High Pressure Air Driven Double Diaphragm Pump For Chemical Industry

Air Driven Double Diaphragm Pump Introduction

1. Firstly, the stainless steel material has strong pressure tolerance and is the best choice for some diaphragm pumps with high pressure demand;

2. Free from rust and pollution, which greatly protects the cleanliness of medium. It is an excellent choice for some medical units, food processing enterprises and beverage industry.

3. It is doomed to be safe and quiet if it is powered by air.

4. Don't worry about the danger caused by wires and engines

5. Simple structure, convenient installation and maintenance, and the pump conveying medium will not touch the valve.

6. Roomy flow with good passing performance, allowing the maximum particle diameter up to 10 mm. When pumping mud and impurities, there is little wear on the pump;

7. It can deliver relatively sticky liquid (the viscosity is below 10000 mm);

8. The head and flow can be adjusted stepless through the opening of the air valve (the air pressure is adjusted between 2-/8.3bar).

9. Easy to use, reliable to work, simply open and close the gas valve, and the pump will stop running automatically when the pipeline overpressure

10. No irrigation water is required. The suction range is up to 7 meters, the head reaches 83 meters, and the outlet pressure is up to 8bar

11. The pump has no rotating parts, no shaft seal, and the medium pumped by the diaphragm is completely separated from the moving parts and workpiece media of the pump. The medium transported will not leak outward.

12. Can make a variety of pump materials with good corrosion resistance
