Air operated double diaphragm pump
Mine diaphragm pumps produced by our company adopts, absorbs and improves the most advanced production technology and technology of pneumatic diaphragm pumps in the world. This product is specially designed for coal mines and has traditional submersible electric pumps, mud pumps, impurity pumps, All the functions of the flexible shaft pump are a revolution of the traditional mine water pump. The key is to completely solve the safety problem of traditional water pump,which can provide high delivery speed even under low air pressure and is compatible with a wide range of materials, and has an anti-stall design, modular air motor / fluid part.They can be applied in underground mines to discharge clean water or sewage containing solid particles (volume concentration less than 2%), and also be used in non-coal mines and other occasions with similar conveying media.
Air operated double diaphragm pump working environment conditions
1. Compressed air for power use, the pressure should be in the range of 0.2 ~ 0.7mpa;
2. The temperature of the conveying medium shall not exceed 40ºC;
3. The PH of the conveying medium is in the range of 4 ~ 10;
4. The maximum diameter of solid particles shall not exceed 6 ~ 9mm, and the volume concentration shall not exceed 2%;
5. Ambient temperature: -20ºC ~ 50ºC;
6. Ambient humidity: ≤95% (when ambient temperature is +25ºC);
7. Atmospheric pressure: 80kPa ~ 106kPa;
8. It is suitable for coal mine underground coal dust and methane explosive gas danger place, but does not destroy the insulation corrosive gas place.
