Product Overview
The QBY3 pneumatic diaphragm pump uses compressed air as its power source and is a type of volumetric pump that undergoes volume changes due to the reciprocating deformation of the diaphragm. It has six major advantages, including reliable quality, long service life, low noise, small vibration, no freezing, and fine workmanship. It can not only pump flowing liquids, but also transport some media that are not easy to flow. It has many advantages of conveying machinery such as self-priming pumps, submersible pumps, shield pumps, mud pumps, and impurity pumps.
Product Features
1. No need for water injection, with a suction height of up to 5 meters, a lift of 70 meters, and an outlet pressure of ≥ 7 bar;
2. The flow is spacious and has good performance, allowing particles with a diameter of up to 10 millimeters to pass through. When pumping mud and impurities, there is minimal wear on the pump;
3. The head and flow rate can be infinitely adjusted through the opening of the air valve (the air pressure can be adjusted between 1-7 bar);
4. The pump has no rotating parts, shaft seals, diaphragms, etc. The pumped medium is completely separated from the moving parts and workpiece medium of the pump, and the conveyed medium will not leak outward. So when pumping toxic, volatile or corrosive media, it will not cause environmental pollution and endanger personal safety;
5. No need for electricity, safe and reliable use in flammable and explosive places;
6. Can work submerged in a medium;
7. Easy to use, reliable in operation, with simple opening and closing of the gas valve for on-off operation. Even if the pump runs without medium for a long time or suddenly stops due to unexpected situations, it will not be damaged. Once overloaded, the pump will automatically stop, with self-protection performance. When the load returns to normal, it can start running automatically again;
8. The pump has a simple structure and few vulnerable parts. It is easy to install and maintain, and the medium transported by the pump does not come into contact with moving parts such as the valve and connecting rod. Unlike other types of pumps, the performance gradually decreases due to wear and tear of components such as rotors, pistons, gears, and blades;
9. Can transport viscous liquids (viscosity below 10000 centipoise);
10. This pump does not require oil lubrication and has no impact on the pump even when idling, which is a major feature of the pump;
11. Plastic flange pressure: PN0.6MPa (10bar), metal flange pressure: PN1.0MPa (10bar).
