Tapflo Air Operated Diaphragm (AOD) pumps are made from polyethylene (PE) or PTFE and are suitable for handling almost any kind of liquid whether it is viscous, chemically aggressive or contains solids.

Tapflo diaphragm pump is driven by compressed air. Two diaphragms are working simultaneously to prime and push the liquid through the pump system. Valve balls work as check valves to let the liquid through in the right direction. During each cycle the air pressure on the back of the discharging diaphragm is equal to the head pressure on the liquid side. Tapflo diaphragm pumps can therefore be operated against a closed discharge valve with no adverse effect to the life of the diaphragms.
