Pressure Switch for Seaflo Diaphragm Pumps

These Seaflo Pressure switches are direct replacement for Seaflo 31/32/33/35/42/51/52 Series Diaphragm pumps.

Please check whether your pump's pressure switch is attached with either 2, 3 or 4 screws. They are different models.

Seaflo pressure switches are easy to remove and install.

Wires are removed by gently levering off the two (2) female blade terminals with a small flat bladed scew driver.

Please note: the wire colours must be re-attached identically to the original installation.

There is an Hex Head screw in the centre of the Pressure Switch.

1. Turning anti-clockwise half a turn will decrease pressure – increases cycling
2. Turning clockwise half a turn will increase pressure – reduces cycling
