Operation of the pump in the case of external flow

The pump can start and be operated in the case of positive external flow (generator
operation) with up to 100 % of its maximum flow rate (e.g. pumps connected in
series)
The pump can start and be operated in the case of negative external flow (turbine op-
eration) with up to 20 % of its maximum flow rate.
NOTICE
The pump may still be live even in voltage-free state. The driven rotor induces a
voltage within the pump. This results in undefined flashing of the LEDs. This be-
haviour stops as soon as the external flow stops or when the pump is connected
to the power supply.
