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

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.Beverage industry: peanut butter, pickled vegetable, mashed
tomato, samll sausage, jam, chocolate, flavor and fragrance, as
well as the hops, slurry of baking powder, syrup and molasses.
2.Paint industry: oil paint, gun, pigment, coating, etc.
3.Chemical industry: various kinds of emulsion, stuffing, rubber
slurry, abrasive material, corrosive, petroleum, mud, toxic,
inflammable and explosive liquid, and highly acidic, basic and
corrosive medium.
4.Adhesive and glue industry: all the liquids include in the
industry are available.
5.Ceramic industry: various kind of glaze slip for tile, porcelain,
brick and pottery.
6.Environmental protection and wastewater treatment industry: this
QBK air operated diaphargm pump can be matched with plate-and-frame
filter process for sewage treatment.
7.Mine industry: transportation of sediment and ponding in mine,
adit and tunnel, as well as the cement grouting and mortar.
8.Marine industry: sewage cleaning on oil tank and barge, and the
transportation of high temperature liquid. The maximum liquid
temperature can be 150ºC
