The performance of the pneumatic diaphragm pump

08 - 07

pneumatic diaphragm pump is a double suction diaphragm pump cavity, of course, there are single lumen of pneumatic diaphragm pump, but there is no double suction flow and head must be very big membrane pump, pneumatic diaphragm pump its service life is long, if the internal quality of diaphragm, pneumatic diaphragm water pump service life can reach more than 10 years, the pump will not stop, never card machine, the advantages of both can conveying flow of liquid medium, also can not easy flow of medium, dust, even has a self-priming water pump, submersible pump, mud pump, shield pump, such as integrated the advantage is a powerful diaphragm pump, mainly with compressed air as power source, generally air compressor drive, for corrosive liquid, with particles of liquid can be smoked light net, because without the motor itself, so can be safely used in flammable and explosive occasions. Also can be used in immersed in liquid medium, idling and pump, since there is no rotating parts, excluding shaft seal, so it is against the leakage of the pump.

1。 Without irrigation water diversion, up to 7 m, suction lift up to 70 m, outlet pressure 0 or less. 8 mpa

2。 Flow and spacious, with good performance, allows larger particles diameter 9. 4 mm, pumping mud, impurities, the pump wear little:

3. Head, flow, can be adjusted by air pressure ( Air pressure in the 0. 1 - 0. Between 8 mpa) ；

4。 The scope of the work environment: 5 - 65℃； The medium range ( - 20℃- 150℃） ；

5。 The pump has no rotating parts, there is no shaft seal, the diaphragm will pumping medium completely separated from the moving parts of the pump, the working medium, the transmission medium will not leak out. Therefore, pumping toxic volatile cargo corrosive medium, not cause environmental pollution and harm the personal safety;

6。 Need electricity, not to be used in inflammable and explosive places safe and reliable;

7。 Can be immersed in the medium;

8。 Convenient, reliable operation, leaves open stop simply open and closed gas valve, even if long time no medium due to unexpected run or stop suddenly, pump and will not be damaged. Once the overload, the pump will automatically stop, have self protection performance, when the load is back to normal after, can automatically start running again.

9。 Simple structure, less wearing parts. The pump has simple structure, easy installation, maintenance. will not come into contact with the medium of the pump valve, the moving parts such as connecting rod, don't want to other types of pumps for rotor water pump, piston, gear, blade and other parts wear and make the performance decline gradually;

10。 To lose the sticky liquid ( Viscosity under 10000 centipoise) ；

11。 This pump without lubricating oil, even if the idling, is without any effect on the pump. This is the pump a feature.

There are many issues that affect pool cover drain pump, which has led to the need of getting specialists trained in certain areas so as to handle all issues that may arise as well as submersible pump products that can solve winter cover pump problems.
