washer (pos. 58) and a self-locking nut (pos. 75).
I) Put the support of the bearings onto the flange (51) and fix it with the three screws (pos. 49)
positioned on the flange. Then unite the whole group with the intermediate adaptor of aluminium
(pos. 39).
11) Put the motor onto a plane with the shaft turned upwards and if this should not be possible due to the
excessive length of the pump, create a rotor support system so that the rotor does not suffer any
deformation. Before putting onto the stem the rotating guide bush(es) (pos. 16) and the coating (pos. 8)
in case of the CLV and CGV series you have to fix the intermediate adaptor (pos. 39) on the motor with
the three appropriate screws (pos. 2). The machines of the CMV and of the CLV series include a rubber
deflector (pos. 4), which has to be mounted before the assembly of the column. If the pump belongs to
the CGV series, please prepare and grease the V-ring of the vapour seal, provided that the machine is
equipped with it. The following phase is dedicated to the positioning of the immersion tube and of the
support plate (pas. 3) On the pumps with an axial length of more than 2000 mm has to be mounted a
coating, which covers the transmission organ, proceeding segment per segment (method to be used
also for the assembly of the various elements that compose the column.)
Insert static guide bushes into relative housings (pos. 15 or 66).
Please proceed with care and do not forget to apply the O-rings (pos. 73) and the spacers (pos. 35 or
64).
12) Position the impeller (pos. 21); tighten (clockwise thread) the fixing nut (pos. 20) with a pipe wrench of
22 mm. (On some impellers you have to use a fixed wrench of 32 mm). It is very important to place the
O-rings (pos. 18-19), since they protect the shaft.
13) Put the gasket of the body (pos. 23) into its site.
14) Introduce the pump body (pos. 22) after having introduced into the appropriate sites the o-rings, which
protect the ties.
Tighten the nuts (pos. 9) by means of a pipe wrench of 18 or 22 mm (fig. 2). Interpose the o-rings (pas.
10) between the covered nuts and the body.
15) The last assembly phase is dedicated to the positioning of the delivery tube (26) and the eventual
fixing of flow fittings (pos. 60), if present.
Useful indications
The assembly and disassembly operations of the pump can be performed exclusively by persons
who have got basic mechanical knowledge and skills. For a better understanding of the
characteristic features sufficient notions on the materials, which are used for the construction of the
machine, are indispensable.
RECOMMENDED SPARE PARTS
To determine the minimum quantity of spare parts, which should be available for eventual replacements,
please take into consideration the operating conditions (more or less heavy) and the number of
interchangeable units installed on the plant.
For each pump we normally advise to keep the following pieces on store:
a) One impeller (pos. 21) with its locking nut (pos. 20).
b) One rotating bush (pos. 16) and one fixed bush (pos. 15).
For the CGV series, if intermediate stages are foreseen, you should also keep on store two static bushes
(pos. 66) and two rotating bushes (pos. 69).
c) A complete set of gaskets (for the CMV and CLV series pos. 4-10-11-13-14-18-19-23-28-30-36-47-48.
For the CGV pumps 10-11-13-14-18-19-23-23-28-30-36-47-48-68-71-73).
d) A shaft with its coating (pos. 7-8).
e) For the CGV series a couple of bearings (pos. 53-54) and of sealing rings (pos. 50-55).
f) Still for the pumps of the CGV series, if equipped with a vapour seal, have to be kept on store a rubber
cap (pos. 41) a stationary PTFE ring (pos. 42) and a V-ring (pos. 43).
g) If a closed impeller is mounted, it is important to keep available as spare parts a PTFE C-G wear ring
(pos. 77) and its locking screws (59).
