Product Description
KFFKFF 12V Diaphragm Pump for All Your Water Demands
With KFFKFF's smart water pump, you can efficiently meet all your water needs! Whether you're on the go in your RV/boat or working on your farm. It delivers a powerful 3.5 gallons per minute flow rate and 55 PSI pressure, ensuring plenty of water when you need it. Don't hesitate to get one!!!
Overload Protection
The motor features built-in overload protection, automatically stopping when stuck or during abnormal situations to prevent overheating and burning.
Switch with Ease
With an automatic pressure switch, our diaphragm pump shuts itself off when the faucets are closed and runs when the faucets are opened.
Low Noise & High Quality
The water pump runs quietly and stably, so you don't have to worry about disturbing noises. It is made of corrosion-resistant material for long service life.
The on demand water pump operates with a 3.5 GPM open flow, quickly boosting water pressure. No water supply problem will be a challenge for you.
The rated pressure is set to 55 PSI, and you can adjust the pressure to 40-80 PSI. Turn clockwise to increase the pressure and vice versa to decrease it.
The RV water pump comes with two 1/2" hose adapters for easy connection to the inlet and outlet. It works with a DC power supply, so there is no need to carry the battery.
