In case of ordinary maintenance (as indicated in paragraph 4.2) the customer is
responsible for the correct assembly and disassembly of the pump. The warranty is no
more valid if the pump is manipulated/sabotaged, the parts used for the maintenance are
not GemmeCotti original or in case of operations not in compliance with the instructions
indicated in this manual. During ordinary maintenance the customer should check the
absence of leakage (through hydrostatic tests, paying attention to respect the NP of
the pump.), the magnet/impeller alignment, the correct shaft positioning, the correct
bearing placement and the right functioning of the pump. For the tightening torque of
the screws please refer to paragraph 4.7. Pay attention also to avoid ruining the o-ring
when mounting it.
4. MAINTENANCE
4.1 General Dispositions
Clean the external surface of the pumps using only antistatic equipment. Every operation
executed on the apparatus has to be done after the disconnection of electric supply.
During the warranty period extraordinary maintenance is allowed only for GemmeCotti personnel
or personnel authorized by GemmeCotti. All the operations described in the paragraphs below
have to be done exclusively by qualified staff and following step by step all the warnings written
in this manual.
Use exclusively a goods lift to move pumps with weight higher than 16 kg. During the
movements of the machine or parts of the machine avoid collisions or falls which can
damage the apparatus.
Before disassembling the parts of the pump, make sure that the dangerous internal
liquids have been removed/washed. The pump has to be drained and decontaminated.
Pay attention that some internal liquids can have dangerous reactions in contact with
water.
During the operations of unloading of dangerous liquids make sure that situations of
danger for people or environment don’t occur.
4.2 Inspections
In general mag drive pumps do not need a “routine” maintenance and most of all they don’t
require frequent dismantling. However periodical inspections are advisable to verify the state of
wear of the impeller, the shaft, the o-rings and the bearings and if the general conditions of the
internal parts of the pump are good.
