All performance data applies to water at 20 °C.
The suction lift applies when the suction line and liquid end are full and correctly installed.
* Sigma types 07120, 07220 and 04350, the valves used in the liquid end are DN 25 (G1
1
/
2
). Since DN 20 is usually adequate for
this tubing (see Technical Data, connection-suction/discharge side) the connector parts to be ordered by Identcode (e.g.
washers) have already been reduced to DN 20, i.e. tubing and accessories can be DN 20.
