GROCO Paragon Senior Water Pressure System - 115VAC

The GROCO Paragon Senior Water Pressure System 115VAC is a purpose-built marine water supply unit engineered for vessels 50 feet and larger that demand reliable, consistent pressure delivery. Rated at a maximum 11 gallons per minute with operating pressure maintained between 30–50 PSI, this system delivers the flow and pressure necessary for multi-station water distribution on larger yachts where gravity-fed systems or undersized pumps create operational constraints.

Built around a powerful two-stage rotary pump, the Paragon Senior uses a 115VAC electrical supply for worldwide compatibility and minimal installation complexity. NSF-61 low-lead certification ensures water quality compliance with marine sanitation standards. The system includes an integrated 1-inch strainer to protect the pump from debris and sediment—critical on long-range passages where water source quality varies. The patented NOFLO dry-run protection prevents pump cavitation and damage when water supply is interrupted, a common concern in shifting sea states or when auxiliary tanks are exhausted before switch-over. A pressure gauge is included for real-time system monitoring; pressurization tanks (models PST-2, 3, 4, or 5) are ordered separately based on vessel size and water demand profile.

This unit serves cruising yachts, expedition support vessels, and larger commercial water-transfer applications where manual or low-capacity systems prove insufficient. The 40.3-pound assembly is designed for engine-room or utility-space mounting in compact marine installations. Operators familiar with marine systems will recognize GROCO's reputation for salt-air durability and service-friendly design—components are accessible for maintenance without full system disassembly.

Tank selection is critical to final performance; undersized accumulator tanks result in pressure cycling and pump short-cycling, reducing component life. Properly paired with an appropriately rated tank, the Paragon Senior delivers the steady pressure distribution required across multiple showers, heads, and deck-wash stations on larger vessels.
