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.
