Product description
Pre-chamber
The large pre-chamber is filled with gear oil and absorbs fluid ingress through the seal on
the fluid side. A mechanical seal is used as the seal on the fluid side. A rotary shaft seal seals
towards the gear chamber.
Gear chamber
The gear chamber is filled with gear oil and ensures continuous lubrication of the planetary
gear and the gear bearings. A mechanical seal seals towards the sealing chamber.
Sealing chamber
The large sealing chamber is filled with white oil and absorbs any leakage from the gear
chamber. A rotary shaft seal seals towards the motor.
