Jabsco Par Max 3 Water Pump

The Jabsco Par Max 3 is a pressure-controlled fresh water pump with multiple diaphragms for self-priming and efficient pump action can run dry without damage and runs quietly with automatic thermal overload cut-out protection, ensuring the pump does not get damaged from overrunning.

The built-in pressure switch cuts in at 1bar (15psi) and cuts out at 1.7bar (25psi) producing an efficient, high-flow, self-priming water pump that can supply two or more outlets.

Jabsco Par-Max 3 pressure-controlled pump has a multiple diaphragm design which allows the pump to self-prime to 1.8m vertical lift has an output of 11 litres per minute (3 gallons per minute) with a maximum current of 5.2 amp.

When Should I Install a Pressure Water Pump?

If you wish to have water coming from your tap or shower when you turn the knobs as you would at home then a pressure controlled water pump is the answer. By opening the tap the pressure reduces and the pump starts pumping the water.

Installing the Jabsco Par Max 3

The pump can be positioned either horizontally or vertically (with the pump head at the bottom and the motor at the top). It comes complete with approximately 30cm of attached cable (14 AWG / 2.5mm²) which can be extended with suitable cable depending on the length.

Connection to the pump is easy, either directly through the supplied 13mm (1/2") hose connectors or through Hep20 push-fit connectors (not supplied). A push-clip inline filter is also supplied.
