Metering rates

The reproducible metering accuracy is approx. ± 3 % at a minimum 30% stroke length under
invariable conditions.
Due to the characteristics of the pump, higher output can be produced until the operating
temperature is reached.
Accurate metering can be achieved by observing the following points:
a) All metering output data refer to measurements with water at 20 °C as well as a constant
supply voltage and a warmed-up operating condition of the metering pump.
b) If there is pre-pressure (max. 0.8 bar) on the suction side, the pressure difference
between the suction and the pressure sides must be at least 0.1 MPa (1 bar). The water
column on the metering pump must be protected by an appropriate valve arrangement.

Metering stroke adjustment may only be performed with the pump running if the stroke
adjusting screw is enabled.
