Pneumatic diaphragm pump is a new type of conveying machinery, which is a relatively new type of pump in China at present. The pneumatic diaphragm pump products manufactured by the pneumatic pump manufacturer use compressed air as the power source. All kinds of corrosive liquids, liquids with particles, high viscosity, volatile, flammable and highly toxic liquids can be pumped out.

Pneumatic diaphragm pump has four materials: plastic, aluminum alloy, cast iron and stainless steel. The diaphragm pump adopts NBR, neoprene, fluororubber, polytetrafluoroethylene and polytetraethylene according to different liquid media. To meet the needs of different users. It is placed in various special occasions to pump media that cannot be pumped by conventional pumps, and has achieved satisfactory results.

Working principle of pneumatic diaphragm pump:

In the two symmetrical working chambers of the pump, each is equipped with an elastic diaphragm. The connecting rod connects the two diaphragms into a whole. After the compressed air enters the air distribution valve from the air inlet connector of the pump, it drives the diaphragm action in the two working chambers to drive the two diaphragms connected by the connecting rod to move synchronously.

At the same time, the gas in the other working chamber is discharged from the back of its diaphragm outside the pump. Once it reaches the end of the stroke, the air distribution mechanism will automatically lead the compressed air into the other working chamber to drive the diaphragm to move in the opposite direction, thus forming a synchronous reciprocating operation of the two diaphragms.

Each working chamber is also provided with two one-way ball valves. The reciprocating movement of the diaphragm changes the volume of the working chamber, forcing the two one-way ball valves to open and close alternately, so as to continuously suck and discharge the liquid.

Purpose of pneumatic diaphragm pump:

1. It can pump all kinds of sewage.

2. It can pump various chemical corrosives, oil, mud, and clean oil dirt.

3. It can suck all kinds of highly toxic, flammable and volatile liquids.
