The all-round rotary lobe pump for biogas plants

Rotary lobe pumps in the VX series for biogas applications

The biogas pumps of the VX series are the ideal solution for many pumping tasks in biogas plants. They reliably convey liquid manure, greases, flotation tailing and other liquid media – directly to the digester, the mashing tank or the liquid feeding system, or to digestate dewatering. The patented HiFlo® lobes enable pulsation-free and low-vibration pumping.

In many biogas plants, rotary lobe pumps from the VX series act as the central pump. They prime liquid manure out of pits, evacuating air from empty pipes in the process. Even if the liquid manure contains foreign matter such as stones and screws: thanks to the InjectionSystem and the large free passage, Vogelsang biogas pumps are resistant to foreign matter. Even organic suspensions, recirculate or low-viscosity digestate can be pumped without difficulty, e.g. from the digester to the post digester and vice versa: By changing the direction of rotation of the drive, it is easy to reverse the flow direction. This characteristic is also an advantage for tankers, as only one pump is needed for both filling and draining. The VX series stands out here thanks to its small space requirements: The biogas pumps can generally be installed easily on a vehicle or in the space between the digester and post digester.

Thanks to the QuickService concept, they can be serviced or repaired quickly and simply on site. All wear parts can be changed without dismounting and with limited space requirements, in order to restore 100% of the capacity.
