Description

Johnson Pump Aqua Jet WPS 2.9 GPM – 12V – NPT – 2.8 Bar – 10-13405-103

The Johnson Pump Aqua Jet WPS 2.9 GPM Water Pressure Pump System is a compact, intelligent freshwater pressure solution designed for boats, RVs, and mobile water systems requiring quiet operation and consistent pressure. Operating on 12V DC, this system delivers up to 2.9 gallons per minute at 2.8 bar (approximately 40 PSI), making it ideal for supplying water to sinks, showers, and small onboard appliances.

Featuring variable-speed diaphragm pump technology, the Aqua Jet WPS automatically adjusts pump speed based on water demand, providing smooth, pulse-free water flow while reducing noise, vibration, and power consumption. The integrated electronic pressure control eliminates the need for an accumulator tank, simplifying installation and reducing system complexity.

Built with marine-grade materials and corrosion-resistant components, the Aqua Jet WPS is engineered for long service life in harsh environments. NPT threaded ports ensure easy integration with standard plumbing systems, making this unit a versatile choice for both new installations and system upgrades.

Key Features

• Five-Chamber Design: Delivers a consistent, pulsation-free flow that mimics a residential water system.

• Quiet Operation: Engineered with high-quality bearings and a balanced motor to minimize noise and vibration during use.

• Self-Priming: Capable of lifting water up to 8 vertical feet, allowing for flexible mounting locations above the water tank.

• Integrated Pressure Switch: Automatically turns the pump on when a faucet is opened and off when it’s closed, maintaining a steady 41 PSI (2.8 Bar).

• Run-Dry Capability: The durable construction allows the pump to run dry for short periods without damaging the internal diaphragms.
