Jabsco 24V 40psi Par Max HD 4′ Pressure-Controlled Pump

The Jabsco 24V 40psi Par Max HD 4′ Pressure-Controlled Pump is a compact yet powerful solution for pressurised water systems on board larger vessels requiring reliable performance across multiple outlets. Designed to efficiently serve four or more outlets, this pump delivers consistent water flow while maintaining controlled pressure, making it ideal for marine freshwater systems, galleys, heads, and washdown applications operating on 24V electrical systems.

This pump features an efficient multi-diaphragm design that provides an open flow rate of up to 16 litres per minute while regulating pressure through an integrated pressure switch. The system cuts in at 1.4 bar (20 psi) and cuts out at 2.8 bar (40 psi), ensuring smooth operation without pressure surges and eliminating the need for external regulators. This controlled cycling helps protect plumbing components while delivering dependable performance throughout the system.

Self-priming capability up to 1.5 metres allows for flexible installation, even when the pump is mounted above the water source. The diaphragm construction enables the pump to run dry without damage, providing additional protection during intermittent use or temporary water supply loss. Supplied snap-in ports for 13mm (½”) hose connections and an inlet strainer simplify installation and help prevent debris from entering the pump.

Built for durability in demanding marine environments, the Par Max HD range features a heavy-duty motor protected by an automatic thermal overload cut-out, preventing damage during extended or high-load operation. Cast aluminium lower housings enhance structural strength and heat dissipation, extending service life even when operating at higher pressures. Additional snap-in ports are available for alternative hose configurations, offering versatility across a range of onboard plumbing systems.
