As described on paragraph no. 2
“Disassembling sequence”, unscrew the
connections (POS.1) and remove the
HYDRAULIC PARTS from the MOTOR
PARTS
-
Proceed separately to disassembly the
HYDRAULIC PARTS or the MOTOR
PARTS following the sequence described
on paragraph no. 2 “ Disassembling
sequence ”.
- warning! The disassembly operations of
parts magnetically connected involve great
opposed forces: keep the MOTOR PARTS
fixed on floor during the removing of the
HYDRAULIC PARTS.
-
to facilitate the disassembly operations
keep the pump in vertical position (suction
on top)

-
warning! During the disassembly of the
hydraulic parts do not bump the guide
components
-
warning! After the dismantling of the pump
casing extract together the impeller and the
central disc; extract avoiding radial
movements

-
disassembly the MOTOR PARTS: unscrew
the 4 Phillips drive screws inside the drive
magnet assembly, POS. E in
Fig. 9.1 D
-
warning! During the use of screw driver
inside the drive magnet assembly you must
oppose the magnetic attraction
-
warning! After unscrewing the 4 screw
(POS. E in
Fig. 9.1 D
) insert the punch
φ
<
4mm in one of two extraction holes (POS. D
in
Fig. 9.1 D
) to remove the collar (POS.C in
Fig. 9.1 E
) from the back and to allow the
removing of the drive magnet assembly,
sockets and collar (POS.A, POS.B, POS.C
in
Fig. 9.1 E
) from the motor shaft.

9.2 INSPECTION
Check:
- the pump shaft for cracks and excessive wear
- guide bushing for excessive wear
- counterthrust bushing for cracks or excessive wear
- pump shaft clutch
- that the guide bushing cooling circuit is not blocked
- the impeller, volute and rear chamber for abrasion and corrosion
- that the pressure balancing holes on the impeller blades are not blocked
- for lumps and clusters created by the pumped liquid (especially at the bottom the rear chamber)
