Kohree 12V RV Water Pump 5.5 GPM 55 PSI — Self-Priming Diaphragm, Thermal Protection

The Kohree 12V RV Water Pump is a self-priming diaphragm pump delivering up to 5.5 gallons per minute at a 55 PSI pressure switch for reliable on-demand water in RV, marine, and light-duty outdoor systems.

This compact 12-volt pump is engineered to supply consistent water pressure for faucets, showers and sinks in recreational vehicles and boats, while also serving garden watering and transfer tasks. Its self-priming design handles lifts up to 3 meters and features built-in safety measures—thermal overload protection and short run-dry tolerance—to reduce the risk of motor damage. The pump ships factory-tested and includes Teflon tape to help seal fittings and minimize leaks after installation.

How does this pump perform in an RV or boat plumbing system?

The Kohree pump maintains steady on-demand pressure suitable for typical RV and marine freshwater systems, automatically cycling to keep fixtures supplied. The 55 PSI pressure switch and open flow design work together to offer reliable stops and starts without surges.

• 5.5 gallons per minute flow rate for quick water delivery
• 55 PSI pressure switch set for household-style pressure
• Automatic start/stop control to reduce water hammer and cycling
• CE certified for compatible freshwater and marine installations

Can the Kohree 12V pump handle dry running and overheating?

Yes. The pump tolerates brief run-dry events and has thermal overload protection that stops the motor if temperatures rise too high. These features help protect the motor and extend service life when facing occasional low-water conditions or blockages.

• Short-duration run-dry tolerance to prevent immediate burnout
• Built-in thermal cutoff restarts only after safe temperatures are reached
• Lower maintenance risk compared with unprotected pumps
• Factory inspection reduces chance of early defects

What are the installation and leak-prevention details I should know?

The pump is shipped inspected and may retain residual test water; fittings should be sealed during installation. Kohree includes Teflon tape to help create watertight threads, and the pump’s diaphragm layout simplifies hose and clamp connections for common RV and marine plumbing setups.

• Includes Teflon tape for sealing threaded interfaces
• Residual factory test water expected—dry and reconnect on install
• Standard inlet/outlet fittings for hose or rigid plumbing connections
• Compact footprint for under-sink or compartment mounting

Where else can this pump be used besides RVs and boats?

While designed for recreational freshwater systems, the Kohree 12V pump is suitable for light-duty garden irrigation, water transfer and other low-pressure pumping tasks where 12V power is available. It’s a versatile option for off-grid or mobile applications.

• Garden watering and small irrigation circuits
• Water transfer between tanks or containers
• Backup freshwater supply for tiny homes or cabins
• Compatible with common 12V battery systems

Who is this for: The Kohree 12V RV Water Pump is built for RV and boat owners who want dependable on-demand water pressure without complex plumbing upgrades, DIYers installing fresh-water systems in caravans or tiny homes, and anyone needing a compact 12V pump for light outdoor water transfer or irrigation. It’s especially useful when you need a self-priming unit with safety features that protect the motor during occasional low-water situations.
