Jabsco Par-Max Water System Pump GPM

The Jabsco Par-Max water system pump (also called a fresh water pressure pump or automatic water pressure pump) is a self-priming, on-demand diaphragm pump. It gives boats, RVs and other vessels with pressurized fresh water a smooth, steady supply. When a faucet or fixture opens, the pump starts. When the fixture closes, the pump stops. That means water flows from the tank to the galley, lavatory, shower and other outlets with no extra effort.

Key Features:

• Self-priming design for flexible installation
• Dry-run capability, so the pump can run without water and not be damaged
• Multi-chamber diaphragm design for smooth flow
• Built-in bypass to reduce pulsation, cycling and noise. This can reduce or remove the need for an accumulator tank
• Integrated pressure switch for automatic, on-demand operation
• Quick-connect (snap-in) ports make installation, servicing and maintenance easier
• Vibration-dampening mounting feet for quieter operation
• Corrosion-resistant materials, including a co-molded or Santoprene-type diaphragm and EPDM check valves
• Designed to meet marine ignition-protection standards such as ISO 8846. Certifications vary by model.

Heavy-duty (HD) versions in the Par-Max line add a larger motor and a cast aluminum lower housing. These improve pressure capability and service life. The line is available in a range of flow rates, pressure settings and voltages to suit different water system needs.

Par-Max pumps are a dependable choice for replacing or upgrading an onboard fresh water system. They are quiet, simple to maintain, and built for the marine environment.
