The dosing pump has no on/off-switch and is operated externally via the power supply. To stop the dosing
pump, the power supply must be interrupted, or the metering capacity must be adjusted by turning the
stroke frequency dial to the right to "0 %".
8.1 Setting of flow rate
In dependence to the model variant, the dosing pump has a fixed stroke length and a fixed dosing quantity
per stroke. The dosing quantity is controlled continously variable via the stroke frequency in the metering
capacity of 0 to 100% (see stroke frequency adjustment
a
). The stroke frequency adjustment is ap-
proximately linear in proportion to the conveyed dosing quantity. For the maximum dosing quantity (100%
metering capacity) in dependence of the back pressure refer to the flow rate characteristics. The maximum
and the medium capacity are also indicated on the type plate of the dosing pump.
The actual metering capacity in the respective surroundings may differ from the theoretical capacity. The
stroke frequency adjustment may be adapted by a calibration process to the surrounding (see chapter 12).
