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 technical data,
suction/discharge side connector), the connector 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.
