Groco PJR-A 24V Paragon Junior 7 GPM Water Pressure System
The Groco PJR-A 24V Paragon Junior Water Pressure System is designed to deliver dependable freshwater pressure for yachts and vessels up to 50 feet in length. Built with a powerful two-stage rotary pump and paired with the PST-1 pressure storage tank, this system provides smooth and consistent water flow for sinks, showers, washdowns, and onboard plumbing systems. With a maximum flow rate of 7 GPM and operating pressure between 20 and 40 PSI, it delivers strong performance while reducing pump cycling and pressure fluctuations.
This 24V marine water pressure system includes GROCO’s patented NOFLO dry-run protection technology to help safeguard the pump during low-water conditions. The included pressure gauge and inlet strainer support easier monitoring and maintenance, while the self-priming design simplifies installation and operation in a wide range of marine applications. Its NSF-61 compliant low-lead construction also makes it suitable for potable water systems.
Engineered for durability and long-term reliability, the Groco PJR-A 24V system is ideal for recreational yachts, sport fishing boats, cruising vessels, and commercial marine freshwater systems that require steady water delivery and reduced wear on pump components.

FAQ Section
What makes the PST-1 tank beneficial in a marine water system?
The PST-1 pressure storage tank helps maintain steady water pressure throughout the vessel while minimizing rapid pump cycling. This improves comfort at faucets and showers while extending pump life.
Can this system be used with both fresh and salt water?
The system is primarily intended for onboard freshwater pressure applications, but certain compatible components can support additional marine plumbing uses depending on installation requirements.
Is the Groco PJR-A 24V suitable for multi-fixture boats?
Yes. The high-flow 7 GPM design supports multiple fixtures operating simultaneously, making it ideal for yachts with sinks, showers, and washdown stations.
Does the system require a separate accumulator tank?
No. The PJR-A 24V package already includes the PST-1 pressure storage tank for complete water pressure system operation.
Where should the pump system be installed?
The pump should be installed in a dry, ventilated location with reinforced plumbing connections to ensure optimal performance and long service life.
