Jabsco Mag Drive Centrifugal Pump, 14 GPM, 110V AC, 1/2 in NPT

Overview

The Jabsco 436979 is a magnetically coupled centrifugal pump for 110V AC 60Hz systems that moves up to 13.2 GPM through 1/2 inch NPT ports and reaches a closed-valve head of 19 feet.

It is built for continuous-duty circulation jobs on board, including marine air conditioner circulation, ice maker circuits, hot water circulation, livewell systems, and bait tank installations. The magnetic coupling helps limit heat transfer into the pumped fluid, which matters in circulation systems that run for long periods.

For fit planning, the pump body measures 8.4 inches long, 4.0 inches wide, and 5.62 inches high. Current draw is 0.95 amps with a 60W motor and a 1.0 amp fuse, so this is an AC pump for shore power or generator-fed circuits, not a 12V or 24V DC setup.

Key features

• 110V AC 60Hz pump for onboard AC systems
• Run-out flow rate of 13.2 GPM with a closed-valve head of 19 feet
• Magnetically coupled pump layout for leak-free continuous-duty circulation
• 1/2 inch NPT ports for common marine circulation plumbing
• IPX5 motor housing for spaces that may see spray or washdown
• Non-metallic pump head in chemical-resistant thermoplastics
• Polypropylene housing and encapsulated magnet, PPS spindle housing, alumina ceramic spindle, and EPDM O-ring
• Published dimensions of 8.4 x 4.0 x 5.62 inches for installation checks

Compatibility and fit

This pump fits boats that already have 110V AC available and need a circulation pump rather than a general transfer or utility pump. The main checkpoints before ordering are system voltage, 1/2 inch NPT plumbing, and enough room to mount a body that is just over 8 inches long.

The published performance figures are based on clean cold water. In real marine systems, flow will depend on hose runs, lift, fittings, and how clean the water path stays.

Installation and setup

The compact housing helps in machinery spaces, service lockers, and HVAC compartments where space is limited but access still matters. Leave room around the ports and wiring so the pump can be mounted cleanly and serviced later without reworking the plumbing.

The IPX5 motor housing is a useful detail for marine installations, but this is still a 110V AC component and should be wired on the correct protected circuit with the specified 1.0 amp fuse. Matching the pump to the right AC supply is just as important as matching the plumbing.

Use on board

This pump suits cruisers and larger powerboats running marine air conditioning, hot water loops, or ice maker circulation from shore power or a generator. It also fits bait or livewell circulation jobs where the system is set up around AC power and continuous flow.

It is a good match for buyers who need clear installation numbers before they commit, especially when voltage, port size, and mounting space have to line up with an existing onboard system.
