The Jabsco Par-Max HD5 Heavy Duty Water Pressure Pump delivers 5 GPM at up to 40 PSI from a compact 12V unit built for boats, RVs, and other high-demand water systems where consistent pressure and durability matter.
-
Rugged Construction: Wider-diameter motor with powder-coated shell, cast aluminum end bells, and lower housing to handle high pressures and extend service life.
-
Performance Specs: 12V DC operation provides 5 GPM flow at 40 PSI discharge while the integrated bypass module reduces pump cycling for steadier output.
-
Diaphragm Technology: Co-molded TPV diaphragm combined with EPDM check valves and glass-fiber-reinforced polypropylene upper housing delivers reliable, long-life pumping in a compact package.
-
Quiet Operation: Vibration-dampening mounting feet and built-in bypass minimize noise and smooth water delivery to multiple outlets such as showers and sinks.
-
Self-Priming Design: Primes up to 7 ft (2.13 m) dry, runs dry without damage, and accepts up to 30 PSI inlet pressure for flexible system placement.
-
Installation and Protection: Quick-connect ports speed setup and maintenance; plastic motor housing plus IPX6 rating, CE, ISO8846, and RCM certifications guard against corrosion and harsh environments.
Users gain a steady multi-outlet water supply that reduces annoying cycling and motor noise while surviving marine or mobile conditions without extra guarding. The self-priming capability and quick-connect ports let installers position the pump conveniently and service it quickly, keeping downtime low in demanding applications.
