Water Pressure Systems

Marine Water Pressure Systems for Recreational Marine Applications

When you're at sea, performance matters—especially when it comes to your freshwater system. Marine water pressure systems ensure a steady, reliable flow for onboard faucets, showers, and galley appliances, all while withstanding the harsh marine environment. Whether you’re building, refitting, or upgrading, choosing the right marine water pressure system can significantly impact comfort, convenience, and functionality onboard.

At Johnson Pump Marine, we understand the demands of life on the water. That’s why our Aqua Jet™ water pressure systems are engineered specifically for marine applications. With dramatically lower noise and water pulsation characteristics and self-priming capabilities, these systems are as efficient as they are quiet—ideal for recreational boats of any size.

What sets us apart? Our line of Aqua Jet™ pumps, including the WPS 2.4 through 5.2 series, the Aqua Jet Flow Master WPS 5.0 with variable flow, and compact all-in-one units, offers flexible solutions to meet the needs of naval architects, marine engineers, and boat owners alike. Whether you need a marine fresh water accumulator tank or a compact pump system, we’ve got the answer.
