ELETTROPOMPE
6.4
Stop the pump/electropump
– If the non-return valve is not present, close the shutter on the delivery pipe.
– If there is no foot valve present, close the intake shutter.
– Disconnect the electric power supply to the pump engine.
6.5
Storage
Pump installed, not in operation but ready to be started up: operate the pump for at least 10 minutes once a month.
Pump removed from the system and put into storage: clean the pump and protect its surfaces from corrosion by
applying appropriate products.

Maintenance
7.1
General information
In the event it is necessary to perform any type of maintenance, the following precautions must be followed:
–
disconnect the pump motor from the electrical system;
–
Ensure the status of the unit is safe and prevent it from being started up again by accident.
–
wait until the temperature of the liquid is such not to create a danger of burns;
–
if the liquid handled by the pump is harmful for one's health, it is indispensable to observe the following warnings:
= Abide by the relevant legal regulations;
= the operator must wear suitable individual protection devices (mask, goggles, gloves, etc.);
= the liquid must be carefully collected and disposed of with respect for current law;
= the pump must be washed inside and out, disposing of the residues as said above.
7.2
Components subject to wear
The components subject to routine wear are: the bearings, gaskets, O-rings, rings and mechanical seal.
The status of components subject to wear should be checked at least once every 15,000 hours of operation,
or every 2 years, replacing them if necessary.
However, we recommend replacing these components every time the pump is disassembled / reassembled.
7.3
Disassembly/assembly
Refer to figure 6.
Disassembly: unscrew the nuts (04), remove the tie rods (09), and remove the suction casing (02) with the bushing
support (01). Unscrew the ring nuts (43-44), remove the impellers (06) and the diffusers (40), the stage casings (39)
and the spacers (07) and the keys (08). Now remove the last diffuser (36), the drum (13) and the delivery body (10).
Remove the Seegers (26), the covers (22) and then remove the shaft (25) equipped with bearings.
Assembly: proceed as above in reverse order. The tightening torque for the tie rods is 140 Nm.
8.
Decomissioning and disposal
At the end of the operating life of the pump/electropump or any of its parts, it must be disposed of in observance of
current regulations. This is also valid for the liquid contents, with particular regard if classified toxic or harmful, which
must be drained either in the case of demolition or maintenance, proceeding as follows:
– under the drain plug, provide a collection container or allow the liquid to drain freely according to its characteristics;
– unscrew the lower drain plug and the upper loading plug and let drain completely.
– Proceed in a similar manner for any oil contained in the bearing support (optional).
