Börger Rotary Lobe Pump

Borger Rotary Lobe Pumps are made of few individual parts. Instead of adopting the widely used segmented pump design, the different size casings and rotors are manufactured in a single-piece construction. The result: robust and compact Rotary Lobe Pumps characterized by quiet, safe and reliable operation, long service life and excellent ease of maintenance.

Wear parts can be quickly accessed or replaced by operation and maintenance staff, without the removal of piping or drive systems.

This kind of simplicity is B.rger's principle. The B.rger Rotary Lobe Pump features a cantilevered shaft design. The pumps can be arranged in a variety of mounting positions and

are suitable for multiple drive types including electric motors, combustion engines and hydraulic motors. Even complete mobile units pose no problem and are manufactured in

company-owned workshops.

Borger Rotary Lobe Pumps are self-priming, valveless, positive displacement pumps. Rotors, synchronized by the timing gear, are fastened to two parallel shafts rotating in opposite direction. As the rotor pair counter rotates, a cavity is created at the suction side. The resulting chamber fills with the pumped fluid.

The medium is conveyed between lobe surfaces and the surrounding pump casing and then displaced into the casing opening at the discharge side. The flow direction can easily be reversed by changing the direction of rotation. Borger Rotary Lobe Pumps are therefore very well suited for reversing operation.
