The Jabsco Par Max HD4 Q401J-112S-3A is a powerful 12V self-priming water pressure pump, engineered for high-demand marine applications. With a flow rate of 15.1 LPM (4.0 GPM), this multi-diaphragm pump is ideal for boats with four or more outlets, including galleys, showers, livewells, and washdown systems.
Built for durability and versatility, the HD4 features a reinforced polypropylene housing, cast aluminium lower body, and EPDM diaphragms. It primes up to 2.4 metres (7.9 feet) vertical lift and runs dry without damage. The built-in bypass and pressure switch help maintain steady water flow and minimise pump cycling.
Supplied with a 40 mesh inline strainer and quick-connect fittings, this unit replaces multiple legacy Jabsco pumps, including models 31620‐0292, 32600‐0092, and 82600‐0392.
