March 0130-0025-1000 Buna-N Bracket O-Ring

The March 0130-0025-1000 is a genuine OEM Buna-N bracket O-ring designed for compatible March Series 3CP magnetic drive centrifugal pumps, including the LC-3CP-MD. It provides the specified sealing interface within the pump bracket assembly.

Bracket O-Ring Function

The bracket O-ring forms an elastomeric sealing interface at its designated location in the pump assembly. Proper sealing helps maintain the intended fluid containment arrangement and supports reliable service of the magnetic drive pump.

Buna-N Elastomer Construction

Buna-N is the manufacturer-listed material for this part. Its suitability depends on the pumped liquid, operating temperature and other service conditions. Alternative elastomers should not be substituted without confirming application requirements.

Compatible Pump Models

March and distributor parts references associate 0130-0025-1000 with compatible 3CP-MD and LC-3CP-MD configurations. The LC-3CP-MD parts breakdown identifies it as the bracket O-ring rather than the main housing cover seal.

Maintenance and Replacement

Inspect the O-ring during scheduled maintenance or pump disassembly. Replace it if it shows compression set, cracks, cuts, swelling or other damage. Ensure that the sealing groove is clean and the new O-ring is seated correctly.

Compatibility and Selection Guidance

Different Series 3 pumps may use O-rings with different sizes or materials. Confirm the original bracket sealing arrangement and exact SKU before ordering. March 0130-0025-1000 is a single replacement O-ring rather than a complete seal kit.
