Jabsco 1" Electro-Magnetic Clutch Pump - 12V

The Jabsco 1" Electro-Magnetic Clutch Pump is a marine-duty circulation and transfer system designed for serious boaters who demand reliability in saltwater and freshwater environments. Whether you're managing engine cooling, live well aeration, or washdown systems aboard your vessel, this 12-volt pump delivers consistent performance when you need it most. Built to handle the harsh realities of life on the water, the electromagnetic clutch engagement allows remote operation without constant manual intervention, making it an essential upgrade for commercial fishing boats, cruising sailboats, and high-performance center consoles.

This pump features a nominal flow rate of 23 US gallons per minute at 1750 RPM, with self-priming capability from completely dry up to 7.8 feet—a critical advantage when managing bilge water or transitioning between tanks. The construction combines marine-grade bronze and stainless steel throughout, resisting corrosion from saltwater exposure and galvanic degradation that compromises inferior pumps within a single season. The electromagnetic clutch mechanism eliminates parasitic belt drag when the pump is idle, reducing electrical load on your charging system and extending engine hours between services. One-inch intake and discharge ports accommodate standard marine hose fittings, and the compact 9 x 8 x 14-inch footprint fits tight engine compartments without requiring major installation modifications.

Experienced boaters choose this Jabsco pump for engine cooling loops, emergency dewatering, and live well circulation on everything from 25-foot offshore boats to larger commercial vessels. The self-priming design proves invaluable during bilge pump emergencies or when repositioning fuel between tanks in rough conditions. Service intervals remain predictable thanks to accessible internal components and a sealed design that keeps corrosive saltwater away from critical seals. Twelve-volt operation integrates seamlessly with standard marine electrical systems, and the electromagnetic clutch accepts both momentary switches and relay control for automated operation tied to engine parameters or float switches.
