Some additonal informations
- Is this a new installation?
Yes, both the pump and motors are new
- Have you verified your instrumentation?
The sensors were calibrated just before the measurement
- pump speed =?
740rpm
- # of balls in the suspect bearing = ?
Roller bearing, 14 rollers...
I am working on a new 45kW centrifugal water pump, which is >70C at the roller bearing pedestal. I wonder what' s causing such high temperature.
The vibration measured at the bearing pedestal is indeed very small. The pump seems to be well balanced and lubricated.
