Reply to "High temperature at pump NDE bearing"

Thanks Mr. Kishore.

Shaft alignment is within tolerance. Do you mean bearing misalignment I need to check?

This is a sump lubrication type 7309 ball bearing (2* Back to Back).

Rub where we can expect? Is it between oil seal and shaft?

Pump DE bearing temperature is normal whereas NDE is 15 degrees higher(this very abnormal compared with other identical pumps)

Pump shaft, wear ings and bearings are recently replaced!
