About These Products Power to Fit Your Needs: These 12V diaphragm pumps are available in three versions depending on the desired flow rate and pressure. The 1.8 GPM model delivers 6.81 L/min at 60 PSI, ideal for basic needs. The 3.5 GPM model offers 13.25 L/min at 50 PSI, a mid-range solution for multiple water outlets. The 5.0 GPM model, with 18.93 L/min at 70 PSI, is perfect for higher-demand applications such as watering or cleaning. Smart Automatic Pressure Switch: All versions feature an adjustable pressure switch from 40 to 100 PSI that activates the pump when the tap is opened and automatically shuts it off when it is closed. Tested over 200,000 times, these pumps ensure long-term reliability. Quiet Operation with Copper Motor: They feature a pure copper motor and a sound-dampening base to minimize noise during operation. Perfect for indoor use, vehicles, or situations where quiet operation is essential.

Additionally, the internal check valve ensures continuous flow even if the pump or valve fails. Easy Installation and Universal Compatibility: Thanks to their standard 1/2" (20.955 mm) MNPT inlet and outlet, these pumps are easy to install as a replacement or upgrade. They are compatible with RVs, boats, food trucks, irrigation systems, and more.
