Product Introduction

Pneumatic diaphragm pump introduced

Pneumatic diaphragm pump is used in coal mine drainage clean water, or containing solid particle impurities (volume concentration less than 2%) sewage, can also be used for non-coal mountains, transport medium similar to other occasions.

Pneumatic 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 40℃;

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: -20℃ ~ 50℃;

6. Ambient humidity: ≤95% (when ambient temperature is +25℃);

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.
