The GROCO Paragon Senior 12V Water Pressure System (PWR 12V) is an industrial-grade, high-capacity water pressure system designed specifically for large yachts, typically over 50 feet in length. It is widely considered a marine industry standard for vessels requiring high flow and reliable pressure for multiple onboard outlets.

High-Performance Pumping

The system utilizes a powerful 2-stage rotary pump design that provides consistent water flow and pressure similar to a residential setting.

• High Flow Capacity: Delivers a maximum flow rate of 11 GPM, allowing for multiple showers, faucets, and appliances to run simultaneously without significant pressure drops.

• Operating Range: Maintains an adjustable pressure range between 30 and 50 PSI, ensuring strong and steady performance across the entire vessel.

• Self-Priming: The pump is self-priming up to 10 vertical feet, making installation flexible within the engine room or utility space.

Safety and Durability

Built with heavy-duty materials, this system is engineered to withstand the demanding marine environment.

• Dry-Run Protection: Features the patented NOFLO™ dry-run protection system, which automatically shuts down the pump if the water supply is interrupted, preventing motor damage.

• Corrosion-Resistant Build: Constructed from high-quality bronze and stainless steel, it is suitable for both fresh and saltwater applications.

• Compliance: Fully complies with the NSF-61 low-lead standard, making it safe for drinking water systems.

Installation Essentials

• Pressure Storage Tank required: This system must be used with an external pressure storage tank (such as the Groco PST-2, 3, 4, or 5) to prevent the pump from cycling too frequently.

• Electrical Requirements: Operates on 12V DC and requires a dedicated 50-amp circuit breaker.

• Included Accessories: The package typically includes an inlet strainer to protect the pump from debris and a pressure gauge for easy system monitoring.

Recommendation

The GROCO PWR 12V is the best choice for owners of large motor yachts or sailing vessels who need a commercial-grade freshwater system capable of handling high demand. Its ability to support multiple fixtures at once makes it superior to standard diaphragm-style pumps found on smaller boats.
