The workingprinciple of pulper is to generate strongturbulence in the water which is achieved bymeans of agitator blades available in varietyof designs. Due to the agitation and circulationof the water in the pulper, the waste paper isexposed to strong abrasion. distinction ismade between intermittent operation, operationin batch quantities, and continuous operation.The main element of an intermittent or discon-tinuous pulper is spiral or screw-shaped rotor, whereas in continuous pulper it is perforated plate with upstream agitator blades.In both cases the waste paper is dissolved by means of impact and tumbling processes. Pulpers may be either vertical or horizontal indesign. Vertical pulpers Vertical, extra strong output shaft bearingarrangements (with additional thrust bearing)on the bevel-helical gear units of the .PV typeabsorb great external axial and radial forcesoriginating from the pulper. Input and outputshafts of the gear unit are provided with so-called Taconite seals (seal combination of radialshaft seal, diaphragm gland, and refillablelabyrinth). On the output shaft, sling diskprevents water from penetrating into the gear unit. The gear units are provided with force- feed lubrication system and they are cooled byan oil supply system type OWGE, variant 2.There are also pulper designs with rotors having separate bearings so that no external forces orig- inating from the gear unit have to be absorbed. In this case, the gear unit output shaft and thepulper input shaft can be connected, for in
