Jabsco Par Max 2 Water Pump

The Jabsco Par Max 2 is a pressure-controlled 12 volt fresh water pump with a marine protected motor, sealed pressure switch and co-injected moulded diaphragms for self-priming. All this makes for an efficient water pump that 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 out at 2.4bar (35psi) producing an efficient, high-flow, self-priming water pump that can supply four or more outlets.

The Jabsco Par Max 2 pressure controlled pump has a multiple diaphragm design which allows the pump to self-prime up to 1.8m vertical lift. It has an output of 7.6 litres per minute (2 gallons per minute) with a maximum current of 6 amps.

The boat water system pressure pump comes with quick-clip port terminals for the supplied 1/2" hose tail fitting, other fittings are available separately.

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.

Why Should I Buy a Jabsco Par Max 2

If you want a reliable, good value water pump then this Jabsco Par Max 2 is for you. It can supply a reasonable quantity of water to one or two outlets at the same time.

Installing the Jabsco Par Max 2

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.
