How Tapflo Diaphragm Pumps work

The Tapflo diaphragm pump is driven by compressed air. The two diaphragms, connected by a diaphragm shaft, are pushed back and forth by alternately pressurising the air chambers behind the diaphragms using an automatically cycling air valve system.

  • The Suction Cycle
  • Suction (1)
    One diaphragm creates a suction action when being pulled back from the housing.

    Discharge (2)
  • The other diaphragm simultaneously transmits the air pressure to the liquid in the housing, pushing it towards the discharge port.

    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 affect to the life of the diaphragms.
