The Jabsco Sensor Max II is a 12V variable-speed freshwater pump. Instead of switching on and off at full speed, it adjusts its motor speed to match how much water is being used, so the flow stays steady and quiet with no water hammer. It delivers up to 5 GPM at a maximum running pressure of 40 PSI and can supply up to five outlets. The motor is a brushed, totally enclosed, permanent magnet design.
Because it controls its own speed, it does not need an accumulator tank, which saves space under a berth or in a locker. It is much quieter at night when someone opens a faucet briefly, and it draws less power than a pump that runs at full speed every time. That helps when the boat is on batteries at anchor.
Quick-connect 1/2-inch and 3/4-inch hose barbs, straight and elbow, are included along with a 40-mesh strainer. Flush the plumbing before installing, and keep inlet pressure under 30 PSI. See the rest of our bilge and water pumps for other freshwater and washdown pumps.
