Air Operated Diaphragm Pumps for Chemical



The usual applications of chemically resistant diaphragm pumps include, Transfer and dosing of chemicals and acids.

These air operated chemical pumps operate from compressed air and flow rates can be adjusted by controlling the air flow into the pump. You can also stop the pump by closing a valve on the discharge line without damaging the pump. Once the pressure builds up in the discharge line and meets the same pressure as the air compressor, the pump will stall. You can then open the valve and the pump will start.
