Lubrication
Pump bearings and gear should run in an oil bath. Replacement of these bearings and gear wheels
is recommended after 20,000 hours of operation.
However, the shorter change intervals required for particularly difficult operating conditions, such
as:
- High temperature variations
- High pressure fluctuations
Oil in Gearbox is recommended to be changed once a year or every 3,000 operating hours.
However, the interval of changing oil should be adjusted according to the operating conditions.
Check the oil level in the Gearbox weekly and top up the gear oil if necessary.
