The Jabsco 36900-1000 Marine Par belt drive high-pressure water pressure pump delivers consistent onboard water flow with a 12V DC motor rated at 4.2 GPM (15.9 liters/min) and 40 PSI (2.8 bar), supporting systems with up to 5 outlets. Its self-priming diaphragm design can run dry without damage, while the belt drive helps provide smooth, quiet operation. Corrosion-resistant construction and built-in control via a pressure switch (on at 20 PSI, off at 40 PSI) make it well-suited for marine freshwater supply, showers, galleys, and washdown use on boats, yachts, and recreational vehicles.
