Börger Rotary Lobe Pumps are self-priming, valveless, positive displacement pumps. Two synchronized rotors rotating against each other build chambers towards the pump casing. At the suction side the open chambers fill with the conveyed product. The product is displaced in the direction of the volume flow into the discharge side. The capacity is speed related and the flow is reversible. At standstill the rotors the pump nearly perfect seal.
Pumping capacity up to 1.000 m3/h (5.000 usgpm)
Discharge head up to 120 m
