March 0155-0160-0200 TE-7K-MD Kynar Impeller

The March 0155-0160-0200 is an OEM encapsulated impeller with carbon bushing for compatible TE-7K-MD magnetic drive pumps. Its glass-filled Kynar construction is intended for the specified chemical-service wet-end configuration.

The impeller receives rotational torque through magnetic coupling and transfers energy to the process liquid without requiring a conventional rotating mechanical shaft seal.

Key Features

• Genuine March OEM replacement impeller
• Manufacturer part number 0155-0160-0200
• Glass-filled Kynar construction
• Encapsulated magnetic-drive design
• Integrated carbon bushing
• Approximately 3.750-inch impeller diameter
• Designed for compatible TE-7K-MD pumps
• Also listed in selected self-priming TE-7K assemblies

Sealless Magnetic Drive Function

The impeller rotates inside the pump wet end while receiving torque from an external drive magnet. This arrangement keeps the motor-side shaft separated from the process liquid.

Glass-Filled Kynar and Carbon Bushing

The glass-filled Kynar impeller is a different material configuration from the polypropylene TE-7R-MD impeller. Its carbon bushing provides the intended bearing interface with the stationary shaft.

TE-7K-MD Compatibility

March lists 0155-0160-0200 in compatible TE-7K-MD configurations, including certain flanged and self-priming assemblies. Alternative impellers with other bushing materials have different part numbers.

Maintenance and Replacement

Inspect the impeller for bushing wear, cracking, damaged vanes and abnormal rubbing. Check the shaft, thrust washer and rear housing for related wear before installing a replacement.

Selection Guidance

Confirm the complete pump model, impeller material and carbon-bushing requirement. 0155-0160-0200 identifies the specific Kynar impeller configuration and is not interchangeable by default with polypropylene variants.
