QBK pneumatic diaphragm pump is a new type of conveying machinery, adopting compressed air as the power source, which has the advantages of long service life and will not stop. Its performance parameters are similar to those of WLLDENPVMPS of Federal Germany and MARlOWPUMPS of the United States. It can not only pump the flowing liquid, but also can transport some medium which is not easy to flow, for all kinds of corrosive liquid, liquid with particles, high viscosity, volatile, flammable, highly toxic liquid, can be pumped up and sucked out. QBK air operated diaphragm pump has many advantages of self-priming pumps, submersible pumps, shielding pumps, slurry pumps and impurity pumps and other conveying machinery.

QBK pneumatic diaphragm pump performance:

1、No need to pour water, suction range up to 6m, head up to 70m.

2, flow spacious, through the performance is good, allowing through the largest particle diameter of 10mm. pumping slurry, impurities, the pump wear and tear is very little.

3、Lift and flow can be steplessly adjusted through the valve opening (air pressure adjustment between 1-8bar).

4、Because the diaphragm will convey the medium and the pump moving parts completely separated, so the medium will not leak outward. Conveying toxic, easy to play or corrosive media, will not cause environmental pollution and jeopardize personal safety.

5, do not have to use electricity. Safe and reliable to use in flammable and explosive places.

6, can be submerged in the media work.

7, easy to use, reliable, open and stop simply open and close the gas valve, even if due to unforeseen circumstances and a long time without media operation or sudden shutdown, the pump will not be damaged. Once overloaded, the pump will automatically stop, with self-protection performance, when the load returns to normal, and can automatically start running.

8、Simple structure, less wearing parts, the pump structure is simple, easy to install, easy to maintain, the Diaphragm pump conveying medium will not contact the gas distribution valve, coupling rod and other moving parts, unlike other types of pumps due to the wear and tear of the rotor, piston, gears, vane and other parts of the performance of the gradual decline: the pump can convey more viscous liquids.

9、Can transport viscous liquid (viscosity below 10,000 centipoise).

10, the pump does not require oil lubrication, even if idling, the pump does not have any effect, which is the pump's larger features.
