Do not reduce the suction. Reduction of the suction is responsible of the cavitation of the
pump, which causes a loss of efficiency and a rapid wear. Reduction of the discharge
are not advisable, if required, reduction of the capacity can be obtained by means of a
valve installed on the discharge pipe.
Do not loosen the connection of the pump while it’s under pressure.
Do not start and/or use the pump if there are signs of leak in the system.
The working temperatures have to respect the characteristics of the construction
materials of the pump:
0 - 60 °C polypropylene execution (PP)
0 - 80 °C PVDF execution
Do not allow the pump to run dry (Note: the mag drive pump design doesn’tallow the
dry-running functioning because it will damage irrevocably the inner parts of the pump).
An accidental failure can generate sprinklings up to considerable distances. In case of
vibrations or anomalous noises, stop the pump immediately.
Do not pump inflamed liquids.
Do not touch the pump while operating.
Before touching the motor or the bracket switch off the electric current.
3.2 Dry-Running
Fill the pump with water or with the liquid to be pumped before starting the unit. This will
protect the bearings and the shaft of the pump against dry running. Do not allow the
pump to run dry because this can cause serious damages to the internal parts of the
pump due to the lack of the necessary lubrication.
