MARCH PUMPS LC-3CP-MD Mag-Drive Centrifugal Pump 115V

The March LC-3CP-MD Mag-Drive Centrifugal Pump 115V is a centrifugal magnetic drive pump, eliminating the need for a shaft seal. Pumps are serviceable with a screwdriver. The “LC” is hermetically encapsulated and liquid cooled which allows the pump to be run fully submerged or in open air for complete moisture protection. Direct Replacement for Dometic PML500 115V, Part Number: 225500005


Pumps are not self-priming, lack a suction lift, and thus require a flooded suction. Pumps cannot be run dry because the impeller requires the liquid being pumped for lubrication. For liquids with a specific gravity greater than water, have a higher viscosity, or for elevated temperatures, a trimmed impeller may be necessary. For
application assistance, contact March Pump.


Motors are available in different electrical configurations such as 115 Volt 50/60 Hz, or 230 Volt 50/60 Hz, 1 phase. The motors are U.L. listed and rated as continuous duty. Models have a 6 foot (1.8 m) cord.
