Jabsco Par-Max HD3 Heavy Duty Water Pressure Pump - 12V - 3 GPM - 40 PSI

Meet the Jabsco Par-Max HD3 Heavy Duty Water Pressure Pump — a rugged 12V solution delivering 3 GPM at 40 PSI for reliable water pressure on boats, RVs, and other demanding installations. HD3 models feature a wider motor with a powder-coated shell, cast aluminum endbells and a reinforced lower housing to maximize pressure capability and extend service life.

Key advantages

• Heavy-duty build: Wider motor, powder-coated shell, cast aluminum endbells and lower housing for higher pressure and greater durability.
• Versatile performance: Configurations up to 6 GPM (23 LPM) and 60 PSI (4.1 BAR); standard models deliver economical performance for vessels with 1–3 outlets.
• Efficient and quiet: Co-molded diaphragm technology minimizes wear while the integrated bypass module delivers smoother flow and reduced cycling.
• On-demand and versatile: Integrated sealed pressure switch enables automatic operation, while self-priming allows flexible installation (dry-run capability up to 7 ft).
