March 0155-0159-0200 TE-7R-MD Polypropylene Impeller 0155-0159-0200

March 0155-0159-0200 TE-7R-MD Impeller

The March 0155-0159-0200 is an OEM encapsulated impeller with carbon bushing for compatible TE-7R-MD magnetic drive centrifugal pumps. This impeller uses a black polypropylene/talc material configuration and is approximately 3.750 inches in diameter.

The impeller is a critical rotating wet-end component that transfers energy to the pumped liquid through the sealless magnetic drive arrangement.

Key Features

• Genuine March OEM replacement impeller
• Manufacturer part number 0155-0159-0200
• Encapsulated magnetic-drive design
• Black polypropylene/talc construction
• Integrated carbon bushing
• Approximately 3.750-inch impeller diameter
• Designed for compatible TE-7R-MD pumps
• Supports wet-end repair and impeller replacement

Magnetic Drive Function

The impeller rotates through magnetic coupling with the external drive magnet. This eliminates the need for a conventional rotating shaft seal between the motor and the fluid chamber.

Polypropylene and Carbon Bushing

The polypropylene/talc impeller construction is distinct from the glass-filled Kynar version used in TE-7K-MD configurations. The carbon bushing provides the specified bearing interface around the stationary shaft.

TE-7R-MD Compatibility

Parts references identify 0155-0159-0200 for compatible TE-7R-MD pumps. Other TE-7R-MD impellers use ceramic, mica-Teflon or Ryton bushings and have different part numbers.

Maintenance and Replacement

Inspect the impeller for worn bushings, cracked vanes, damaged encapsulation or abnormal rubbing. Check the shaft and thrust washers during the same maintenance procedure.

Selection Guidance

Confirm the original impeller material, bushing type and complete SKU. 0155-0159-0200 should not be confused with the Kynar impeller 0155-0160-0200.
