Börger Rotary Lobe Pumps are self-priming , valveless, positive displacement pumps. The even rotation of the rotor pair creates a vacuum on the priming side of the pump, which can be defined by the direction of rotation of the drive. This vacuum draws the liquid into the pump chamber. With further rotation, the pumped medium is conveyed past
