The Jabsco 12v Par-Max 3 freshwater pressure pump is the updated and improved version replacing the very popular Par-Max 2.9. Ideal 12v pump to supply water at pressure to one to three taps / outlets in a 12 volt environment such as in a caravan, boat or for a small solar house application. Delivering 11 L/min @ 40PSI for a smooth flow and hassle free pump operation. One of the most popular caravan style freshwater pumps on the market.

The three chamber positive displacement diaphragm, permanent magnet motor with double ball bearing armature is the latest in quality design in 12v water pumps.

This Jabsco pressure pump automatically turns on and off when you turn the tap on and off. Runs up to 3 outlets (sink, shower, toilet) with 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 of the Jabsco Par-Max 3. A reliable 12v marine grade pressure pump with 3 year manufacturers warranty.
