Abstract
A washer for washing and dewatering cellulose pulp is disclosed including a rotatable drum with a plurality of axial compartment walls defining a plurality of outer compartments, a stationary cylindrical casing enclosing the drum, and at least one axially disposed seal dividing the annular space between the stationary casing and the drum into a number of zones for treating the pulp. The function of the seals is optimized by units for seal adjustment which include a load cell for registering a pulse signal indicating the force acting on the seals, an extractor for deriving a pulse height parameter from the registered pulse signal and a motor for moving the seal radially with respect to the drum based on the pulse height parameter.
