Axial Position Of The Pump Rotor; Horizontal Installation; Connection Of Support Feet - Calpeda MXV-B Instrucciones Originales De Uso

10.2. Axial position of the pump rotor

MXV(L), MXV(L)4
In the vertical position and from the resting position
(fig.5a), raise the rotor, levering on a pin inserted in the
hole in the shaft, until the pin can be rested under the
coupling (64.22).
In this position (fig. 5b), by tightening the screws (64.25)
uniformly, the shaft (64.00) is locked tight in the coupling.
Remove the pin.
Mount the motor as indicated in section 4.
11. Horizontal installation MXV(L) 50-65-80,
MXV(L)4 50-65-80

11.1 Connection of support feet

For the mounting of the support feet all tour nuts (61.04)
on the tie-bolts (61.02) must be removed (see cross-sec-
tion drawing in section 14.).
ATTENTiON: do not loosen only the two nuts on the
side of the upper cover to which the support foot is to be
attached.
To remove the 4 nuts (61.04) the lantern bracket
(32.00) must be removed. With the pump in the vertical
position, carry out dismantling sequences 1 - 6 in section 9.
Remove the washers (61.03) and attach the support foot
(61.30) on the side of the upper cover (34.02) in the ap-
propriate position depending on the directional arrange-
ment of the pump casing (14.00) suitable for the system:
suction on the left and delivery on the right, or vice-versa
(fig.6)

Fig.6 Orientation of the ports in a horizontally-fitted pump
Do not insert the two washers (61.03) on the support foot
when the tie-bolts (61.02) do not protrude from the nuts
(61.04).
The 4 nuts must be uniformly tightened with alternat-
ed crossover tightening procedure in diametrically
opposite positions. Tightening torque as per section
10.1.
Mount the lantern bracket (32.00) with the coupling
(64.22) and position the pump shaft as indicated in sec-
tion 10.2.
Mount the motor as indicated in section 4, and orientate
the terminal board with respect to the support foot
(61.30) in the position most suitable for the system.
After setting the pump in the horizontal position, fix the
second support (61.30) to the base (61.00), with the
screws (61.30), washers (61.34) and nuts (61.36), and
check for accurate levelling of the installation with re-
spect to the first foot.
12. Spare parts
When ordering spare parts please quote their designation,
