Pneumatic diaphragm pump overview

      QBY series pneumatic diaphragm pump is a new type of conveying machine, which is a new type of pump in China. The air compressor is used as the power source for compressed air. For various corrosive liquids, liquids with particles, high viscosity, volatile, flammable and highly toxic liquids can be exhausted. Its performance parameters are similar to WLLDENPVMPS in the Federal Republic of Germany and MARIOWPUMPS in the United States. The factory has formed a series of production, with a total of eight specifications diameter: 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. The diaphragm pump uses nitrile rubber, neoprene rubber, fluororubber, and polytetrafluoroethylene according to different liquid media. To meet the needs of different users. Since its inception, the pump has been used by more than 1,000 domestic petroleum, chemical, electronics, ceramics, textile, paint, and pharmaceutical machinery systems. It is placed in special occasions to pump media that cannot be pumped by conventional pumps. And the ideal product to replace the gear pump, has taken a satisfactory result.

Main features of pneumatic diaphragm pump

1, no need to irrigate water, suction up to 7m, lift up to 50m, outlet pressure ≥ 6kgf / cm2;

2, the flow is spacious, the pass performance is good, allowing the diameter of large particles to reach 10mm. When pumping mud and impurities, the pump wears little;

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

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

5. It is not necessary to use electricity, and it is safe and reliable to use in flammable and explosive places;

6, can be submerged in the medium to work;

7. It is convenient in function and reliable in operation. It only needs to open and close the gas valve simply and openly. Even if there is no medium running or sudden stop due to unexpected conditions, the pump will not be damaged. If it is overloaded, the pump will automatically Ground stop, self-protection performance, when the load returns to normal, there is automatic start-up operation;

8. Simple structure and less wearing parts. The pump structure is simple to install and easy to maintain. The medium to be pumped will not touch the valve, the connecting rod and other moving parts, unlike other types of pumps due to the rotor, piston, gear, The wear of the blades and other components causes the performance to gradually decrease;

9, can transport a more viscous liquid (viscosity below 10,000 centipoise);

10. The pump does not need to be lubricated with oil. Even if it is idling, it has no effect on the pump. This is a major feature of the pump.

The rubber diaphragm is molded from natural rubber, and artificial additives are added to the rubber to improve the chemical resistance and bending properties of the separator.



In the compression of the rubber diaphragm, a nylon woven mesh is placed in the rubber to disperse the stress and strengthen the diaphragm.

Neoprene... an inexpensive common diaphragm for non-corrosive liquids.

Buna-U is a cheap enamel film for petroleum/oil-based liquids.

3 Dollars Rubber... has a good bending life at extremely low temperatures.

Fluorinated rubber (Viton)... has a good bending life at very high temperatures for the transport of aromatic or chlorinated hydrocarbons and acidic liquids.

PTFE F46 (Teflon Teflon)

Teflon is a synthetic material that is considered to be chemically stable. The Teflon diaphragm manufactured by Yangzijiang Pump Co., Ltd. has reinforcing ribs to control the curved shape of the diaphragm to extend its life. The innovations in this Teflon diaphragm have increased cost performance while greatly expanding the range of applications for diaphragm pumps. Teflon is not an elastic material and has no elasticity, so there is a support diaphragm to provide support and extend life.

In the two symmetrical various chambers of the pump, each is equipped with a flexible diaphragm 6, which is formed by integrating the two diaphragms, and the compressed air enters the valve 3 from the intake joint 1 of the pump, and pushes the two. The diaphragm in the working chamber drives the two diaphragms connected by the link to move synchronously. At the same time, the gas in the other working chamber is discharged from the back of the diaphragm to the outside of the pump; once the end of the stroke is reached, the valve train automatically introduces the compressed air into the other working chamber, pushing the diaphragm to move in the opposite direction, thus A synchronous reciprocating motion of the two diaphragms is formed. In each working chamber, two one-way ball valves 4 are arranged, and the reciprocating motion of the diaphragm causes a change in the inner volume of the working chamber, forcing the two one-way ball valves to be alternately opened and closed, thereby continuously sucking in and discharging the liquid.
