For oil lubricated liquid ring vacuum pumps and compressors:
- Drain the oil and look for signs of moisture. If moisture is present, remove the oil and inspect for corrosion on any parts. Any sight of corrosion should be thoroughly cleaned, the bearing should be replaced. Install new oil.
- Flush out piping, strainers and heat exchangers. Making sure to block in vacuum pumps and or compressors so as not to allow debris to be forced into the pump/ compressor during flushing.
- Flush out vacuum pump or compressor independently.
- Hand rotate vacuum pump or compressor to determine if locked up prior to start up.
For grease lubricated liquid ring vacuum pumps and compressors:
- Remove the grease caps. Look for moisture or signs of corrosion. Any sight of corrosion, the bearing should be replaced. Purge the bearing with new grease.
- Flush out piping, strainers and heat exchangers. Making sure to block in vacuum pumps and or compressors so not allowing debris to be forced into the pump/ compressor during flushing.
- Flush out Vacuum Pump and or compressor independently.
