8.2 Operation
The MP 1/Redi-Flo2 pump is not designed for continuous operation like for instance remedial pumping.
Continuous operation may reduce the life of the pump.
8.2.1 Setting of pump performance
When the pump speed has been changed, wait a while to let the speed settle at the set level. Then new
adjustments can be made.
8.2.2 Minimumow
To ensure the necessary cooling of the motor, the pump should never be set so low that it gives no water.

can yield. The pump performance must immediately be reduced or the pump must be stopped to avoid
damage to the pump.
8.2.3 After use
After use, switch off the electricity supply to the converter before the motor cable is disconnected from the
converter.
8.3 Performance curves MP 1 / Redi-Flo2 pump
xample
When the static head is 66 m, discharge
of the pump will be 0,34 l/s.
In practice the discharge/pressure will
be less because of losses.
