Lobe pump PLP

Pomac PLP lobe pumps are designed to achieve maximum pump performance combined with minimal product damage. Specific attention is paid to the bearing construction and the rigidity of the shaft. The design is kept as compact as possible while the lobe displacement volume is optimised.

This makes the PLP range suitable for high working pressure up to 15 bar. The application range consist of capacities up to 110 m³/h.

The entire pump section as well as the gearbox is made out of stainless steel. The pump can be easily cleaned.

The distinctive 'front pull out' mechanical seals ensure easy maintenance. The possibility to mount the pump horizontally as well as vertically makes it universally applicable.
