March 1C-MD Magnetic Drive Pump 230V

March 1C-MD Magnetic Drive Pump 230V

March builds the 1C-MD as a magnetically coupled centrifugal pump with polypropylene wet end with a ceramic magnet impeller. Nothing penetrates the liquid end, so the failure mode that dominates conventional pumps, a worn shaft seal weeping onto the motor, does not exist here. It is a straightforward pump to live with and a straightforward one to rebuild.

The 1C-MD needs a flooded suction and a liquid that keeps flowing through it. It will not lift and it will not tolerate dry running, and a trimmed impeller is the correct answer when the liquid has a higher specific gravity or viscosity than water, or when the temperature is elevated. Beyond that it is a low maintenance pump with three wear parts and no seal to service.

Frequently Asked Questions

Q: What happens if it runs dry?
The impeller bushing and shaft lose their only lubricant and wear very quickly. A few seconds is survivable, a few minutes usually is not.

Q: Which way should the motor turn?
Clockwise when you are looking into the inlet of the pump.

Q: Why would I need a trimmed impeller?
Liquids heavier or thicker than water, and hot liquids, all load the magnetic coupling harder. Trimming the impeller brings the load back within the coupling rating.

Q: What wears out on this pump?
The impeller assembly, the stationary shaft and the thrust washers. Everything else in the wet end is static.
