Zero Leak Air Operated Reciprocating Buna-N Diaphragm Pump
Introduction
QBK series pump is an air operated double diaphragm pump, which is driven by air. It is a kind of positive displacement pumps which volume changes caused by compressing diaphragms in both side. This pump not only can exhaust the flow liquid, it also widely used to chemical industrial, food grade industry.

Features
1. The air diaphragm pump has the function of self priming without rotating parts. It can achieve dry priming and wet priming, which self -priming height is 5m and 8m respectively.
2. With sectional type structure, this self -priming pump can be used for conveying two different liquid by double diaphragm.
3. Our pump can be used directly as a submersible pump, it uses air as the power source, and does not have the leakage and other security risks. This diaphragm pump has lower cost than submersible pump which is caused by the maintenance of motor.
4. Pumps provide stall-free, ice-free operation.
5. Bolt joint design provides even sealing pressure for optimal performance.
6. Diaphragm,ball and ball seat adopt imported materials with longer service life.
7. Due to their pneumatic motor, they could be used in potentially explosive areas.
8. Can pump corrosive , volatile, flammable, poisonous fluids with particles and high viscosity.
