STANDARD SIZE, EASY REPLACEMENT Our 12V diaphragm pump is equipped with a standard 1/2" MNPT inlet and outlet, replacing your existing pump is a breeze. It is ideal for use in RVs, boats, campers, food trucks and more, bringing convenience to your lifestyle.
SAY GOODBYE TO LOW WATER PRESSURE Upgrade to our 3-chamber 12V water pump that delivers a high flow rate of 3.0GPM (11.36L/min) at constant 50PSI. It is designed to efficiently and reliably cover all your daily water needs, saving you valuable time.
SAFETY YOU CAN TRUST This 12V water pump has overheating and overload protection to extend its service life. It also supports dry running and features an integrated check valve bypass switch to ensure uninterrupted water supply even if the pump or check valve fails.
EXTREMELY QUIET OPERATION Our 12V diaphragm pump adopts pure copper motor for smooth and quiet operation. The plastic pump body and noise-reducing base effectively minimize sound, so that neither your work nor sleep are disturbed.
AUTOMATIC PRESSURE SWITCH Adjust your water pressure with an adjustable range of 40 to 100 PSI. The pressure switch if necessary, automatically starts the pump when you open the tap, and stops it when you close it. Tested over 200,000 times for durability, built to last.
