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.
Maintenance of Vogelsang rotary lobe pumps
How to disassemble a VX pump
- Open the cover:
Unfasten four nuts, remove the cover and you have free access to the pumping chamber. If necessary, you can also replace the wear plate of the cover at this stage.
- Dismount the rotary lobes:
Unfasten the strain bolts, remove the pressure discs on the lobes. Then place the puller on the lobes and dismount them.
- Remove the wear plates:
After you have removed the lobes, all you have to do is remove two screws and you can remove the wear plate at the gearbox side.
- Remove the Quality Cartridge mechanical seal:
Using a simple pull-out device, you can now pull out the Cartridge mechanical seal and then replace it just as easily.
Insert the wear plate at the gearbox side, fasten it with two screws, install the lobes and fasten them on the shaft with pressure discs, and put the cover in place.

Control technology for Vogelsang technology
Investing in our progressive and smart control technology significantly boosts the performance and efficiency of Vogelsang machines and systems. It captures and continuously monitors key parameters like the capacity or throughput rate, rpm, pressure and power consumption. The control detects malfunctions early, and rectifies them by intervening appropriately. The integrated communication interfaces like ProfiNet and OPC UA can exchange data with other systems or a superordinate control in real time.
At the same time, the web-based user interface displays all key data clearly in all major browsers. Optionally, the data can be accessed on mobile devices for remote monitoring.
Our experts’ experience from hundreds of applications in various areas constantly inspires our software development and lays the foundation for the major benefits for the users: low operating costs, maximum availability and efficiency.
Our range of controls offers the right solution for all machine requirements and all customers’ needs. From ready-to-use, factory-tested and commissioned system solutions for end users, to basic versions for experts who want to put the finishing touches to the control technology themselves.
