Abstract

1. Device for a floating disposal and fixing of a centrifugal pump casing to an electric motor by means of an intermediate piece separating from the pump the medium to be pumped by the motor as well as the media present in the motor, the intermediate piece consisting of a corrosion-resistant material and being disposed on the side of the drive in centered position over a first recess at a bearing plate of the electric motor and fixed with connection means and on the side of the pump in centered position over a second recess at the pump casing and fixed with an assembly for a positive and/or non-positive connection, characterized in that the bearing plate of the electric motor facing the pump is integrally connected with the casing (1b) of the bearing off the side of the pump as well as integrally connected with a lantern casing (1d).
