No verified differences are recorded for these comparison fields. Confirm the full nameplate and suffixes before choosing a replacement.
Check displacement, flange, shaft diameter and key or spline. Compare the actual coupling and mounting dimensions before choosing a replacement.
Match main-port threads, drain arrangement and distributor. Check the duty against both the applicable performance curve and the shaft torque limit; a series torque figure may exceed the selected shaft limit.
Manufacturer catalog and model-code reference. Confirm the supplied unit against its nameplate and the applicable manual.
