How to diagnose bearing failure on an Edwards GXS / iH dry vacuum pump
Rising vibration with a bearing temperature increase means bearing wear. Log baseline readings, plan a bearing change at the next outage, and do not run past the high-temperature alarm.
How to fix an exhaust restriction on an Edwards GXS / iH dry vacuum pump
Exhaust backpressure above the design limit forces the pump to work harder and reduces vacuum depth. Locate and remove the restriction in the exhaust train.
How to diagnose a motor overload fault on an Edwards GXS / iH dry vacuum pump
Motor overload on a dry pump means mechanical resistance has increased. Check for solid polymer deposits inside the pump body before attempting a restart.
