Vogelsang rotary lobe pumps are straightforward to maintain, come in an impressive range of sizes and designs, have numerous equipment options and material variants, and various drive possibilities and installation options. All the models have two things in common: a compact design and easy maintenance. With four pump series and multiple models, up to eight sizes per model, Vogelsang pump technology can be adapted to almost any application, delivery rate and pressure range. It will economically pump anything that flows.
Rotary lobe pumps are self-priming even from a depth of as much as 9 meters. They resist dry running and retain high efficiency if the pumped medium contains foreign matter. Vogelsang rotary lobe pumps feature capacities of up to 1,400 m3/h and up to 16 bar pressures. They can reliably convey low-viscosity to highly viscous media, either pure or with a high solid matter content. Perfect for an economical solution.
How Vogelsang Rotary Pumps Work
Operating Principal of Rotary Pumps by Vogelsang
The rotary lobe pump is a positive displacement pump. The pumping principle is based on two counter-rotating elements, 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 rotation creates suction, which draws the medium into the rotary lobe pump. As the rotational movement continues, the medium is enclosed in cavities between the rotary lobes and pump housing. The pumping chambers issue it on the discharge side 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.

Vogelsang Rotary Lobe Pump Applications
The Vogelsang rotary lobe pump is no longer used exclusively in the agricultural sector. In addition to pumping liquid manure, the rotary lobe pump is also a reliable partner in many other applications such as wastewater and biogas.
- Biogas: Pumping organic suspensions, digestates etc. in biogas plants is a daily application for which Vogelsang can offer the right pump technology.
- Municipal Markets: Whether used in a pumping station or in the sewage treatment plant itself, the Vogelsang rotary lobe pump performs its duty just as reliably at it does in stationary disposal stations or in internal building disposal systems.
