Key components of the Tapflo diaphragm pump

Three major components are especially vital for the function of the pump.

Long life diaphragms

The two diaphragms are doing the work to prime and push the liquid through the pump system. Tapflo diaphragms are of sandwich compound construction, superior for continuous heavy duty service.

The solution with an integrated metal core, provides a completely smooth surface in contact with the liquid, without any nuts or washers. This results in no leak through and a diaphragm which is easy to keep clean.

The diaphragm is available in PTFE (food grade), EPDM, white EPDM (food grade), NBR and FKM (FKM on certain models only).

Pollution free air valve

The air valve is the driving heart of the pump, distributing the compressed air to the chambers behind the diaphragms.

It is made for maintenance free duty with no lube air, thanks to the ingenious sealing system. It will not only save your money for lubrication, it will also save your environment from pollution. 

The Tapflo air valve has no deadlock position – the pump will always start automatically when air is supplied to the pump. The valve body is made from brass or optional stainless steel AISI 316.

Ball check valves

The Tapflo pump is fitted with four check valves, making sure that the liquid is transferred in the right direction through the pump.
The valve is of ball valve type, the most simple and reliable valve design. It has a good sealing capability and is easy to keep clean and to replace if necessary.
The valve ball is available in EPDM, NBR (nitrile), PTFE, AISI 316, polyurethane and ceramic to suit any kind of liquid.
