5 Functioning
AL HPM
Frequency converter (Only on HPM-M15)
The frequency converter used is the Danfoss FC 300. Details of the frequency converter are given in the separate operating
instructions from Danfoss.
Drive
The power is transmitted from the electric motor to the drive shaft via a three-phase motor. Details of the drive are included in
the separate operating instructions for the multi-stage centrifugal pump LKH-112.
Axial face seal
Details of the axial face seal are included in the separate operating instructions for the multi-stage centrifugal pump LKH-112.
Injector
The injector allows the powder to be drawn into the fluid and generates the preliminary mixing of the two components.
It consists of a removable housing with a central suction pipe through which the component from the funnel is blended.
The sub-flow from the second stage of the pump serves as the propellant medium for the injector, which is made possible
via the small recirculation pipe (see Figure 5).
NOTE: HPM-S15 is supplied WITHOUT inlet valve.
