March 0130-0018-1000 Series 3 Polypropylene Rear Housing 0130-0018-1000

March 0130-0018-1000 Polypropylene Rear Housing for BC-3CP-MD

The March 0130-0018-1000 is an original equipment manufacturer polypropylene rear housing used in compatible March BC-3CP-MD magnetic drive centrifugal pumps. It includes a 1/2-inch MPT discharge outlet and forms the rear section of the fluid-handling pump chamber.

This replacement housing is intended for maintenance and repair of the original wet-end assembly. Correct housing selection is important because the discharge connection, internal geometry and material must match the existing pump configuration.

Function Within the Pump Wet End

The rear housing works with the front cover to contain the liquid around the rotating impeller. It also provides the discharge connection through which liquid exits the centrifugal pump.

Proper fit between the housing, shaft, thrust components and impeller is important for maintaining the intended internal clearances.

Polypropylene Material

The polypropylene construction matches the manufacturer-listed housing material for this part. Chemical compatibility depends on the complete pump wet-end configuration and the conditions of the application.

Threaded Discharge Connection

This rear housing uses a 1/2-inch MPT outlet. It should not be confused with smooth-outlet or differently threaded rear housings, even when the components appear similar.

Compatible March Pump Applications

March identifies 0130-0018-1000 in the BC-3CP-MD parts breakdown. Compatibility with other Series 3 models should be established using the applicable manufacturer parts list rather than assuming all Series 3 housings are interchangeable.

Maintenance and Replacement

Inspect the existing rear housing for cracks, damaged threads, distortion, chemical deterioration or internal wear. Check the shaft, impeller, thrust washer and O-ring during wet-end service.

Ordering Guidance

Verify the complete pump model, polypropylene material and 1/2-inch MPT discharge connection before ordering. March 0130-0018-1000 is an individual rear housing, not a complete pump assembly.
