Centrifugal pump for coolant or lubricant has rear or front cover disk of pump wheel with flow exits on outflow-side wall regions between blades

摘要

The centrifugal pump has a casing with a spiral channel and a pump wheel with at least one cover disk and several blades. The front or rear cover disk (20) has flow exits (22) in its wall regions on the outflow side between the blades (21). The spiral channel (18) runs axially to this cover disk, so that the pump wheel (13) supplies the axial spiral channel through the flow exits in the cover disk.
