CALPEDA MXV-B 25-204 [7/32] Spare parts

In the case of water containing chloride (chlorine or sea water)

the risk of corrosion increases in stagnant water conditions

(also with an increase in temperature and decrease of pH

value). In these cases, if the pump remains inactive for long

periods, it must be emptied completely.

For good measure, as for temporary operation with dirty liquids,

run the pump briefly with clean water to remove deposits.

When the pump remains inactive it must be emptied

completely if there is a risk of freezing (fig.4).

Before starting the motor again fill the pump completely with

liquid (see section 6.2.) and make sure the shaft is not jammed

by encrustation, sticking of the faces of the mechanical seal or

other causes. In the event that the shaft cannot be moved by

hand, the pump has to be dismantled and cleaned.

Disconnect electrical power before any servicing

operation and make sure the pump cannot be

accidentally switched on.

8. Dismantling

Before dismantling, close the gate valves in the suction and

delivery pipes and empty the pump casing (fig. 4).

For dismantling and re-assembly refer to the section drawing.

By removing the nuts (61.04) from the tiebolts (61.02) the motor

can be taken out complete (99.00), with all internal parts of the

pump without removing the pump casing (external jacket 14.02)

from the pipeline.

8.1 Replacing the mechanical seal

Make sure the spring of the new mechanical seal is set with

the direction of the winding suitable for the direction of rotation

of the shaft: i.e. clockwise when seen from the stationary ring.

Make sure that all parts with which the mechanical seal comes into

contact are perfectly clean and free from any burr or cutting edges.

The seal rings in EPDM (Ethylene-Propylene) must never

come into contact with oil or grease. To facilitate the mounting

of the mechanical seal, lubricate the shaft, the seating of the

stationary part and the seal rings with clean water or any other

lubricant compatible with the material in which the seal rings

are made.

Use every precaution so as not to damage the seal surfaces

with blows or angular impact.

9. Remounting

To remount the components follow the dismantling procedure in

inverse order (see section 8.).

When inserting the complete motor (99.00) with the internal

parts of the pump into the external jacket (14.02), make sure

that the first stage casing (25.01) in the suction casing (16.00)

and the stage casing with bearing (25.03) in the first stage ca-

sing (25.01) are correctly inserted.

Check the state of the o-rings (14.20) and replace them of they

are damaged. Make sure that the o-rings (14.20) are correctly in-

serted on their

seats on the pump casing (14.00) and upper cover

(34.02). Lubricate

the seal rings with clean water or any other com-

patible lubricant.

9.1. Tightening torque

impeller nuts (28.04) nuts (61.04) on tie-bolts

8 Nm 50 Nm

ATTENTION: the nuts (61.04) on the tie-bolts (61.02) must be

uniformly tightened with alternated crossover tightening pro-

cedure in diametrically opposite positions.

10. Spare parts

When ordering spare parts please quote their designation, position

number in the cross section drawing and rated data from the

pump name plate (type, date and serial number).

Any pumps that require inspection/repair must be

drained and carefully cleaned inside and outside

before dispatch/submission.
