recordPump_DN50_H1_10

Pump with head 1 to 10.8m and 11.5m^3/h volume flow (Wilo Stratos 50/1-10)

Extends from PumpBaseRecord (Definition of pump data).

Information

Dimension estimate, but inaccuracies occur due to lack of information in the data sheets.

Espacially because of missing information of upper and lower limit of pump speed.
