March 0145-0027-0100 Drive Magnet for Series 4 Pumps

March 0145-0027-0100 Replacement Drive Magnet

Product Overview

The March 0145-0027-0100 is a replacement drive magnet used with compatible March Series 4 magnetic drive centrifugal pumps. Mounted on the motor side, the drive magnet transfers rotational torque through magnetic coupling to the impeller magnet inside the pump wet end.

March identifies this component in BC-4 pump parts breakdowns. Correct magnet selection and positioning are important for maintaining the original drive coupling arrangement.

Key Features and Benefits

• Motor-Side Drive Component: Transfers torque to the internal magnetic impeller.
• Series 4 Application: Identified for compatible BC-4 pump configurations.
• Individual Replacement: Supports targeted motor-side service.
• Original Drive Arrangement: Maintains the manufacturer-designated magnetic coupling when correctly installed.

Applications and Maintenance

This magnet supports compatible circulation and liquid-transfer equipment. Replacement may be required if the original magnet is physically damaged, improperly secured or unsuitable for reuse.

Inspect the motor shaft, bracket, fasteners and impeller magnet during service. Follow the March Pump installation instructions for drive magnet positioning and safe handling.

Compatibility and Selection Guidance

Verify the complete BC-4 Series pump model and original drive magnet part number. Drive magnets from other pump families may have different mounting dimensions and must not be substituted without confirmation.
