Sanitary Diaphragm Pump, Air Operated Diaphragm Pump, Double Diaphragm Pump

Conventional Diaphragm Pump Sanitary Diaphragm Pump

The sanitary diaphragm pump is a positive displacement pump that utilizes the reciprocating action of membrane to cause volume change. It has a slight influence on rotating materials, meaning it is ideal for handling unstable materials, such as toxic liquids.

Structure Chart Features As it is not driven by electric power, it features a safe ground connection and normally works under water. Add valves in the outlet for flow control. Good dry running performance. An extensive range of fluids, from low viscosity to high viscosity. It can pump the fluid with solid content, while the ball valves prevent blockages from occurring. No need for lubrication and maintenance, as the pump does not leak and will not contaminate the environment. High efficiency all the time.
