Description
Restore seawater-loop flow in compatible marine air-conditioning systems with the March Pump Wet End Repair Kit 0150-0144-0100 for LC-3M-MD and PML500 pumps. This submersible wet-end overhaul and rebuild kit is designed for liquid-cooled March LC-3M-MD and PML500 pumps used in marine A/C seawater-loop maintenance for 5,000 to 12,000 BTU systems.
The kit includes a precision impeller, front pump housing, Viton O-ring, ceramic shaft, and thrust washer. It uses glass-filled polypropylene, high-purity ceramic, and marine Viton components. The reference pump flow is 510 GPH (8.5 GPM / 19.3 LPM), and the kit is specified for continuous submerged-liquid duty up to 130 degrees F (54 degrees C).

Compatibility and Installation
This kit is intended only for compatible March LC-3M-MD and PML500 submersible liquid-cooled A/C pumps. Confirm the exact installed model, pump revision, wet-end layout, voltage version, and required service parts before purchase. The 510 GPH figure is a reference pump-flow rating, not a performance is designed to support for a rebuilt or installed system.
Disconnect electrical power and isolate seawater plumbing before service. Follow March Pumps documentation for wet-end removal, shaft and thrust-washer positioning, O-ring seating, housing reassembly, and leak testing. Inspect the seawater intake, seacock, strainer, hose routing, and discharge plumbing for restrictions. Do not exceed the 130 degrees F maximum continuous submerged-liquid-duty temperature.
Before Ordering
