Diaphragm pumps also known as controls are the main types of actuators, by accepting the modulation control signal output unit, using power-operated to change the fluid flow. Diaphragm pumps and valves are generally composed of the implementing agencies. Using compressed air as power source, for a variety of corrosive liquids with particles in liquid, high-viscosity, volatile, flammable, poisonous liquid can be pumped optical exhaustion.

Pneumatic diaphragm pumps that they have four kinds of materials: plastic, aluminum, cast iron, stainless steel. Electric diaphragm pump that they have four kinds of materials: plastic, aluminum, cast iron, stainless steel. Diaphragm pump according to different liquid media were used nitrile rubber, chloroprene rubber, fluorine rubber, polyvinylidene fluoride, poly ethylene 46. To meet their needs. Placed in a variety of special occasions, be used to pumping kinds of conventional pumps can not pump the medium.
