All figures refer to water at 20 °C.
The suction lift applies to filled suction line and filled liquid end - when
installed correctly.
* For Sigma types 07120, 07220 and 04350 the valves in
the dosing head are of type DN 25 (G1 1/2). As for these
types of pipes, DN 20 is generally sufficient (see tech‐
nical data, suction/discharge side connector), the con‐
nector parts that can be ordered under the identity code
(e.g. inserts) are already reduced to DN 20, i.e. piping
and accessories can be installed in DN 20.
