8.1. Routine maintenance

OFF
Before
disconnect the power supply and make sure
EN
that the device could not accidentally operate.
For good measure, as in the case of temporary
operation with dirty liquids, run the pump
briely with clean water to remove deposits.
When the pump remains inactive it must be
emptied completely if there is a risk of freezing
(par. 12.3 ig. 4).
To empty completely the NMD and C 16 pumps it is also
necessary to take out the delivery casing (20.00/14.00)
by removing the screws (20.12/14.24).
Before restarting the unit, check that the shaft is not
jammed and ill the pump casing completely with liquid.
8.2. Dismantling the system
Close the suction and delivery gate valves and drain
the pump casing before dismantling the pump.
8.3. Dismantling the pump
OFF
Close the suction and delivery gate valves and drain
the pump casing before dismantling the pump.
For dismantling and re-assembly see construction in
the cross section drawing.
With the NM, C, pumps the motor can be taken out, by
remowing the screws (14.24), complete with impeller
without removing the pump casing and the pipes.
With NMD pumps it is also necessary to take out the
pump casing (suction casing 16.00 or delivery casing
20.00) by removing the screws (20.12).
8.4. Pumps with IP 55 protection (Special con-
struction)
OFF
To always assure IP 55 degree of protection, it is
necessary to check the following points:
- Before starting the motors, carefully control the
position of the gasket between terminal box and
its cover. For cable of small size, use a protective
covering between cable and cable gland.
- When disassembling the end shields of the motors,
restore the existing joint using the sealing glue
LOCTITE type 510 or other equivalent sealing
system, if any, and check the perfect assembly of the
sealing ring on the shaft.
