March 0157-0050-0500 TE-8K-MD Kynar Impeller

The March 0157-0050-0500 is an OEM encapsulated magnetic-drive impeller designed for compatible TE-8K-MD centrifugal pumps. Its glass-filled Kynar construction and carbon bushing distinguish it from other Series 8 impeller configurations.

This impeller is an important rotating component within the sealless wet end, transferring rotational energy to the process liquid through magnetic coupling.

Key Features

• Genuine March Series 8 replacement impeller
• Manufacturer part number 0157-0050-0500
• Glass-filled Kynar construction
• Encapsulated magnetic-drive design
• Integrated carbon bushing
• Approximately 5.187-inch impeller diameter
• Designed for compatible TE-8K-MD pumps
• Supports wet-end repair without replacing the complete pump

Magnetic Drive Impeller Function

The impeller receives torque magnetically from the motor-side drive magnet. This arrangement allows the wet end to operate without a conventional rotating mechanical shaft seal. The carbon bushing provides the specified bearing interface around the stationary shaft.

Glass-Filled Kynar Construction

Glass-filled Kynar is used in compatible March chemical-service pump assemblies. Its suitability depends on the specific liquid, concentration, temperature and operating environment. The material and bushing combination must match the original pump configuration.

TE-8K-MD Compatibility

March lists this part as a carbon-bushing impeller option for the TE-8K-MD. Related Series 8 impellers with Ryton or mica-Teflon bushings carry different manufacturer part numbers and should not be substituted without verification.

Maintenance and Replacement

Inspect the impeller for damaged vanes, cracks, bushing wear, magnet damage and abnormal rubbing. Check the ceramic shaft and thrust washers at the same time, since worn mating components can affect the replacement impeller.

Selection Guidance

Verify the complete pump model and original impeller material and bushing type before ordering. 0157-0050-0500 is the specific Kynar and carbon-bushing configuration for compatible TE-8K-MD applications.
