Jabsco Par-Max HD4 Heavy Duty Water Pressure Pump - 24V - 4 GPM - 60 PSI

Jabsco Par-Max HD4 Heavy Duty Water Pressure Pump — a rugged 24V system delivering reliable, high-flow water pressure for marine, RV, and other demanding applications. This model provides 4 GPM at 60 PSI, making it ideal for vessels with multiple outlets and on-demand water needs.

HD (Heavy Duty) models feature a wider diameter motor with a powder-coated shell, plus cast aluminum endbells and a lower housing to improve pressure capability and life. Available in configurations up to 6 GPM (23 LPM) and 60 PSI (4.1 BAR), these pumps deliver exceptional performance. Standard models provide good performance in an economical footprint and are available in 1-3 GPM for vessels with fewer outlets. A plastic housing protects the motors from corrosion.
