Working principle
The Tapflo electric diaphragm pump is driven by a gear-motor. In this type of pump there is a need to change rotary motion into reciprocating one. It is obtained by an eccentric shaft with a cam and piston. The rotary movement of the shaft (red part) is transferred to the reciprocating movement of the diaphragm shaft (yellow part).
Suction (chamber 1)
One diaphragm creates a suction action in one chamber (right side) when being pulled back from the housing.
Discharge (chamber 2)
The other diaphragm simultaneously transmits the air pressure to the liquid in the second chamber (left side) of the housing, pushing it towards the discharge port.

Options
Pressure switch
Device monitoring discharge pressure and protecting against closing of the discharge valve . This is for protection against excessive rise of the pressure on the wet side which could result in damage of the pump.
Inverter
Inverter allows full control over the operation of the pump by influencing motor speed. Changing motor speed affects capacity.
