Jabsco Par-Max 3 Water Pressure Pump - 12V - 3 GPM - 25 PSI

The Jabsco Par-Max 3 Water Pressure Pump – 12V – 3 GPM – 25 PSI is a compact, self-priming water transfer system designed for mobile tactical, emergency response, and field operations where reliable pressurized water supply is essential. Whether deployed for decontamination protocols, portable washing stations, or emergency water systems on vehicles and remote installations, this 12-volt pump delivers consistent performance in demanding environments. Built by Jabsco, a manufacturer with deep roots in marine and industrial-grade fluid handling, the Par-Max 3 addresses the need for lightweight, durable pressure delivery without external power infrastructure.

The pump operates at 3 gallons per minute (GPM) flow rate with a maximum pressure rating of 25 PSI, ideal for low-pressure wash-down applications, spray systems, and gravity-fed tank supply. Heavy-duty construction includes a wider-diameter motor, powder-coated steel shell, and cast aluminum endbells and lower housing that enhance pressure capability and extend service life in corrosive or abrasive field conditions. The 12-volt DC power requirement makes integration straightforward on vehicles, mobile command units, or battery-backed portable systems. Weighing only 4.85 pounds and measuring 6 x 6 x 16 inches, the compact form factor fits tight mounting spaces without sacrificing flow or reliability.

Tactical teams, emergency services, hazmat units, and military field operations benefit most from this self-priming design, which eliminates the need for manual priming at each deployment. Installers should verify 12-volt DC availability—either from vehicle auxiliary power, portable battery systems, or solar-charged banks—and confirm water source elevation to optimize self-priming performance. Suitable for fresh or lightly brackish water applications, the pump pairs well with portable tanks, gravity-fed containers, or vehicle-mounted reservoir systems in forward-deployed or austere environments where conventional pressurized water infrastructure is unavailable.
