QBY Pneumatic Diaphragm Pump

QBY Pneumatic Diaphragm Pump--Product overview

QBY series pneumatic diaphragm pump is a new type of conveying machinery, which is a novel type of pump in China. Using air compressor to compress air as the power source, all kinds of corrosive liquids, liquids with particles, high-viscosity, volatile, flammable, and highly toxic liquids can be exhausted. Its performance parameters are similar to those of WLLDENPVMPS of the Federal Republic of Germany and MARIOWPUMPS of the United States. The factory has formed a series of production at present, with a total of eight specifications and diameters: 10mm (3/8"), ￠15mm (1/2"), ￠25mm(1 "), ￠40mm( 1 1/2"), ￠50mm(2"), ￠65mm( 2 1/2"), ￠80mm(3"), ￠100mm(4"). Three materials, aluminum alloy, cast iron, stainless steel. Diaphragm pumps use nitrile rubber, neoprene, fluorine rubber, and polytetrafluoroethylene according to different liquid media. To meet the needs of different users. Since the pump was put into production, it has been adopted by more than 1,000 domestic petroleum, chemical, electronic, ceramic, textile, paint, and pharmaceutical machinery system units. It is placed in a special occasion and used to pump various media that cannot be pumped by conventional pumps. And the ideal products to replace the gear pump have achieved satisfactory results.

QBY Pneumatic Diaphragm Pump--Model significance

QBY Pneumatic Diaphragm Pump--Product features

1. No need to irrigate and divert water, the suction lift is up to 7m, the head is up to 50m, and the outlet pressure is ≥6kgf/cm2;

2. The flow is spacious, the passing performance is good, and the diameter of large particles up to 10mm is allowed to pass. When pumping mud and impurities, there is little wear on the pump;

3. The head and flow can be adjusted steplessly through the valve opening (air pressure adjustment is between 1-7kgf/cm2);

4. The pump has no rotating parts and no shaft seal. The diaphragm completely separates the pumped medium from the moving parts and working medium of the pump, and the conveyed medium will not leak out. Therefore, when pumping toxic, easy-to-use or corrosive media, it will not cause environmental pollution and endanger personal safety;

5. There is no need to use electricity, and it is safe and reliable to use in flammable and explosive places;

6. It can be immersed in the medium to work;

7. Convenient function, reliable work, start and stop simply open and close the gas valve, even if there is no medium running for a long time due to accidents or sudden shutdown, the pump will not be damaged due to this, and the pump will automatically be overloaded. Ground shutdown, with self-protection performance, when the load returns to normal, it will automatically start operation;

8. Simple structure and few wearing parts. The pump has a simple structure and is easy to install and maintain. The medium conveyed by the pump will not come into contact with moving parts such as the valve, linkage, etc., unlike other types of pumps due to rotors, pistons, gears, The wear of blades and other parts causes the performance to gradually decline;

9. It can transport relatively viscous liquids (viscosity below 10,000 centipoise);

10. The pump does not need to be lubricated with oil. Even if it is idling, it will not have any effect on the pump. This is a major feature of the pump.
