The Jabsco 31620-0094 Par Max 4 pressure-controlled pump delivers on-demand freshwater flow for marine and recreational systems using 24V DC power. It provides an open flow output of 16 liters per minute (3.5 gallons per minute) with a pressure switch that cuts in at 1.4 bar (20 psi) and cuts out at 2.8 bar (40 psi) to maintain consistent pressure at multiple outlets. A self-priming, multi-diaphragm design supports up to 1.5 m (4.9 ft) vertical lift, can run dry without damage, and includes an integrated bypass for smooth flow that removes the need for an accumulator tank, plus thermal overload protection for reliable operation in harsh environments.
