Self-priming pump Type A

The WANGEN progressing cavity pump Type A has swivel pushers inside the suction chamber that switch the pump from suction to pump mode. The pump is not sensitive to foreign objects and the deposition of foreign objects in the suction housing is not possible. In addition, hollow rotors ensure quiet operation.
