Flojet Heavy Duty RV Water Pump w/Strainer - 12V - 4GPM - 50PSI - Q401V-117S-3A

Flojet Heavy Duty RV Water Pump with Strainer – 12V – 4 GPM – 50 PSI – Q401V-117S-3A

The Flojet Q401V-117S-3A Heavy Duty RV Water Pump is a robust 12-volt diaphragm pump designed for high-demand RV, camper, and marine freshwater systems. Delivering 4 gallons per minute (GPM) at 50 PSI, this pump provides consistent, on-demand water flow to multiple fixtures such as sinks, showers, and appliances simultaneously.

Equipped with an integrated strainer, the pump prevents debris from entering your plumbing system, protecting internal components and extending the pump’s service life. Its self-priming diaphragm design ensures reliable startup even when water tanks are positioned below the pump, and it can run dry briefly without damage, making it ideal for mobile and off-grid applications.

The built-in pressure switch activates the pump automatically when water is needed and shuts it off once pressure is restored, creating efficient, hands-free operation. Engineered with durable, corrosion-resistant materials and designed for quiet, smooth operation, the Q401V-117S-3A is a heavy-duty solution built to withstand the rigors of RV, marine, and outdoor environments.

Key Features

• High-Flow Output: Delivers 4.0 GPM (15.1 LPM) and 50 PSI, providing enough volume for multiple faucets and high-pressure showers at once.

• Quiet and Smooth: The five-chamber diaphragm design provides a more consistent flow and quieter operation compared to standard three-chamber pumps.

• Self-Priming & Safety: Capable of self-priming up to 8 vertical feet and features run-dry protection, ensuring the pump isn't damaged if the water tank runs empty.

• Complete Setup: Includes a 40-mesh quick-connect strainer to keep debris out of the pump and multiple snap-in port fittings for easy 1/2" plumbing connections.
