Working principle of diaphragm pump:

Diaphragm pump is a special form of positive displacement pump. It changes the volume of the working chamber by the back and forth agitation of a diaphragm, so as to inhale and discharge liquid.

Classification of diaphragm pump:

Diaphragm pumps are classified into pneumatic diaphragm pumps and electric diaphragm pumps

Pneumatic diaphragm pump has five commonly used materials: plastic, aluminum alloy, cast iron, stainless steel and Teflon.

The electric diaphragm pump has four kinds of materials: plastic, aluminum alloy, cast iron and stainless steel. The diaphragm of the diaphragm pump adopts nitrile rubber, neoprene, fluororubber, polytetrafluoroethylene and polytetrafluoroethylene according to different liquid media, which are placed on various special occasions to pump various media to meet the needs.
