Johnson Pumps Aqua Jet Water Pressure Pump GPM

The Johnson Pumps Aqua Jet water pressure pump (also called a fresh water pressure pump or WPS pump) supplies steady pressurized water to the faucets, showers and fixtures on small to medium-sized leisure and commercial boats, and on RVs and camper vans. Every pump in the line uses a five-chamber diaphragm design.

Key Features:

• Five-chamber, positive displacement diaphragm pump head: Runs quieter and pulses less than conventional three- and four-chamber diaphragm pumps, including at low speeds.
• Self-priming: Suits closed-system water pressurization.
• Integrated pressure switch: Turns the pump on when a tap is opened and off when it is closed.
• Dry-run capable: The pump can run dry without damage.
• Flexible connections: Quick-connect hose fittings or threaded connectors, depending on model.
• Durable construction: Thermoplastic body with Santoprene and EPDM diaphragm and valve components.
• Low-cost maintenance: Built for long service life and easy upkeep.

Johnson Pump recommends pairing the pump with an accumulator tank and fitting an inlet strainer ahead of the pump intake. This helps protect the pump and smooths water delivery. Johnson Pump is a well-known name in marine water systems. The Aqua Jet line gives boaters and RV owners a dependable pump for onboard water.
