ECO-WORTHY 33-Series 110V Diaphragm Pump – 4.0 GPM, 50 PSI for RVs & Marine

Meet the ECO-WORTHY 33-Series Industrial Water Pressure Pump, a compact 110V diaphragm pump designed to deliver dependable water flow where you need it most. Built for mobile lifestyles and fixed setups alike, this unit blends practical power with quiet, on-demand performance. With a rated 4.0 GPM flow at 50 PSI, it provides a steady stream that supports everyday tasks from rinsing to refilling, without heavy gear or frequent battery swaps.

The pump operates from standard AC power, so you won’t have to depend on a marine battery in many configurations. An integrated smart pressure switch turns the pump on when you open a faucet and shuts it off as you close, helping to conserve energy and reduce noise. You can fine-tune the delivery with an adjustable pressure range of 45–70 PSI, allowing you to tailor the flow to your specific needs and fixtures.

Smart, on-demand pressure for real-life use

Quiet during operation, the switch responds to demand with a smooth start and stop. This makes it suitable for intermittent use on a campground hose, a boat’s water system, or a garden irrigation setup where steady pressure matters but noise or power waste should stay in check.

• 4.0 GPM at 50 PSI for reliable hand-wash, rinse, and refill tasks
• Adjustable 45–70 PSI to suit faucets, sprinklers, and hose outlets
• 110V AC power eliminates the need for carrying extra batteries in most setups

Reliable performance and safety you can count on

Self-priming up to 9.8 vertical feet and lifting capability up to 131 feet make it versatile for varied installations, from low-water RV compartments to higher garden taps. Thermal overload protection helps guard the motor; if temperatures rise to 95°C, the circuit disconnects automatically to prevent damage.

• Self-priming up to 9.8 ft and lift up to 131 ft for flexible placement
• Thermal protection to help guard the motor during extended use
• Continuous operation capable for longer tasks like irrigation cycles

Multipurpose by design

From RV freshness to boat-ready water systems and garden irrigation, this pump handles diverse scenarios. It works with a range of fixtures, including sprinklers and faucets, and is designed to perform reliably in mixed environments. A compact form factor makes installation straightforward, with a kit that includes garden hose adapters for easy setup and compatibility with standard hoses.
