Portable Air Driven Double Diaphragm Pump For Chemical Petrochemistry

Portable Air Driven Double Diaphragm Pump For Chemical Petrochemistry

Air Driven Double Diaphragm Pump Advantage

1. No irrigation water, suction up to 5 meters, head up to 70 meters, the outlet pressure > 7bar
2. Wide flow and good performance, which allows the maximum particle diameter of 10 mm. Pumping mud, impurities, minimal wear and tear on the pump
3. Head, flow through the valve open to realize the stepless adjustment (pressure regulator between 1-7bar)
4. The pump has no moving parts, no seals, diaphragms exhausted medium and pump running parts, working medium is completely separated from the transmission medium does not leak out. So pumping toxic, volatile or corrosive media, will not cause environmental pollution and danger to personal safety.
5. Do not have electricity, flammable and explosive places safe and reliable.
6. Can be immersed in the medium.
7. Easy to use, reliable, open stop simply open and close the gas valve, even for long periods because of accident or sudden stop running without media will not result in damage to the pump, once the overload, the pump will automatically shut down, with self-protection performance, when the load is back to normal, and can automatically start running.
8. Simple structure, less wearing parts, the pump is simple to install, easy maintenance, pumping medium can not come into contact with the valve and coupling lever and other moving parts, unlike other types of pumps due to the rotor, piston, gear, vane leaving other parts of the wear performance of gradual decline
9. It can transmit the adhesive liquid (viscosity less than 10,000 cps)
10. This pump works without oil lubrication, even idling; it has no influence on the pump, which is a major feature of this pump.
