Maintenance Schedule

The maintenance intervals depend very much on the individual operating conditions. The intervals given below are considered as starting values which should be shortened or extended as appropriate. Particularly harsh applications or heavy duty operation, such as high dust loads in the environment or in the process gas, other contamination or ingress of process material, can make it necessary to shorten the maintenance intervals significantly.

Interval

Maintenance work

Monthly

  1. Check the inlet screen, clean if necessary.

In case of an inlet filter (IF) being installed:

  1. Check the inlet filter cartridge, replace if necessary.

Every 3 months
  1. Check the oil level, see Oil Level Inspection.

Every 6 months

  1. Clean the machine from dust and dirt.

In case of a coupling (CPL) being installed:

  1. Check the coupling (CPL) for backlash and wear.

Gas tight version and light chemical version only
Every 5000 hours or after 2 years

Depending on the requirements in terms of gas tightness:

  1. Replace sealing rings (contact Busch).

Gas tight version only
Every 10000 hours or after 2 years

  1. Check that pressure relief lines (PRL) are not clogged, see Pressure Relief Lines Maintenance.

Light chemical version only
Every 10000 hours or after 2 years

  1. Check that the lines of the barrier gas system (BGS) are not clogged, see Barrier Gas System Maintenance.

Every 20000 hours
  1. Change the oil.

The change interval of 20000 operating hours is valid for Busch approved oils only. The change interval depends very much on the operating conditions. Borderline operation may reduce the change interval down to approximately 5000 operating hours. Other oils may reduce the change interval.

Every 40000 hours or after 6 years

  1. Have a major overhaul on the machine (contact Busch).
