Paints, oils, or additives, adhesive or abrasive – in the chemical and petrochemical industry, pumps have to withstand quite a lot. Extremely low-viscosity media pose almost as great a challenge as high-viscosity liquids, because the flow rates are generally greater and the pressure comparatively high. In addition to the pump‘s basic mechanical load capacity and delivery capacity, another question is becoming increasingly pressing: general economic efficiency. Vogelsang rotary lobe pumps have long proven themselves in this regard thanks to their robust and easy-to-maintain design. With the EP series pumps, you can now benefit from these advantages in even more areas of application. This is because they have been specially designed for extreme conditions and continuous high pressures up to 18 bar. They can pump even abrasive, chemically aggressive, and ignitable media with temperatures up to 200° C with the reliability typical of Vogelsang pumps. Fewer sealing points, better flow properties It is the new, flow-optimized housing of the pumps in the EP series which not only makes them exceptionally robust but also gives them outstanding efficiency. The housing consists of a single casting, which is why it has very tight tolerances. Due to the reduction in ribbing, welds, and grooves, it is nearly free of dead space, so the fluids flowing through it cannot collect anywhere and form germs, or oxidize. This also enables the use of cleaning methods such as CIP and SIP. The pump chamber is connected to the pipes by means of a Quick connection with O-ring sealing, designed for high flange loads. Also designed to optimize flow, this connection contributes to trouble-free delivery too. Invincible up to 200° C A new, flow-optimized, one-piece housing and a choice of different seals make EP series pumps more heat-resistant than ever before. Options • Supply systems for flushing plans in accordance with API 682 etc. • Innovative ASU seal support system for longer bearing life • ATEX conformity and TA-Luft conformity • Stainless steel version • Axial and radial wear plates for abrasive media • CIP-SIP conformity • QuickService housing protection

Advantages of the EP series • High differential pressures of up to 18 bar are possible • Incomparable running smoothness due to high- performance gearbox • High efficiency due to one-piece housing • AirGap to protect the gearbox in the event of leakage • Alternative seals per industry standards and customer requirements (see p. 17) • Quick connection for higher flange loads and easy maintenance

HiFlo lobes Pulsation-free pumping for exceptionally smooth running – available in a wide range of versions Housing variants Choice of steel or stainless steel QuickService design Quick and easy access to all wetted components without removing the pump from the pipe Axial and radial wear plates Made of highly wear-resistant special steel, to extend service life and facilitate maintenance Seals Available with proven Vogelsang Quality Cartridge and as API-compliant or pressure-resistant seals, e.g. for adhesive media One-piece housing Flow-optimized, with smooth surfaces and fewer sealing and weld points

As customers from the chemical and process industry or the food sector will tell you, who have long relied on Vogelsang‘s trusty rotary lobe pumps: you can depend on this technology. And not only because the pumps effortlessly transport abrasive, aggressive, viscous, or contaminated media such as paint, sugar, wine or raw materials for the construction chemistry from A to B. Depending on your requirements, you can choose between different sizes, delivery rates, speeds, and differential pressures. With the rotary lobe pumps of the VY series, Vogelsang remains true to these characteristics, which are very important for the economic effi ciency of a pump. However, to better meet the highly demanding applications of industry, the housing of these pumps is designed in one piece and with a minimum of sealing points, like that of the EP series pumps. This manufacturing technique results in a high-precision, fl ow-optimized end product that is highly effi cient even with diffi cult media. The VY housing is also low in dead space and prevents the accumulation of residues. Demand-oriented, performance-optimized, economical The performance spectrum of VY series rotary lobe pumps ranges from 1m³ / h to 120 m³ / h at a max. pressure of 10 bar. Naturally, these features also affect the size of the pump. The general rule is: as compact as possible, as powerful as necessary. This not only saves precious space, but also a lot of energy. VY series pumps can also be equipped with double mechanical seals designed for specifi c applications. Options • ATEX and TA-Luft compliant • Supply systems for fl ushing plans in accordance with API 682, etc. • Stainless steel version • Axial and radial wear plates for abrasive media • ASU seal support system to extend seal service life (see p. 18) Advantages of the VY series • High effi ciency even with demanding media • Variety of models for a wide performance spectrum • Cleaning according to CIP or SIP processes • Alternative seals per industry standards and customer requirements (see p. 17) • Quick connection for higher fl ange loads and easy maintenance

Holding tight no matter what New seals for even more versatile use of Vogelsang rotary lobe pumps High pressures, extreme temperatures, aggressive media – in the production of paper, paint, or adhesives, as well as in the oil and gas industry or the chemical sector, seals in pumps are exposed to particularly high stress. That‘s why Vogelsang worked with well-known manufacturers to develop two new kinds of sealing system that allow EP and VY series pumps to be used in precisely those environments. The new seals not only comply with specifi c industry standards, they also increase the reliability of the pumping process and thus help to ensure plant availability. Less frequent service deployments also reduce the operating costs of the already low-maintenance Vogelsang rotary lobe pumps. The EP and VY series pumps can be equipped with various sealing systems. They can therefore be used fl exibly in demanding fi elds such as paper production, the pumping of paint and adhesives, the oil and gas industry, and the chemical sector.

To ensure that seals do their job reliably over the long term, pumps in many industrial plants are equipped with complex seal support systems. They continuously supply the seal with the appropriate buffer fl uid and maintain the necessary pressure in the buffer chamber. This protects the sliding surfaces so the seal can fulfi ll its task for the long term. The problem is the large number of components and units that conventional seal support systems require to perform these tasks. In addition to the additional space required, companies are faced with high acquisition costs that sometimes even exceed those of the pump itself. Maximum performance in a mini format: the Automatic Supply Unit As customer-oriented pump specialists and industry experts, Vogelsang‘s design engineers have now found a revolutionary solution to this predicament too. The new Automatic Supply Unit (ASU) is barely larger than a beverage can and, unlike conventional seal support systems, it is based on a principle that is as simple as it is ingenious: If there is a drop in pressure, a reciprocating pump pumps the selected buffer fl uid into the seal chamber with each revolution of the mechanical seal. The seal chamber pressure is kept constant at either 2.0 or 4.3 bar. Thanks to the small dimensions of the patented new ASU, Vogelsang‘s compact rotary lobe pumps can be installed in the smallest installation spaces, even with the seal support system included. An ingenious idea that is so far unique in the world: Installing an ASU extends the life of a seal by up to 50 % and reduces the maintenance costs by 25 %. Plant operating costs fall while plant availability rises. And the price? More than manageable when compared to conventional seal support systems. Which is why Vogelsang‘s ASU makes previous standards obsolete, and is the new benchmark in the fi eld of professional seal support systems. As simple as it is ingenious: even the slightest drop in pressure is automatically and simultaneously compensated by the interaction of the reciprocating pump and the seal. Available in two versions: • For 2 bar seal chamber pressure and applications up to 3 bar differential pressure • For 4.3 bar sealing pressure and applications from 3 bar to 7 bar differential pressure Advantages of the Automatic Supply Unit – ASU • Compressed seal supply system at an economical price • 1,5 x longer service life • 25 % fewer seal changes • Declining operating costs with increased system availability • Energy saving because no own drive • Small installation space • Easy to maintain
