Pneumatic diaphragm pump is a new type of conveying machinery, using compressed air as the power source, for all kinds of corrosive liquids, liquids with particles, high viscosity, volatile, flammable, highly toxic liquids, can be pumped out.

Pneumatic diaphragm pump is a new type of conveying machinery, is a new type of pump in China. Using compressed air as power source, it can be used for all kinds of corrosive liquids.

Pneumatic diaphragm pump has four materials: engineering plastic, aluminum alloy, stainless steel, cast iron. Pneumatic diaphragm pump according to different liquid media respectively using nitrile rubber, neoprene rubber, fluorine rubber, polytetrafluoroethylene, polytetrafluoroethylene, etc., to meet the needs of different users. Placed in a variety of special occasions, used to pump a variety of conventional pump can not pump the medium, have achieved satisfactory results.

Because the pneumatic diaphragm pump has the above characteristics, the pneumatic diaphragm pump is gradually invading the market of other pumps since its birth, and occupies a part of it. For example: spray painting, ceramics industry pneumatic diaphragm pump has occupied a dominant position, and in some other industries, such as environmental protection, wastewater treatment, construction, sewage, fine chemical industry is expanding its market share, and has other pumps irreplaceable status.

Working principle and characteristics

Pneumatic diaphragm pump is a kind of compressed air as the power, by the diaphragm reciprocating deformation caused by the volume change of the positive displacement pump, its working principle is similar to the plunger pump, due to the characteristics of the working principle of the pneumatic diaphragm pump, so the pneumatic diaphragm pump has the following characteristics:

1, the pump will not overheat: compressed air for power, in the exhaust is an expansion heat absorption process, the temperature is reduced when the pneumatic pump is working, no harmful gas discharge.

2, no electrical spark: the pneumatic diaphragm pump does not use electricity for power, and prevents electrostatic sparks after grounding.

3, it can be passed by liquid containing particles: because of the positive displacement work and the inlet is a ball valve, it is not easy to be blocked.

4, the shear force on the material is very low: how to suck in and spit out when working, so the agitation of the material is small, suitable for the transport of unstable substances.
