Hesaide pneumatic diaphragm pump is a kind of new type conveying machinery. It adopts compressed air as power source. It is applicable to corrosive liquid, liquid with particles and liquid which is highly vicious, volatile, flammable and hypertoxic. This pump is widely used in chemical industry, pharmacy, brewing, papermaking, food and other industries.
Core parameters
Suction Length: 5-7 m
Flow Rate: 0.8-30 m³/h
Hesaide Pneumatic Diaphragm Pump – Technical Specifications
The Hesaide QBY Series Pneumatic Diaphragm Pump is a versatile, air-powered pump designed for handling corrosive, abrasive, viscous, volatile, flammable, and toxic liquids. It requires no priming and can efficiently transfer both free-flowing and thick fluids with suction lift up to 2.7m and discharge head up to 50m.
✔ No Priming Required – Self-priming capability
✔ Explosion-Proof – Safe for flammable & hazardous liquids
✔ Dry-Run Capable – No damage if run dry
✔ Adjustable Flow & Pressure – Control via air pressure (0.1 MPa min.)
✔ Handles Solids & Slurries – Up to 80% solid content (depending on model)
