The Jabsco Par Max 3.5 24v marine grade water pump is a powerful 3 chamber automatic pressure pump capable of serving 3 x 12mm outlets simultaneously with its 3.5 GPM 13.2 litres per minute capacity and 40 PSI pressure.

The 12v and 24v Jabsco water pump range give very smooth water flow even at low demand due to their built-in pulsation dampening by-pass valve which controls unwanted cycling and reduces noise. 

Ideal water pump for pumping water to tap, shower, toilet and kitchen outlets in a 24 volt environment such as a boat, solar house or caravan. 

  • Automatically turns on and off when you turn the tap on and off. 
  • Reliable marine grade pump.
  • Supplied with 2 x 1/2" male thread and 2 x 12mm barbed straight snap-in ports.
  • Pressure switch: cut in 20 PSI - cut out 40 PSI
