All figures apply to water at 20 °C.
The suction lift applies to a filled suction line and filled liquid end - when
installed correctly.
* With Sigma types 07120, 07220 and 04350, the valves in the dosing
head are configured as DN 25 (G1 1/2A male). As DN 20 is generally suffi‐
cient for the pipework for these types (see technical data, suction/
discharge side connector), the connector parts that can be ordered with
the identity code (e.g. inserts) are already reduced to DN 20, i.e. DN 20
pipework and accessories can be installed.
