GROCO Paragon Senior 24V Water Pressure System

The GROCO Paragon Senior 24V Water Pressure System is a marine-grade pressurized water supply solution engineered for large sailing yachts and expedition vessels over 50 feet in length. This 24-volt DC system delivers consistent water pressure up to 11 gallons per minute across the operating range of 30–50 PSI, making it ideal for vessels where traditional gravity-fed systems fall short or where reliable freshwater distribution is critical to extended cruising operations.

Built in the USA and NSF-61 certified for low-lead compliance, this system incorporates a powerful two-stage rotary pump that handles the demands of full-service water systems aboard offshore vessels. The patented NOFLOW™ dry-run protection automatically safeguards the pump if the water supply is exhausted, eliminating damage from cavitation—a critical feature for cruising boats that rely on limited water reserves. The included pressure gauge and inlet strainer provide visibility into system performance and protect internal components from debris. Compatible with GROCO PST-2, PST-3, PST-4, and PST-5 pressure storage tanks, the Paragon Senior integrates seamlessly into modular water systems common on performance cruising and blue-water yachts. Both 24V DC and AC models are available to match vessel electrical infrastructure.

This system is specified by cruising sailors, liveaboard operators, and marine systems integrators who demand reliability in remote conditions where service options are unavailable. The combination of proven rotary pump technology, dry-run protection, and NSF-61 certification positions the Paragon Senior as the preferred choice for serious offshore water systems where performance and durability directly impact vessel habitability and safety.

GROCO water systems are recognized across the marine industry for their engineering focus on reliability without unnecessary complexity. The Paragon Senior 24V Water Pressure System reflects that philosophy—delivering essential pressurized water functionality that seasoned cruising crews depend on during extended passages and anchorage stays.
