March 0157-0005-0100 Drive Magnet Assembly

March 0157-0005-0100 TE-8 Drive Magnet Assembly

Product Overview

The March 0157-0005-0100 is a replacement external drive magnet assembly for compatible March TE-8 Series magnetic drive centrifugal pumps. It is identified for the corresponding NEMA motor arrangement and uses a 1.125-inch motor shaft bore.

The drive magnet is mounted on the motor side of the magnetic coupling. As the motor rotates, the external magnet transfers torque to the internal magnetic impeller assembly through the pump containment housing.

This component is part of the magnetic drive system rather than a liquid-contact impeller or complete pump wet end.

Key Features and Benefits

• TE-8 Series Application: Manufacturer-listed for compatible Series 8 pump assemblies.
• NEMA Motor Configuration: Designed for the corresponding motor shaft arrangement.
• Ductile Iron Construction: Matches the documented drive magnet assembly material.
• Magnetic Drive Function: Transfers torque to the internal impeller without a conventional rotating shaft seal.
• Targeted Maintenance: Allows replacement of the drive magnet while retaining other suitable pump components.

Applications and Industrial Use

This component supports maintenance of compatible March TE-8 pumps used in industrial circulation, chemical transfer, cooling and process-liquid applications. Proper magnetic coupling is important for transferring motor rotation to the pump impeller.

Replacement may be appropriate after physical damage, corrosion or other deterioration of the original external magnet assembly.

Maintenance and Installation Guidance

Inspect the motor shaft, drive magnet mounting arrangement, motor bracket and adjoining pump housing components before installation. Follow manufacturer instructions for positioning and assembly.

Verify that the external magnet rotates freely without mechanical interference before the pump is returned to operation.

Compatibility and Selection Guidance

March 0157-0005-0100 is identified for compatible TE-8 NEMA motor configurations. The IEC motor arrangement uses a different drive magnet, 0157-0091-0100. Confirm the motor shaft dimensions and complete pump model before purchase.
