vertical Moor showing high DE shaft vibration

bsjhalaMember

We have Vertical cooling water pump.For Monitoring vibrations,Motor NDE end have casing vibration and shaft vibration while Motor DE have shaft vibration .In Control room DE shaft vibrations are coming of order 390 microns And casing vibrations are of NDE of motor are of order 100 microns.

And from external vibration instrument casing vibrations of Motor NDE are of 98 microns which is matching with Control room but DE casing vibrations are of order 130 microns.but shaft vibrations are order of 390 microns
Pump is running normal no physical vibrations are observed

How to compare shaft and casing vibrations

Is it safe to run the pump.

Can there be problem in instrumentation
or what could be the reason????
