[SAFETY and EXPLOSION-PROOF] The operating pressure is between 1~8.3 bar, driven by air pressure. A Pneumatic Double Membrane Pump can dry-run for extended periods of time without getting overheated. Blocked suction or discharge pipework, the pump will stop due to air pressure balance, and the pipeline pressure will not continue to rise, not causing the danger of pipeline rupture and liquid leakage..
[AODD PUMP CAN HANDLE A WIDE RANGE OF PH LEVELS] The pneumatic diaphragm pump design isolates the conveyed fluid from the pumping chamber. Diaphragm Pump is ideal for pumping highly corrosive and hazardous chemical fluids and volatile. Normal operation will not cause harm to the environment and operators..
[Wide Applications] The diaphragm pump is suitable for almost of fluids. Pumps can be widely used in the automation industry, water treatment, mining, petroleum, oil and gas, coating, printing, electroplating, chemical industry, electronics, construction, Pharmaceutical, metallurgy, and other industries..
