  • the preparation pump in Figure 6 is also a multiple pump with a total eight pairs of gears and eight pump outlets. Opposite the in FIG. 5 embodiment protrudes in an axial extension of the Drive shaft 108 a separate mixing shaft 124 into the mixing chamber 104.
  • the mixing shaft 124 is through a transmission gear 123 with the drive shaft 108 connected. Thus, the mixing shaft 124 is shared by the motor 117 driven by the drive shaft 108. On the circumference of the mixing shaft 124 are in Several mixing elements 125 are arranged one behind the other. The Mixing elements 125 correspond to several on the pump housing 101 attached mixing elements 126. The mixing elements 126 are stationary.
  • the mixing shaft 124 By rotating the mixing shaft 124, the subcomponents A and B of the Preparative, which via the inlet openings 105 and 106 in the Mixing chamber 104 are introduced, mixed.
  • the Pump inlet 103 formed At the end of the Mixing chamber 104 through which partial components A and B flow is the Pump inlet 103 formed, which is the outlet of the mixing chamber 104th forms.
  • the sub-pumps 122 or the pump inlet 103 thus get a fresh one emulsified preparation.
  • the sub-pumps 122 deliver metered Volume flows of the preparation to the pump outlets 114. From However, the preparation passes the pump outlet to one of the Preparation pump downstream wetting device.
  • a transmission gear 123 is provided.
  • the mixing shaft 124 can be driven by the drive 117 at a higher speed drive so that an intensive and even mixing of the Partial components of the preparation are carried out prior to delivery.
  • the mixing elements formed on the mixing shaft can, for example, by Perforated disks, slotted disks or formed by pins.
  • the mixing elements shown as Figure 6 can be arranged.
  • Preparation pumps can be used with any wetting device be combined. Especially with the aforementioned pen and Nozzle preparation is a metered delivery of the preparation pump advantageous.
