Elevate your marine or RV water system with the Jabsco Double Stack Water System, engineered for high performance and reliability. This robust 24V system delivers an impressive 9 gallons per minute (GPM) flow rate at 40 PSI, ensuring consistent, powerful water pressure for up to 7 outlets. Perfect for showers, sinks, washdowns, and more on larger vessels or vehicles.The innovative double-stack design integrates two Jabsco PAR-MAX pumps with a pre-pressurized accumulator tank, providing smooth, pulsation-free flow while preventing pump cycling for enhanced efficiency and durability. Self-priming up to 6-10 feet (2-3 meters), this system offers versatile installation options and features run-dry capability, protecting the pumps during low-water conditions. Under low demand, the primary pump operates at 4.8 GPM (18 LPM), while high-demand scenarios activate the secondary pump to achieve the full 9 GPM (34 LPM) capacity, drawing only 8 amps at 24V for maximum efficiency.FeaturesRun-dry abilitySmooth, even flowTwo stage operationThermal overload protectionInternal bladder accumulator tankComplies with ISO 8846 Marine (Ignition Protection)Three-year warrantySpecificationsFlow output: 9 GPM (34 LPM)Shut-Off pressure: 40 psi (2.8 bar)Fitting connection (hose tail): 3/4″ (19 mm)DC voltage: 24 VLength: 13.6″ (34.5 cm)Width: 12.2″ (31 cm)Height: 13.6″ (34.5 cm)Weight: 21 lb (9.58 kg)
