The flexible lubrication system allows grease lubrication as well as
oil lubrication according to the customer‘s requirements.Mounting

Torque [kNm]
Øa2
Sumitomo centrifuge reducers provide the differential speed between the bowl and the conveyor and the torque for the conveyor. The
perfectly balanced housing is connected with the bowl and turns at
the bowl speed. The output shaft of the centrifuge reducer is connected to the conveyor and transmits the torque which is needed for
the solids transport. The input shaft can be locked by a torque arm or
driven by a back-drive motor to provide the necessary relative speed.

applications when the conveyor turns faster than the bowl.
Features & Benefits

ZSPN and ZSPV are double stage centrifuge reducers with a Cyclo
Drive stage and a planetary stage for higher ratios. ZSPN provides the
conveyor slower than the bowl; ZSPV provides the conveyor faster
than the bowl.

ZSPR is a very special double stage centrifuge reducer with a Cyclo
Drive stage and a differential planetary stage. This version allows
variable relative speed over the full control range of the motor with
slower as well as faster conveyor.
