In case this is not possible, before the restart of the pump verify / check that:
•
inside there are no incrustations or deposits that could obstruct the impeller and / or prevent its free rotation;
•
the condition of the impeller, the tightening of the ogive, that there is not excessive and non-uniform wear of the
blades at the inlet and outlet and, where present, of the ring or wear plate;
•
the correct tightening of the casing, bearing housing and columns screws (APPENDIX B);
•

If the pump is removed from the system, proceed with the instructions in the "STORAGE" section after having fully cleaned
and dried the hydraulics and all the components in contact with the pumped fluid.
