March 0125-0057-0100 Housing 0125-0057-0100

The March 0125-0057-0100 Rear Housing & Plug Assembly is an OEM replacement wet-end component specifically used with the March LC-2CP-MD liquid-cooled magnetic drive pump. Manufactured from polypropylene, this assembly forms the rear section of the pump wet end and incorporates the 1/4-inch MPT discharge outlet.

For LC-2CP-MD owners rebuilding a damaged or worn wet end, selecting the correct rear housing is important because March Series 2 pumps share several components but do not necessarily use the same rear-housing configuration. March identifies 0125-0057-0100 specifically in the LC-2CP-MD parts breakdown, making the manufacturer part number an important compatibility reference.

OEM LC-2CP-MD Wet End Component

The rear housing works with the polypropylene inlet cover, Viton O-ring, ceramic thrust washer, shaft, impeller and other wet-end components to create the fluid-handling section of the LC-2CP-MD. The housing supports proper internal component positioning while providing the pump discharge path.

Polypropylene Construction

Polypropylene is used extensively throughout the standard LC-2CP-MD wet end. Matching the replacement housing to the original material configuration helps preserve the intended construction of the pump. Actual chemical compatibility should always be evaluated against the process liquid, concentration, temperature and operating conditions.

When to Replace the Rear Housing

Replacement may be appropriate when the original housing has developed cracks, physical damage, connection damage, excessive wear or other conditions that prevent reliable reuse during pump maintenance. Related components such as the O-ring, impeller, shaft and thrust washer should also be inspected whenever the wet end is disassembled.

Compatibility and Selection Guidance

0125-0057-0100 is associated with the LC-2CP-MD and should not be selected only because another March pump belongs to Series 2. For example, the 2CP-MD and AC-2CP-MD use a different standard rear-housing part number. Confirm the pump nameplate, existing housing configuration, outlet connection and manufacturer part number before ordering.

For customers maintaining an LC-2CP-MD installation, the March 0125-0057-0100 provides an OEM replacement solution for restoring the compatible polypropylene rear housing and plug portion of the pump wet end without replacing an otherwise serviceable complete pump.
