CIP self-priming pump adopts acid-resisting stainless steel (AISI 316) in valve body, which has unique acid and alkali resistance, and comply with sanitary requirements for foods. As a positive displacement pump, its features are superior to centrifugal pump since it suction liquid mixed with air or foams and even merely air. It is widely used to suction material with liquid level below the pump, For instance in the milking room,  it suctions milk from the milk barrel. It can also be used in automatic CIP cleaning system as  return flow pump in cleaning tank. The mechanical sealing is the build-in  influx type, and the temperature of suctioned  materiaI is no higher than 100℃.
