What should we do to make my rotary vane pumps last longer

1. work condition must be dry, so we could not put the rotary vane pump in a wet or dirty place, and make sure there’s enough space while install the pump.

2. Keep the pump cool, all of the rotary vacuum pumps are air cooling, so we must check the air fan and make sure it works well.

3. Choose the high quality spare parts, including the oil filter, inlet air filters and oil mist separators, the poor quality spare parts could not last long time and may damage the pump easily.

4. Use the gas ballast
