Abstract: An apparatus includes a pump unit with a pump which is driven by a wet-rotor motor. The wet-rotor motor is surrounded by a motor housing. The motor housing has a bushing arrangement for supplying power to the wet-rotor motor, and the bushing arrangement has, on a part of the motor housing, openings into which one cable bushing is arranged fixedly with the aid of a holding element. Each cable bushing has a conducting body and an insulating body. The insulating body has at least partially conical surfaces which interact with the conducting body.

Abstract: An apparatus includes a pump unit with a pump which is driven by a wet-rotor motor. The wet-rotor motor is surrounded by a motor housing and has a stator winding. The motor housing has a bushing arrangement for supplying power to the stator winding of the wet-rotor motor, and the bushing arrangement has, on a part of the motor housing, openings into which in each case one cable bushing is fixed with the aid of a holding element. Each cable bushing has a guide body and an insulating body. The guide body and the stator winding have a connection. The connection is formed as a press connection.

Abstract: A method for operating a data processing unit according to a program for creating individual shelf images for a multitude of points of sale (POS) of a trading firm, including accessing assortment data which define an individual assortment of different items with attributes for every POS, offering a user to interactively define blocks via input- and output devices, each block comprising items with at least one attribute specific for the block, accessing the blocks in a data memory, accessing shelf data with data of at least one shelf of every POS in a data memory, offering the user to interactively develop a sequential order of placement rules, accessing the order of placement rules in a data memory and for each POS, applying placement rules, and determining the placement positions of items in the shelf of the POS, and visualizing the placement positions of the items in a shelf image.
