Biogas plant

The operator of a biogas plant was not satisfied with the rotary lobe pumps in use made by a competitor. The pumps showed signs of severe wear on the rotors after just a few weeks. There were also frequent occurrences of damage to the seals and gears. The operator of the biogas plant conducted a year long test to find the optimum pump for his requirements. Several pumps were tested. At the end of the test phase, the customer appointed 40 Boerger Rotary Lobe Pumps to be installed in the biogas plant.

 The impeccable quality and low maintenance design of the Boerger Rotary Lobe Pump impressed the customer, particularly the Boerger Premium profile rotors, which were especially developed for the biogas sector. Fibrous matter in renewable resources is captured in the profile grooves of the Premium profile rotor. This constantly exchanging film forms all over the seal between the rotors and the casing. Besides the high level of  pump efficiency, this patented technology enables premium profile rotor operation be virtually free of wear.
