Food Grade Honey Pump Pneumatic Diaphragm Pump Sanitary Pump
Stainless Steel Beverage Pump
QBW sanitary liquid trasfer air operate diaphragm pump has excellent hygienic performance and can satisfy food and pharmaceuticals high-level health work needs.It also has the advantages of no sealing, easy maintenance, low shear, explosion-proof, idling, light weight, self-priming and so on.
A flexible diaphragm is installed in each of the symmetrical
working chambers of the hygienic diaphragm pump. The connecting rod
connects the two diaphragms together. After the compressed air
enters the valve chamber from the intake joint of the pump, the
diaphragm in the two working chambers is pushed forward.
Synchronized motion of diaphragm driven by connecting rod. At the
same time, the gas in another working chamber is discharged from
the back of its diaphragm to the outside of pump. When the piston
reaches the end of the stroke, the valve mechanism automatically
introduces compressed air into another working chamber, pushing the
diaphragm pump to move backwards, thus forming a synchronous
reciprocating motion of the two diaphragms. Two one-way ball valves
are installed in each working chamber. The reciprocating motion of
the diaphragm results in the change of the volume of the working
chamber. The two one-way ball valves are opened and closed
alternately, so that the liquid can be continuously inhaled and
1. Using precision casting, the surface is smooth and tidy, and has
a higher strength.
2. The integrated design of the diaphragm retaining block has
excellent pressure resistance and high temperature resistance and
is widely used in the filter press industry.
3. Three-section upper and lower cover, flexible installation.
4. Accurately calculate the moving distance of the diaphragm,
reduce the force of the diaphragm, and have a longer service life.
5. The diaphragm connecting rod is made of wear-resistant stainless
steel, which has better corrosion resistance and longer life.
6. The valve ball is further ground by a special machine, which has
high roundness and good sealing performance.
7. four bolt connection design, good sealing performance, the
actual dry suction can reach 3-7 meters.
