CALPEDA B-N4 65-315A [11/44] Pump motor unit with rex viva

CALPEDA N 40-125F/A [11/44] Pump motor unit with rex viva

Control procedure must be performed at 4 diametri-

cally opposed, equidistant points on the periphery

(fig. 6A).

For adjustment, loosen or tighten the screws where

necessary in order to move the position of the sup-

port feet on the baseplate and to add calibrated pla-

tes between the feet and baseplate wherever these

may be required.

Make sure the rotor turns freely when moved by

hand.

The alignment must be rechecked once the unit

attains its operating temperature.

While the foundation is still new and the unit has

not been fully tested under all operating conditions,

verification of alignment must be repeated at regu-

lar intervals and, if necessary, alignment procedure

must be carried out again.

4.2. Pump motor unit with Rex-Viva

coupling

Remove the coupling guard, loosen the screws and

remove the half-couplings.

With a dial indicator or straight edge, check the

coaxial alignment of the hubs fixed at motor shaft

and pump shaft.

Control procedure must be performed at 4 diametri-

cally opposed, equidistant points on the periphery

(fig. 6B).

For adjustment, loosen or tighten the screws where

necessary in order to move the position of the sup-

port feet on the base-plate and add calibrated pla-

tes between the feet and base-plate wherever

these may be required.

Reassemble the half-couplings following this

sequence:

- Insert the two central screws of the first half-cou-

pling.

- Insert and tighten the two central screws of the

second half-coupling at the required torque.

- Tighten the two central screws of the first half-cou-

pling at the required torque.

- Insert the two lateral screws of the first half-cou-

pling.

- Insert and tighten the two lateral screws of the

second half-coupling at the required torque.

- Tighten the two lateral screws of the first half-cou-

pling at the required torque

- Repeat the sequence for the last screws.

Tighten the screws at the torque advised by the

manufacturer on the coupling instructions.

Make sure the rotor turns freely when moved by

hand. The alignment must be rechecked once the

unit attains its operating temperature.

While the foundation is still new and the unit has

not been fully tested under all operating conditions,

verification of alignment must be repeated

at regular intervals and, if necessary, alignment

procedure must be carried

out again.

ATTENTION: poor baseplate installation and

misalignment of units or faulty connection of

pipes will cause vibration and early wear of ela-

stic coupling inserts, bearings, the seal and other

internal parts (see also sections 2.1., 3.1., 4.1.).

4.3.

Extra support for bearing housing

In order to reduce problems caused by expansion

or residual external stress in pipes, N, N4 pumps

may be fitted with a support and anchoring foot

which will help to impede variation of alignment to

an extent that might cause damage.

The recommended dimensions are indicated (in

mm) in fig. 7.

During alignment operations, before connection of

pipe, leave support foot screws untightened so as to

avoid stress by pipe strain or shifting of axis height.

The support foot must be placed on the base surfa-

ce and brought into contact with the support itself

only after completion of alignment procedure, which

must be re-checked after tightening the screws
