Introduction
Pneumatic diaphragm pumps use compressed air to drive the reciprocating motion of a diaphragm to transport liquids. They are suitable for transporting corrosive, high-viscosity, particulate, and flammable and explosive liquids, and are widely used in the chemical, environmental protection, food, and pharmaceutical industries.
Key features
Strong Corrosion Resistance
A fluororubber or PTFE diaphragm, combined with a pump body lining, ensures long-term resistance to strong acid and alkali corrosion.
Completely Isolate Structure
The dual-chamber diaphragm design eliminates mechanical connection between the air and liquid chambers, eliminating the risk of rotary shaft seal leakage.
Safe Operation
A built-in air valve automatically adjusts the air supply pressure to prevent damage to the diaphragm due to excessive air pressure.
Low Risk of Clogging
Wide inlet and outlet design reduces flow resistance.
Lubrication and Maintenance-Free
Purely pneumatically driven, no lubrication required, eliminating the risk of oil contamination.

FAQ
Q: What types of liquids can an Air Driven Diaphragm Pump pump handle?
A: It can handle highly corrosive, high-viscosity, particulate-laden, and flammable or explosive liquids.
Q: Will running the pump dry damage it?
A: No, the design allows for extended periods of dry running without damage.
Q: Will the pump leak?
A: No, the pump is completely isolated from the gas and liquid, preventing leakage.
Q: Does it require a power source?
A: No, it is driven entirely by compressed air.
Q: How often do the diaphragms need to be replaced?
A: Depending on the corrosiveness of the medium and the frequency of operation, they are typically replaced every six months to one year.
