This 12V electric diaphragm pump moves water efficiently with flow options from 1.8 to 5.0 gallons per minute. Whether you're running a sink, shower, or cleaning setup, you get stable pressure without constant adjustments. The built-in pressure switch activates the pump automatically when water flows and shuts it off when it stops.

You can fine-tune the pressure between 40 and 100 PSI using a simple screw adjustment. Turn clockwise to increase pressure or reduce it as needed, giving you full control over how water flows in your system.

The motor runs smoothly with reduced noise thanks to its anti-vibration base and internal design. This makes it suitable for enclosed spaces like RVs and cabins where loud pumps quickly become a problem.
