Mini Stainless Steel Air Diaphragm Pump

Product Specification

QBY3 stainless steel air pneumatic diaphragm pump

DESCRIPTION

Pneumatic diaphragm pump is a new type of conveying machinery that uses compressed air as the power source. For various corrosive liquids, liquids with particles, high viscosity, volatile, flammable, and highly toxic liquids, it can be pumped and absorbed completely.
There are four types of materials for pneumatic diaphragm pumps: engineering plastic, aluminum alloy, stainless steel, and cast iron. The pneumatic diaphragm pump adopts Nitrile rubber, Neoprene, fluororubber, polytetrafluoroethylene, polytetrafluoroethylene, etc. according to different liquid media to meet the needs of different users. It is installed in various special occasions to pump various media that cannot be pumped by conventional pumps, and has achieved satisfactory results.

FEATURES

1. No need water supply, the suction lift is up to 5 meters, the head is up to 84 meters, and the outlet pressure is > 7bar;

2. Smooth and wide inner pipeline, can transfer the diameter of larger particles with diameter reach 10 mm. When pumping mud or impurities, it is nearly no wear of the pump;

3. The head and flow rate can be stepless adjusted through the opening of the air valve (air pressure adjustment is between 1-7bar);

4. The pump has no rotating parts, no shaft seal, and diaphragm and other mechanical parts are separated from the medium, so the transported medium will not leak. Therefore, it is suitable of pumping toxic, aggressive, or corrosive fluids, it is safe for environment and workers;

5. No need to use electricity, safe and reliable to be used in flammable and explosive places;

6. Can be used as a submersible pump;

7. Easy to use, starting or stopping the pump is simply by open and close the gas valve. Even if dry run for a long time in unexpected circumstances or sudden shutdown, the pump will not be damaged, once overloaded, the pump will automatically stop by self-protection, when the load returns to normal, and it can automatically restart;

8. Compact structure, less wore parts, the pump is easy to install and maintain, the medium transported by the pump will not contact the gas distribution valve, coupling rod and other moving parts, so the wear of rotors, pistons, gears, blades, and other components has been reduced;

9. Can transport high viscous liquids (viscosity below 10,000 cP);

10. No need to be lubricated with oil, and can dry run.

The working principle of the pneumatic diaphragm pump is a positive displacement Reciprocating pump that uses the air compressor to input compressed air into the distribution valve of the diaphragm pump to drive the link shaft in the middle body of the diaphragm pump to drive the diaphragm pump diaphragm in the medium chamber of the diaphragm pump body to make transverse stretching movement to achieve the function of self-priming fluid. In the two symmetrical working chambers of the pump, each is equipped with an elastic diaphragm. The connecting rod connects the two diaphragms into one body, and compressed air enters the distribution valve from the inlet joint of the pump to push the diaphragms in the two working chambers, driving the two diaphragms connected by the connecting rod to move synchronously. At the same time, the gas in the other working chamber is discharged from the pump behind the diaphragm. The pneumatic diaphragm pump consists of two main parts: an airflow structure and a liquid flow structure, which are completely isolated by the two diaphragms on both sides.

The air supply pressure only needs to be greater than two kilograms per square centimeter to work. At a working pressure of 5 to 8 kilograms, the high-pressure gas in the valve chamber drives the connecting rod shaft to move back and forth through the airflow guidance system. At the same time, the consumed low-pressure gas is quickly discharged through the exhaust port. Under the alternating action of high and low pressure gases on both sides, the connecting rod shaft drives the diaphragms on both sides to move left and right, causing alternating changes in the air pressure in the volume chambers on both sides, thereby achieving continuous suction and discharge of liquid.
