Diaphragm Metering Pump

Diaphragm Metering Pump


Diaphragm metering pump is a branch product of metering pump. Its working principle is that the reciprocating movement of diaphragm forms the volume change of pump chamber, and controls the flow direction of materials through one-way valve to play the function of metering and transportation.

Diaphragm metering pump is a commonly used metering pump. It uses diaphragm as the main component of hydraulic end, with good sealing performance and no leakage. According to different use needs, the components of our series of metering pumps can be customized with different materials.
