The Dometic PML500-115V heavy-duty centrifugal pump provides a steady flow of cooling water through the air conditioning system: ensuring a top cooling performance. The glass-reinforced polypropylene head pump has magnetic drive impellers, and is available with submersible or air-cooled motors. Centrifugal pumps must be mounted below the water line. Self-priming pumps are also available for above-water-line applications. A scoop type through-hull and a seawater strainer are recommended for proper operation. When more than one air conditioning unit is served by a single pump, a separate pump relay is used. To complete the installation, Dometic can also supply water manifolds, hose, and fittings. Larger pumps have bronze heads with mechanical seals, and air-cooled, drip-proof motors. Ensure your onboard comfort.
