Jabsco 12V Par Max 3 Pressure-Controlled Pump

The Jabsco 12V Par Max 3 Pressure-Controlled Pump is a compact and efficient solution for pressurised water systems on board small to medium-sized vessels. Designed to reliably serve two or more outlets, this pump is ideal for freshwater supply to galleys, heads, showers, and washbasins where consistent pressure, quiet operation, and dependable performance are essential.

Operating on a 12V DC power supply, the Par Max 3 delivers an open flow rate of up to 11 litres per minute, providing ample water flow for everyday onboard use without excessive power consumption. An integrated pressure switch controls pump operation automatically, cutting in at 1.4 bar (20 psi) and cutting out at 2.8 bar (40 psi). This pressure range ensures steady delivery while protecting plumbing components and connected appliances from unnecessary strain or pressure spikes.

The pump utilises an efficient multi-diaphragm design that combines durability with performance. This design allows the pump to self-prime up to a vertical lift of 1.8 metres, offering greater flexibility in installation, even when the pump is mounted above the water source. The diaphragm construction also enables the pump to run dry without damage, providing an added layer of protection during intermittent use or in situations where the water supply is temporarily interrupted.

To enhance onboard comfort, the Par Max 3 includes an integrated bypass feature that smooths water flow and significantly reduces pump cycling. This results in quieter operation and a more consistent water stream at taps and fixtures. Quiet running is further supported by the pump’s efficient motor design, making it well suited to installations close to living spaces.

Installation is straightforward thanks to the supplied snap-in ports for 13mm (½”) bore hose connections and the included inlet strainer, which helps prevent debris from entering the pump and damaging internal components. The motor is protected by an automatic thermal overload cut-out, safeguarding the pump against overheating during extended operation. Additional snap-in ports are available for alternative plumbing configurations, including compatibility with Hep20 systems when used with the specified accessories.
