3.Simple structure, less wearing parts


Product Overview 

QBY Pneumatic diaphragm chemical pump pumping both liquid flow, but also conveying some of the easy flow of the media, with self-priming pump, submersible pump, shield pump, mud pump and other transportation machinery and impurities many advantages. 
Without irrigation water. Suction lift up to 5m. Head up to 50m. Outlet pressure ≥ 5bar.
Flow spacious, and good performance. Allows maximum particle diameter of 10mm.
Pumping slurry, impurities day-inch, little wear and tear on the pump;
Head, flow through the valve opening to achieve stepless adjustment (pressure adjustment between the 1-7 bar):
QBY stainless steel pneumatic chemical pumps with no moving parts, no seals, diaphragm pumps such as pumping media with moving parts, the media completely separated from the workpiece, the transmission medium does not leak out. So pumping toxic, or corrosive media play, will not cause environmental pollution and danger to personal safety;
Do not have electricity. In inflammable and explosive places safe and reliable;
QBY stainless steel pneumatic chemical pumps can be immersed in media work;
Easy to use, reliable, open stop simply open and close the gas valve. Even though no longer the case as an accident or sudden stop running the media will not result in damage to the pump. Once the overload, the pump will shut down from the earth, self-protection performance, when the load is back to normal, and can automatically start running;
Simple structure, less wearing parts, the pump of simple structure, installation, maintenance, pumping will not come into contact with the medium valve, joint rods and other moving parts, unlike other types of pumps due to the rotor, piston, gear, vane other parts of the gradual decline in performance wear and tear:
Can transport more viscous liquid (viscosity of 10,000 cps or less);
QBY Pneumatic diaphragm chemical pump without oil lubrication, even if idle. Has no impact on the pump, which is the most important feature of the pump.



As with air-powered, so flow with back pressure (outlet resistance) automatically adjust to changes, suitable for high viscosity fluids. The water pump operating point is set as the base good, if slightly higher for the viscosity of the fluid, you need to complete reducer or frequency converter, the cost will be greatly improved, and the gear pump is the same.
In an explosive environment with reliable and low cost air pump, such as fuel, gunpowder, explosives, transportation, because: first, grounded not produce sparks; Second, the work is no heat generated, the machine will not overheat
; Third, the fluid does not overheat because the diaphragm of the fluid agitation minimum.
