Overview of QBK Pneumatic Diaphragm Pump:

QBK pneumatic diaphragm pump is the third generation pneumatic diaphragm pump developed by our company, which has the advantages of long service life, no stopping, and never crashing. It can pump flowing liquids and transport some difficult to flow media, and has many advantages of conveying machinery such as self-priming pumps, submersible pumps, shield pumps, mud pumps, and impurity pumps.
1. No need for water injection. The suction lift can reach up to 5m, the head can reach 70m, and the outlet pressure is ≥ 6bar.
2. Spacious flow and good performance. It allows particles with a diameter of up to 10mm to pass through. When pumping mud and impurities, there is minimal wear on the pump;
3. The head and flow 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 and no shaft seal. The diaphragm completely separates the pumped medium from the moving parts and workpiece medium of the pump, and the conveyed medium will not leak outward. So when pumping toxic, easily reactive or corrosive media, it will not cause environmental pollution and endanger personal safety;
5. No need for electricity, safe and reliable to 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. 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 automatically start and run 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):
1. This pump does not require oil lubrication and has no impact on the pump even when idling. This is the characteristic of this pump.
