement for mixing is minimized and the gas yield is increased. Easy to maintain Like the individual Vogelsang components for biogas plants, maintenance and parts replacement are quickly and easily performed with the BioCut and CC-Cut as well. All wear parts can be replaced on-site without dismounting the components. Here too, the excellent accessibility of the pumps for maintenance that Vogelsang customers appreciate is fully retained.

Optimally prepared in the fermentation process The RedUnit XRL twin-shaft shredder for processing high-volume solid matter The sturdy RedUnit XRL is primarily intended to reduce coarse material such as fruit, vegetables and other organic waste. Before they are fed into the digester, crops, food remnants and food industry waste must be prepared in such way that they can be optimally processed in the biogas plant without causing any interruptions. The RedUnit XRL increases the surface area of the substrate thereby accelerating fermentation while simultaneously protecting the biogas plant from trouble, damage and expensive repairs. The principle The RedUnit XRL uses its monolithic single-piece Ripper rotors made of special steel to shred the solid matter fed into it. The sharp ends and corners cut long-fibered matter while coarse and brittle components are ground up. The size-reduction ratio is adjusted by modifying the width and contour of the RedUnit blades. Easy-to-maintain design The Ripper rotors are mounted on generously sized shafts. In addition to the already very robust QD design with two-sided bearings, the rotors are produced from a single piece, which ensures high functionality and stability. The customer-oriented QuickService concept for which Vogelsang is known allows for fast, on-site maintenance. Advantages of the RedUnit XRL • Long service life thanks to rugged design • High availability since maintenance requires only minimal time • Economical shredding of large-volume and coarse substrates • Rapid decomposition and higher gas yield thanks to substrate preparation optimized for the digester

All too often, heavy material, such as metal and stones, complicates the lives of biogas operators. Aside from the fact that they become lodged in the digester and over time reduce the fermentation volume, they often cause damage and faults in pumps, mixers and other plant components. As the specialist for industry-specific pump technology, Vogelsang offers a solution for active heavy material separation with unrivaled energy efficiency: the combination of a passive heavy material separator and active foreign matter separation in the form of a sieve and non-contact clearing units. The compact DebrisCatcher therefore complements the Vogelsang portfolio for protecting pumps and plant components to ensure the target yield is achieved – and not impaired by fault-related operational interruptions. The principle The unique housing shape of the Vogelsang DebrisCatcher was developed with the help of flow simulations for optimal use of gravity for separation of metal parts and stones. The heavy material contained in the medium reliably sinks into the separator. Other foreign matter carried along with the liquid flow is retained at the sieve, from which it is guided into the separator by the rotating clearing units. Effective and durable The low speed of the clearing units combined with their non-contact manner of functioning reduces wear to a minimum. A counter bearing gives the drive shaft the stability it needs, even for stubborn foreign matter. In spite of the low drive power, high levels of torque are available. Flows of up to 150 m3/h are easily possible at DM content of up to 13 percent. This guarantees that the DebrisCatcher functions reliably – damage and blockages to pumps and fittings caused by foreign matter are avoided. Fully automatic removal of foreign matter with the DRS In combination with the innovative Vogelsang DebrisRemoval System, the DebrisCatcher can eject the foreign matter that has been separated out without requiring stoppages or opening the machine. Applications The DebrisCatcher is particularly suitable for biogas plants that handle pre-shredded substrates, such as corn silage or finely chopped grass silage, but which can also contain foreign matter, e.g., in the form of fresh slurry or amounts of manure.

Optimal substrate disintegration is key for determining biogas yield. This is why Vogelsang also offers a mechanical alternative for disintegrating substrates: the new, flexibly designed DisRuptor. The reduction of the particle size and the simultaneous defibering increases the surface area of the solid matter used. This helps bacteria reach the nutrients better, accelerates conversion and increases the gas yield. The principle The DisRuptor functional unit consists of a rotor with six blades as well as an outer DisRuptor ring. At high rotor speeds, the solid matter in the suspension is milled and frayed in the narrow gap between the rotor unit and the external ring. The gap can be individually adjusted to the specific application and the substrate. Thanks to these unique features, the DisRuptor offers particularly flexible and efficient mechanical treatment. Adjustable mechanism The DisRuptor adjustment mechanism is simple to handle. With hydraulic assistance, the DisRuptor head can be easily pivoted upwards to enable easy access to the functional unit. Few steps and no special tools are required to individually adjust the gap between the blades and the outer ring for each substrate. Economical side effect Since disintegration of substrates with the DisRuptor helps to prevent floating layers and reduces the viscosity of the organic suspension, power consumption and energy requirement of mixers and pumps is significantly reduced. Moreover, wear on the ring and blades can be compensated for by realignment – and their service life extended accordingly. Outstanding performance The DisRuptor, Vogelsang’s well-thought-out complement to the product range for biogas plants, has even won over independent committees of experts: The DisRuptor was the “WINNER 2016” of the EnergyDecentral INNOVATION AWARD. Advantages of the DisRuptor • Increases the target surface for the bacteria • Reduces the viscosity • Accelerates and increases gas production • Ensures high throughput

34 | 35 XSplit Clean separation of solid and liquid The XSplit® separator: economical and easy to maintain thanks to innovative design The XSplit® separator from Vogelsang combines the tried and tested concept behind press screw separators with a completely new design, resulting in unique features and many user advantages. When developing the new XSplit separator, Vogelsang took up the tried and tested functional concept of the press screw separator, and completely resigned the technical implementation. The drive is now arranged on the solid matter outlet side, which gives the XSplit an excellent cost-benefit ratio and unique features. Positioning the drive behind the solid matter outlet means there’s no need for an extra shaft seal. This reduces the both cost of spare parts and the time required for maintenance work. Access to the sieve basket and press screw is also possible in a few simple steps. As you’ve come to expect from Vogelsang, service and maintenance work can be performed quickly and easily on-site. In addition, the startup behavior of the new XSplit separator is significantly quieter in comparison. A sealing disc made of high-quality elastomer in the pressing area allows the XSplit to achieve a dry matter content of up to 40 percent – making it superior to other press screw separators. The disc ensures optimal resistance to the pressure applied by the press screw and, together with the press screw, ensures uniform and reliable plug formation without extra aids – with nearly zero initial leakage. A range of sieve variants suited to various media and consistencies is available, guaranteeing extremely reliable separation results. XSplit separator

No extra shaft seal required thanks to the innovative drive arrangement behind the solid matter outlet Individually adjustable pressing area for needs- based dry matter content Reliable plug formation Ideal separation results The easily accessible maintenance port provides very easy access to the press screw and sieve basket at any time. Advantages of the XSplit® • Up to 40 percent dry matter content • The dry matter content can be easily adjusted individually • Reliable plug formation without the addition of auxiliary agents • No extra shaft seal required • Easy to maintain and low-maintenance • Very good cost-benefi t ratio

38 | 39 Digestate and liquid manure management Make digestate useful Vogelsang agricultural technology for modern and economical management of digestate and liquid manure Soon after its establishment in 1929, Vogelsang was one of the most important manufacturers of tankers used in agriculture in northern Germany. The elastomer-coated rotary lobe pump invented by Helmut Vogelsang was used as mobile pump technology on slurry tankers – and was among the greatest advances in agricultural technology at that time. It is therefore no surprise that Vogelsang, which, in the meantime, has become a mechanical engineering company with worldwide operations, has never neglected the agricultural sector when it comes to novel products and further developed ones. Today, the respected manufacturer offers a range of solutions, as modern as it is comprehensive, for pumping and spreading liquid manure, digestate and other fluid fertilizers.

Vogelsang provides several options to meet this need: DosiMat DMX: A hydraulically driven cutting and dosing system that is fed from above and evenly distributes liquid manure and digestate to the outlets using a rotor. This design principle guarantees high distribution precision and high operational reliability. ExaCut ECL: The precision distributor based on rotor technology guarantees excellent cutting performance thanks to its self-sharpening cutting blades and distributes liquid manure and digestate homogeneously through 18 to 48 outlets. The integrated heavy material separator protects the entire spreading system from disruptive foreign matter. ExaCut ECQ: The fast and easy to maintain precision distributor with integrated heavy material separator and extended service life. Thanks to the special design of the cutting tools, the ExaCut ECQ distributes liquid manure and digestate with unbeatable accuracy through 24 to 48 outlets. Spreading close to the ground with Vogelsang trailing shoe and dribble bar systems To spread liquid manure and digestate with as low emissions and as nutrient-efficient as possible, Vogelsang offers a wide range of powerful dribble bar systems and trailing shoe systems. With working widths up to 36 meters for tankers and up to 18 meters for self-propelled vehicles, systems are available for farms and fields of any size. Depending on the towing vehicle, the umbilical systems are excellent thanks to their low weight, high distribution precision and even discharge distances. Many equipment options give farmers and contractors the necessary flexibility and allow them to do their work efficiently. Strip Till: Root-level liquid manure and digestate fertilization Aside from the conventional dribble bar and trailing shoe systems, Vogelsang offers Strip Till equipment to cater to the rising interest in Strip Tillage. Depending on the characteristics of the field, the XTill VarioCrop till the soil optimally for seeding row crops, combining tillage with root-level fertilization.
