8 – WARRANTY
The pump is covered by warranty for a period of two years from the
date of purchase by the final user. In the absence of documentation
proving the date, the warranty period starts from July 1st of the year
of manufacture, indicated on the ratings plate. The warranty expires
in any case after 3 years from July 1st of the year of manufacture.
The warranty covers all manufacturing and material defects confirmed
by the manufacturer and consists in the repair or free replacement of
the pump by the manufacturer. Any repairs performed under warranty
do not modify the expiry date of this warranty.
The warranty does not cover damages caused by improper use, by
faulty electrical supply, by use that is not in conformity with the
instructions contained in the "user and maintenance manual".
Moreover, it does not cover any damages caused or tampering
performed by the user, maintenance operations performed incorrectly
(also with the use of non-original spare parts) and wear related to
normal use (in particular, seals, bearings, capacitors, brushes).

9.1 – DISASSEMBLING THE HYDRAULIC PART
Before disassembly and assembly operations, disconnect
the equipment from the power supply to prevent accidental
starting with moving parts exposed.
Internal parts can have sharp edges; therefore, they should be
handled with care wearing appropriate personal protective
equipment.
Before disassembly discharge any pressure present inside the
pump, wait for it to cool, empty it and dispose of the liquid contained
appropriately; if the pump is used for dangerous substances comply
with the safety regulations in force for handling of these substances.
The references below can be found in Figs. 1, 2, 3A, 3B, 4 and 9
according to the indications provided in paragraph 3.2.
- Unscrew the screws (ref. 30 or ref. 31) of the cover (ref. 11).
- Remove the cover.
- Remove the O-ring (ref. 12).
- Extract the impeller (ref. 13) as follows:
brass models type 20-25-30-35-40: the impeller slides on the shaft (ref.
64), it can be extracted simply using your fingers;
brass models type 50 and all stainless steel models: the impeller is
forced onto the shaft; to remove it use an extractor with appropriately
shaped claws (fig. 7); the hub of the impeller is provided with two
projections for this purpose (fig. 7); for stainless steel models type 20 use
the two projections present on the side of the pump body (fig. 7) for
extraction.
- Remove the tab (ref. 15).
- Extract the pump body (ref. 10) from the shaft.
- (Only for brass models type 20) extract the counterflange (ref. 5) from
the pump body and remove the gasket (ref. 8).
9.2 – ASSEMBLING THE HYDRAULIC PART
(For brass models type 20, first insert the counterflange ref. 5 and position
the gasket ref. 8);
- Insert the tab (ref. 15) in its seat
national
- Insert the pump body (ref. 10) along the shaft (ref. 64)
- Position the O-ring (ref. 12) in its seat on the pump body
Models with sliding impeller
- Insert the impeller (ref. 13) over the shaft using your fingers.
- Fit the cover (ref. 11) and insert the screws (ref. 30 or ref. 31), gradually
and alternately tightening opposite screws.
Models with forced impeller
The impeller is inserted using a hollow bar with internal diameter slightly
larger than that of the shaft.
- To prevent damaging the bearings, first remove the fan cover (ref. 2) and
place the back of the shaft (the end on which the motor fan ref. 1 is
mounted) on a soft metal surface.
- Striking the impeller (ref. 13) in a central position using the hollow bar and
a hammer, move it towards the wearing surface, leaving 0.1 mm
clearance.
- Fit the cover (ref. 11) and insert the screws (ref. 30 or ref. 31), gradually
and alternately tightening opposite screws.
- Strike the back of the shaft with a punch and hammer.
- Check that the impeller rotates freely rotating the motor fan (ref. 1) and fit
the fan cover (ref. 2).
9.2.1 – REPLACING THE LIP SEAL
(brass models type 20 and 50)
- Remove the worn lip seal (ref. 67) from its seat (located in the
counterflange ref. 5 for models type 20 and in the pump body for models
type 50) striking it using a solid drift of suitable dimensions as shown in
Fig. 23. (type 20) or Fig. 25 (type 50).
-Take an identical new lip seal and place it against the mouth of its seat as
shown in Fig. 24 (type 20) or Fig. 26 (type 50) facing in the correct
direction (the spring must be facing the inside of the pump).
- Insert the lip seal in its seat striking it using a solid drift with a slightly
smaller diameter to that of the outer diameter of the lip seal until it has
been completely inserted.
9.2.2 - REPLACING THE LIP SEAL
(brass models type 25-30-35-40)
The pump body is produced in two pieces: pump body (ref. 10) and rear
internal part (ref. 65), which is inserted into the pump body (Fig. 2 shows
the two parts disassembled, Fig. 10 after assembly). To replace the lip
seal (ref. 67) the rear internal part must be extracted from the pump body.
- Place the edge of the pump body on two surfaces made of soft material
(i.e. wood or aluminium) or any other material, provided that two pieces of
