Product Introduction
The diaphragm pump receives control signals from the modulation unit output. Diaphragm pumps use power operation to change fluid flow rate. There are several materials available for diaphragm pumps: plastic, aluminum alloy, cast iron, and stainless steel. Electric diaphragm pumps use nitrile rubber, chloroprene rubber, fluororubber, polyvinylidene fluoride, and polytetrafluoroethylene according to different liquid media. To meet the needs. Placed in various special occasions, used to pump media that cannot be pumped by conventional pumps.
