Kohree 110V On-Demand Water Pump — 4 GPM at 50 PSI, Self-Priming Diaphragm Pump

Meet the Kohree 110V AC Water Pressure Pump, built to deliver steady, dependable fresh water flow when you need it most. Whether you’re on the road in an RV, aboard a boat, or maintaining water pressure for a garden or home setup, this pump is designed to keep taps flowing with consistency and ease.

At its core, the pump provides 4.0 GPM at 50 PSI, helping to minimize cycling and maintain a reliable pressure across sinks, showers, and faucets. The self-priming diaphragm mechanism can prime up to 9.8 vertical feet and lift water up to 148 feet, giving you installation flexibility from shallow tanks to longer hose runs.

On-Demand Control with Adjustable Performance

The integrated pressure switch activates on water demand and stops when not needed, promoting energy efficiency and motor longevity. You can fine-tune the output with an adjustable PSI range from 40 to 70, making it suitable for RVs, boats, cabins, and off-grid setups.

Quiet, Durable Operation

A heavy-duty, corrosion-resistant motor paired with a rubber mounting base minimizes vibration and sound, helping to keep living spaces comfortable. Thermal overload protection adds an extra layer of safety, helping prevent damage from dry running and heat buildup.

Versatile, All-In-One Kit

This Kohree pump is designed for a wide range of applications—including RVs, campers, yachts, irrigation, and household faucets. The complete kit supports quick, plug-and-play setup, so you can start using your system with minimal tools.
