Features of stainless steel diaphragm pumps
The stainless steel diaphragm pump is improved on the basis of the QBY pneumatic diaphragm pump. It has a built-in air distribution valve, a simpler structure, a larger flow rate, a higher head, and a more stable performance. It integrates the advantages of self-priming pumps, submersible pumps, shielded pumps, slurry pumps, and impurity pumps. It is widely used in chemical, petroleum, pharmaceutical, mining, papermaking, cement plants, steel plants, power plants, coal processing and other industries.
Features of stainless steel diaphragm pumps
The stainless steel pneumatic diaphragm pump can not only transport fluids, but also transport dry powders, and can also transport some difficult-to-move media. It combines the advantages of self-priming pumps, submersible pumps, shielded pumps, slurry pumps, and impurity pumps.
1. No need to fill water, high suction range, up to 7m, head up to 70m, outlet pressure ≥0.8Mpa.
2. Wide flow channel, good passability, can pump large particles with a diameter of up to 9.4mm, and the pump will not wear much when handling slurry or impurities.
3. The head and flow can be adjusted by the air supply pressure (air pressure between 0.1-0.84Mpa).
4. Operating temperature range: 5-65℃; medium transport range (-20℃-150℃).
5. The pump has no rotating parts, and the diaphragm isolates the conveying medium from the moving parts and working medium of the pump to prevent leakage of the conveying medium. Therefore, when conveying toxic, volatile, and corrosive media, it will not cause environmental pollution or endanger personal safety.
6. No electricity is required, and it is safe and reliable to use in flammable and explosive environments.
7. It can be operated while immersed in the medium.
8. It is easy to use, reliable in operation, and simple to start and stop. Just open and close the air valve. Even if it runs for a long time without medium or suddenly stops due to unexpected circumstances, the pump will not be damaged. If overloaded, the pump will automatically shut down and has self-protection capabilities. When the load returns to normal, it will automatically restart.
9. Simple structure and easy replacement of easily worn parts. The pump has a simple structure and is easy to install and maintain, which ensures that the conveyed medium does not contact with moving parts such as distribution valves and connecting rods, unlike other types of pumps, which gradually deteriorate in performance due to wear of rotors, pistons, gears, blades, etc.
10. It can handle relatively viscous liquids (viscosity below 10,000 centipoise).
11. The pump does not require oil lubrication and is not affected even when running at no load, which is a major feature of the pump.
