The rotary lobe pump principle
How Vogelsang rotary lobe pumps work

The rotary lobe pump is a positive displacement pump. The pumping principle is based on two counter-rotating pumping elements, known as the rotary lobes. These are mounted on two synchronized shafts. The rotational movement of the lobes increases the volume of the pumping chamber on the suction side. This creates suction, which draws the medium into the rotary lobe pump. As the rotational movement continues, the medium is then enclosed in cavities between the rotary lobes and pump housing and it is issued on the discharge side by the pumping chambers as they reduce in size again; the rotary lobe pump conveys the medium directly. Due to their mirror-symmetrical design, rotary lobe pumps are independent of the direction of rotation and can pump in either direction without restriction. The HiFlo lobes developed in the 1990s operate pulsation-free, ensuring low-vibration and exceptionally gentle pumping.

The sturdy liquid manure pump for simple applications
Rotary lobe pumps of the R series for farmers

With the R series, Vogelsang offers sturdy yet powerful pump technology for simple liquid manure technology applications. These rotary lobe pumps have a double bearing, a generously dimensioned shaft diameter and a basic selection of sizes, rotary lobes and materials. The offset arrangement of the rotary lobes ensures that the pump runs with low pulsation. The rotary lobe pumps in the R series have proven themselves especially as classic pumps for liquid manure. The Vogelsang option for reliable use is not only highly resistant to dry running, the R series also allows priming even from deep pits. The reversible flow direction reduces the number of pipes on the tanker, as the rotary lobe pump can be used both on the tanker and as a mobile unit on a base. As a result, this liquid manure pump can be used flexibly throughout the entire farm. These basic properties make the R series rotary lobe pump an ideal liquid manure pump for agricultural applications.

Features of the R series

With our extensive selection of lobe geometry and materials, we will find the right long-life lobe for your media, e.g. NBR, NBR white, EPDM-SL, EPDM-AL, EPDM white, CSM, FKM, PU, stainless steel oder nitrided steel. The lobes can be produced in a straight, double-wing geometry or as 3-wing; 4-wing or 6-wing, pulsation-free HiFlo lobes.

Additional information:
Alongside the standard model in abrasion-resistant gray cast iron, versions in stainless steel are stocked as well. Other options for customization include heat treatment and wear-resistant coatings for the wear plates and housing components.
Axial wear plates are made from highly wear-resistant special steel and therefore extend maintenance intervalls. They offer protection for the entire pump chamber and therefore not only simplify maintenance, but also minimize downtime. At the same time costs are minimized.

Options of the R series

InjectionSystem for rotary lobe pumps by Vogelsang
The InjectionSystem significantly improves the foreign-matter resistance of the pump. It increases the efficiency and improves the suction capacity through optimized volumetric efficiency. Thanks to the InjectionSystem the service life of the pump is extended. Field trials prove a longer period of up to 2.5 times.

The liquid manure pump for occasional use
Rotary lobe pump R116

The R116 series from the R family offers a sturdy rotary lobe pump for occasional agricultural use. With a capacity of up to 4,500 l/min and pressures up to 5 bar, this pump is an ideal solution if liquid manure needs to be pumped occasionally.  It is flexible in use - whether as a liquid manure pump around the farm, as a filling and draining pump for tankers or as a mobile pump.

The flexible liquid manure pump for agricultural operations
Rotary lobe pump R136

The R136 offers sturdy pump technology with a capacity of up to 5,000 l/min and pressures up to 5 bar. That allows this series to be used flexibly. The rugged design and its features, such as the variety of lobes and materials or the axial wear plates make this series an ideal solution on agricultural operations.
