Abstract: Particular techniques involve a device for wetting multiple threads with a fluid, and a dosing pump which is connected to the wetting means by multiple conveying lines. The dosing pump has multiple conveying means for generating multiple dosing flows of the fluid and has multiple pump outlets, to which the delivery lines are connected. The conveying means are formed by at least one planetary gear set arranged between housing plates. To achieve, as far as possible, a uniform throughflow without a significant dead space volume, multiple planet gears of the planetary gear set are guided freely by a centering plate between adjacent housing plates. The planet gears of the planetary gear set have in each case one passage opening, which are connected by a channel system to a central pump inlet. It is thus possible to realize close fits and flushing of gaps.

Abstract: A dynamic mixer for mixing flowable media, which has a mixing chamber in a multipart housing is described. A plurality of inlets and an outlet of the mixing chamber are arranged on the housing, and a mixing shaft having a mixer section projects into the mixing chamber. The mixing shaft is mounted in a sliding bearing in the housing by means of a bearing section and passes through the housing with a drive section for coupling to a drive. To avoid dead spaces within the housing, the housing has a sealing hole for accommodating the drive section of the mixing shaft and a bearing hole for mounting the bearing section of the mixing shaft, where the sealing hole has a greater diameter than the bearing hole in order to accommodate a sealing means.
