The Jabsco 24v Par-Max HD6, J20-285 freshwater pressure pump is a robust, high performing 12v pump supplying water at pressure to up to six taps / outlets in a 24 volt environment such as in a caravan, boat or for a small solar house application delivering 22.7 L/min at open flow and @ 60PSI at pressure for a smooth flow and hassle free pump operation. 

The heavy duty (HD models) include a heavy duty wider diameter motor with a powder-coated shell, cast aluminium end bells and lowering housing to improve pressure capability and offer longer life and exceptional performance.

This Jabsco pressure pump automatically turns on and off when you turn the tap on and off. Runs up to 6 outlets (sink, shower, toilet, washing machine, tap). The rule of thumb for sizing your pump is 1 GPM (gallon per minute) per outlet is required.

Providing a very smooth water flow even at low demand due to its integrated by-pass valve which controls unwanted cycling and noise.  This accounts for the popularity and reliability of the Jabsco Par-Max freshwater pump range. A reliable 24v marine grade pressure pump backed by 3 year warranty.
