1. Pneumatic single -diaphragm pump

principle

The pneumatic diaphragm pump uses compressed air as the source of power. It is a volume pump that causes volume change from the reciprocating of the film. Its working principle is similar to the plunger pump.

The pumping of pneumatic diaphragms has four materials: engineering plastic, aluminum alloy, cast iron, stainless steel. The pneumatic diaphragm pump adopts chip rubber, chlorine rubber, fluorine rubber, polytrafluoroethylene, and poly four ethylene according to different liquid media.

Tado rubber is mainly used in petrochemical and oil -containing liquids, with good elasticity. Temperature limit: -12.2 ℃ to +82.2 ℃, +10 ° F to +180 ° F.

Prime rubber is widely used in applications without corrosiveness. It has the characteristics of long life and low cost; temperature limit: -17.7 ℃ to +93.3 ℃, 0 ° F to +200 ° F.

In the case of extremely high temperature, fluorine rubber is very effective. It can be used for some acids and alkali products. But the cost is high and the life span is short. Temperature limit: -40 ℃ to +175.7 ℃, -40 ° F to +350 ° F.
