The present invention relates to a packing element for a structured packing including at least two adjacent corrugated sheets, wherein each of the corrugated sheets comprises a plurality of alternately oriented peaks and troughs, wherein adjacent corrugated sheets are oriented such that the corrugations of the adjacent corrugated sheets intersect in crisscross fashion with the corrugations of the corrugated sheets extending obliquely relative to the vertical direction, wherein each corrugated sheet contacts each of the adjacent corrugated sheets at points of intersection between the corrugations of the corrugated sheet and those of the adjacent corrugated sheets, wherein all corrugated sheets are tied together by means of at least one rod, wherein the at least one rod penetrates the corrugated sheets perpendicularly to the longitudinal section of the corrugated sheets, wherein on the at least one rod before the first corrugated sheet of the packing element and/or after the last corrugated sheet of the packing element at least one mounting clip is provided for fixing the corrugated sheets on the rod, wherein the mounting clip comprises a central part forming a coupling portion for coupling the mounting clip to the rod and two opposing lateral parts forming a clamping portion for a clamping engagement with the corrugated sheet, wherein the lateral parts are connected with the central part and angled with respect to the central part.


A device for applying a mixed component includes first and second receptacles configured to receive first and second components, respectively, a static mixing nozzle, an applicator and an operating member. The static mixing nozzle includes a plurality of mixing elements, has a first end and a second end, and is in fluid communication with the first and second receptacles. The applicator includes a spray tip and an input for pressurized fluid, the spray tip is disposed downstream of the second end of the static mixing nozzle and is in fluid communication with the static mixing nozzle. The operating member is disposed on the applicator and is configured to control the pressurized fluid.


A pump for fluids includes a pump housing, a power source enclosed within the housing, a drive shaft connected to the power source, at least one pump inlet arranged in the pump housing, a pump outlet arranged in the pump housing, a first impeller arranged within a first impeller chamber and rotated by the drive shaft, and a second impeller arranged within a second impeller chamber and rotated by the drive shaft. The pump is changeable between a first configuration in which the first and second impeller are arranged in parallel to provide a high pumping capacity, and a second configuration in which the first and second impeller are arranged in series to provide a pump with less pumping capacity.

A method is disclosed for producing an apparatus for dispensing a medium (18). The apparatus comprises a cartridge in which a piston is movably receivable. The cartridge comprises a cartridge body and a cartridge cover. The method comprises the step of providing a first part in a mold of a molding device, wherein the first part is chosen from at least one of the following parts: cartridge body; piston; cartridge cover. Subsequently, a second part different from the first part is molded in the mold of the molding device, wherein the first part constitutes a part of the mold for the second part.


The present invention relates to an applicator for a fluid ingredient, comprising- at least one storage chamber, the storage chamber having an outlet end with an initially sealed outlet via which a fluid ingredient can be output;- at least one first predetermined breaking point or line configured in or at the storage chamber, and- an actuation mechanism arranged at the storage chamber, the actuation mechanism having at least one activation part that can be displaced relative to the outlet end and by means of which at least one part or section of the storage chamber can be axially displaced in order to activate the at least one first predetermined breaking point or line, on an activation of the applicator. The invention further relates to a method of activating an applicator.

A pump includes a housing having an inlet and an outlet configured to convey fluid, an impeller configured to convey the fluid from the inlet to the outlet, the impeller being arranged on a rotatable shaft, and a balance drum configured to relieve axial thrust. The balance drum includes a rotor rotationally fixedly connected to the shaft, the rotor having a high and low pressure sides, a stator stationary with respect to the housing, a relief passage extending between the rotor and the stator from the high pressure side up to the low pressure side of the rotor, a return passage connecting the low pressure side of the rotor to the inlet. An intermediate passage opens into the relief passage between the high pressure side and the low pressure side of the rotor. A blocking member is configured to influence the flow through the intermediate passage.
