Motor or attached component drain connection
Use the drain line when pressure in the return line exceeds the permissible pressure on the shaft seal of
the attached component.
Connect the drain line either at the:
•
Motor drain connection
•
Drain connection of the attached component
If a drain line is fitted to the attached component, it must be possible for oil to flow freely between motor
and attached component.
The drain line must be led to the tank in such a way that there is no risk of the motor and attached
component being drained of oil when at rest.
The maximum pressure in the drain line is limited by the attached component and its shaft seal.
