6 Commissioning/Start-up/Shutdown
The flow velocity past the motor is defined for the installation conditions, see table
below. Decisive factors are the inside well diameter or the inside shroud diameter,
the operating data and the outside dimensions of the pump
▪ Example: pump set installed in a vertical position above the screen/filter in a well;
values in accordance with the table below.
▪ Example: pump set installed in a horizontal position in a tank, fitted with a
cooling shroud, or pump set installed in a vertical position in a pump sump, fitted
with a cooling shroud; values in accordance with the table below
