The March LC-3CP-MD is a magnetic drive pump that can run either submerged or in open air, delivering up to 9 GPM at heads to 19 feet (8 PSI) on a 115V hermetically sealed motor rated to 130°F. Its discharge port routes a small amount of pumped liquid through copper tubing to cool the motor when the pump runs in open air, a design detail that supports continuous duty in both configurations. It's a well-documented replacement pump for marine air conditioning and heating systems from Taylor Made, Cruisair, Dometic, Aqua Air, and Kool Air, as well as SeaRay factory-installed units — beyond marine use, it's also common in film processors, ice makers, laboratory and medical equipment, and vapor degreasers. Because the impeller is magnetically coupled with no mechanical shaft seal, it runs leak-free with minimal maintenance.

Applications for the AC-3CP-MD Magnetic Drive Pump include ice makers, laboratory and medical equipment, vapor degreasers, and marine air conditioning systems.
