Stenner UCFC5AD Main Shaft

The Stenner UCFC5AD main shaft is a stainless steel replacement component for compatible Stenner metering pumps. It is intended for maintenance technicians and facility managers who service chemical feed systems in water treatment or industrial applications. The part restores the drive connection between the motor and the pump head. It is sold new and ready for installation.

Replaces worn or damaged shafts

This shaft replaces an original equipment shaft that has worn, corroded or fractured after extended duty in aggressive chemical environments. The upgrade is worth it when the pump head loses prime, delivers erratic feed rates or shows visible shaft scoring during inspection. It fits models including 45MJL5A1STG1, 85MJH1A1STG1, 85MJH2A1STG1, 85MJH7A1STG1, 85MJL5A1STG1, DM5040D, FC5040D and FSK100. It also crosses to Grainger part numbers 21XZ52, 21XZ54 and the 4NA11 through 4NA16 series.

Limited to listed Stenner models

The shaft is dimensioned solely for the Stenner pump models identified in the compatibility list. It will not fit pumps from other manufacturers or Stenner series not shown above. Buyers who need a shaft for a different pump model or a complete pump assembly must source the correct part number for that equipment. No other accessories or seals are included with this shaft.

Questions about this item

Which Stenner pump models accept the UCFC5AD main shaft?

Compatible models include 45MJL5A1STG1, 85MJH1A1STG1, 85MJH2A1STG1, 85MJH7A1STG1, 85MJL5A1STG1, DM5040D, FC5040D and FSK100.

How do I install the stainless steel main shaft into the pump housing?

Remove the pump head, slide the shaft through the bearing and seal assembly, then re-secure the head bolts evenly; the step most often missed is lubricating the seal before insertion.

When should the main shaft be inspected or replaced?

Inspect the shaft for scoring or wear during routine seal changes; replace it if grooves are visible or if feed rates become inconsistent.
