Stainless Steel 0.55kW–22kW pneumatic diaphragm pumps are available in pneumatic and pneumatic-electric types, with various power and flow specifications. They are commonly made of 304 and 316L stainless steel and feature explosion-proof safety, corrosion resistance, stable delivery, and strong adaptability.
Stainless Steel 0.55kW–22kW pneumatic diaphragm pumps are dual-purpose pneumatic/electric pumps. Driven by compressed air or an electric motor, the air distribution system causes the diaphragm to reciprocate. This diaphragm movement results in periodic changes in the pump chamber volume, allowing for the intake and discharge of the medium via a check valve. The medium is completely isolated from the drive components, effectively preventing leakage and ensuring safe operation. With a power range from 0.55kW to 22kW, they can meet various flow and pressure requirements and are suitable for corrosive, high-viscosity, or particulate media, operating stably in the chemical, environmental, and food industries.

Low pressure pneumatic operation ensures safe, stable pumping performance, reducing the risk of leakage and making the pump suitable for sensitive and hygienic fluid transfer applications.
Tri-Clamp sanitary connections allow quick installation, easy disassembly, and efficient cleaning, supporting frequent maintenance and compliance with hygienic processing requirements.
Stainless steel pump body provides excellent corrosion resistance, mechanical strength, and long service life in food, beverage, pharmaceutical, and chemical environments.
Diaphragm-driven structure isolates the fluid from air and moving parts, preventing contamination and enabling reliable handling of low-pressure or delicate media.
Stainless Steel 0.55kW–22kW pneumatic diaphragm pumps are widely used in the chemical industry for conveying acidic and alkaline liquids and solvents, in the food and beverage industry for conveying slurries, syrups and juices, in the pharmaceutical industry for transferring liquid raw materials and intermediates, and in environmental protection and water treatment systems for conveying sewage or suspensions.
