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, but also can convey some uneasy flowed medium, with the merits of self priming pump, slurry pump and impurity pump, etc.

Pump Spare Parts
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.
Application
1.The pump can suck the peanut, pickles, tomato slurry, red sausage, chocolate, hops and syrup etc.
2. The pump can suck the paint, pigment, glue and adhesive etc.
3. The pump can suck various glazed slurries of tile, porcelain, brick and chinaware etc.
4. The pump can suck various grinding materials, corrosive agent and clean the oil dirt etc.
5. The pump can suck various toxin and flammable or volatility liquid etc.
6. The pump can suck various wedge water, cement slurry and mortar etc.
7. The pump can suck various strong acid, alkali and corrosive liquid etc.
8. It can be used as a front-step transmission device of the solid and liquid separation equipment.
9. 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.
