Food Grade Honey Pump Pneumatic Diaphragm Pump Sanitary Pump Stainless Steel Beverage Pump

Brief introduction

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.

Working principle:

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 discharged.


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.
