QBW Hygienic pneumatic diaphragm pump has the advantages of no sealing, explosion-proof, low shear, easy maintenance, idling, light weight, self-priming and so on. It also has excellent hygienic performance and can satisfy food and beverage and pharmaceuticals etc. high-level health work requirements.
Advantage:
1.The flow parts of QBW pneumatic diaphragm pump is made of stainless steel material (SS304, SS316,SS316L) with hygienic/sanitary food grade requirements.
2. Pump uses precision casting. The surface is smooth and tidy and has a higher strength.
3. Valve ball is further processed by a special machine, which has high roundness and good sealing performance.
4. Accurately calculate the moving distance of the diaphragm to reduce the force of the diaphragm and have a longer service life.
5. Four bolt connection design, good sealing performance, the actual dry suction can reach 0-4 meters.
6. Three-section upper and lower cover, flexible installation.
7. The integrated design of the diaphragm retaining block has excellent pressure resistance and high temperature resistance and is widely used in food, alcohol, daily chemical, beverage industry.
8. Connecting rod of the diaphragm is made of wear-resistant stainless steel, which has better corrosion resistance and longer life.
