The UnitedBuilt M02153MS impeller is the clockwise (CW) cast iron replacement for the M3Z pump configurations below. Its precision-machined construction and rotation-specific part number make it important to match the installed pump, not simply the M3Z family name.
This impeller is used in both rope-seal and mechanical-seal versions with clockwise rotation. The opposite-rotation impeller has a different part number, M02181MS. Confirm the pump identity and rotation before selecting the replacement; changing an impeller alone is not a direction-conversion procedure.
