AMETEK Spectro Scientific
Compressor oil analysis after mechanical seals. Pump maintenance using oil analysis focuses mostly on the bearings and bearing life. Most pump bearings do not reach their theoretical (L10) fatigue life. Two-thirds of all rolling element bearings in service, which had to be replaced, failed prematurely. Only one-third of bearings fail due to fatigue spalling (L10 Life). Of the two-thirds that failed prematurely the break down is as follows: 30% of bearings fail early due to lubrication problems. Poor or incorrect lubricant... (read more)Browse Oil Sensors and Analyzers Datasheets for AMETEK Spectro Scientific -
