Johnson Pumps 10-25011-03 Aqua Jet II Water Pressure Pump 5.2 GPM 12V 40 PSI

The Johnson Pumps Aqua Jet II (10-25011-03) is a self-priming, variable-speed freshwater pressure pump designed for marine, RV, and recreational vessel applications. Delivering 5.2 gallons per minute (GPM) at 12V DC with an automatic shutoff pressure of 40 PSI, this pump provides consistent, on-demand water pressure throughout the vessel's plumbing system.

The Aqua Jet II features an integrated pressure switch that automatically starts and stops the pump based on system demand, eliminating the need for a separate accumulator tank in many installations. Its compact, lightweight design allows for flexible mounting in tight engine rooms or storage compartments, while the corrosion-resistant housing stands up to the harsh marine environment.

Key Features:

• Flow Rate: 5.2 GPM for robust multi-fixture performance
• Operating Voltage: 12V DC
• Automatic Shutoff Pressure: 40 PSI
• Self-Priming: Capable of priming from dry with a vertical lift up to 8 feet
• Integrated Pressure Switch: Automatic start/stop based on demand — no separate pressure switch required
• Variable Speed Motor: Reduces cycling, minimizes pulsation, and extends pump life
• Corrosion-Resistant Construction: Built to withstand marine and outdoor environments
• Compact Design: Easy installation in space-constrained areas
• Quiet Operation: Smooth, low-noise performance suitable for live-aboard and overnight use

The Johnson Pumps Aqua Jet II is a trusted solution for boats, yachts, and RVs requiring reliable freshwater pressure. It is compatible with standard 1/2 in. and 3/4 in. plumbing fittings and is well-suited for systems serving two or more fixtures simultaneously.
