‌Stainless Steel Diaphragm Pumps are pump equipment powered by compressed air, suitable for various corrosive liquids, liquids with particles, high viscosity, volatile, flammable, and highly toxic liquids. The pump body is made of stainless steel, offering excellent corrosion resistance and meeting the needs of different users.‌

Operating Principle

The stainless steel diaphragm pump is powered by compressed air. Each of the pump's two symmetrical working chambers contains an elastic diaphragm, connected by a linkage. After the compressed air enters the valve, it drives the diaphragms in the two working chambers to move synchronously, continuously forcing the liquid to be inhaled and discharged. Each chamber is equipped with two one-way ball valves, and the reciprocating motion of the diaphragms alternately opens and closes the valves, thereby transporting the liquid.

Performance Features

High Corrosion Resistance: Made of stainless steel, it maintains stability when handling corrosive media such as acids, alkalis, and salts, suitable for various chemical processes.

Seal integrity: The diaphragm completely isolates the transmission medium from the pump's moving parts, preventing any leakage of the medium, making it suitable for transporting toxic, volatile, or corrosive substances.

Strong self-priming capability: Can start without priming water and reach a suction depth of several meters.

High conveying capacity: capable of transporting granulated liquids, high viscosity liquids, as well as volatile, flammable, and highly toxic liquids.

Simple structure and easy maintenance: No complex rotating parts or seals, making installation and repair convenient.

Operation Reliable: Equipped with self-protection features, it will not be damaged even after long-term operation without medium or sudden shutdowns. It will automatically shut down under overload and restart automatically once it恢复正常.

Application Scenarios

Stainless steel pneumatic diaphragm pumps are widely used in various fields:
