Principle of operation
Rotary lobe pumps are self-priming valveless positive displacement pumps and are based on the operating principle of a rotating positive displacement pump. To generate the delivery pressure, a pair of symmetrical rotors are arranged in a housing without contact and rotate in opposite directions. In the course of one revolution, pumping chambers are formed between the rotor blades and the inner wall of the housing, in which the pumped medium is pumped from suction to discharge side without pulsation. Due to the gentle and speed-proportional delivery of the rotary lobe pump, KD PUMPS also transport pumped media with large particle sizes without difficulty.
