necessary.

• Use a clean cloth to clean the surfaces in contact with

the shaft seal.

• Mount the counterpart 

604

and its seal 

605

in the shaft

seal holder 

601

inserting the pin 

627

in the slot in the

counterpart.

• Lightly lubricate the shaft 

501. 

Check that the spacer is

512

resting correctly against the circlip 

511

then intro-

duce the jacket 

622

and its seals 

602

623

inside

the front cover 

401a

, the two M5 threads must be posi-

tioned horizontally, with the bigger hole facing upward
(for jacket versions P40 - P60 - P100).

• Slide the rotating part 

697

of the shaft seal and its seal

613

onto the shaft 

501

to reach the side indicated in

the table (against the spacer 

512

for jacket versions

P40 - P60 - P100).

• Tighten the screws 

617

to keep the rotating part 

697

on

the shaft 

501

. Lock the screws with Loctite

®

643* or

equivalent (the screws are accessed 

617

through the

top hole on the front cover 

401a

). Make sure you insert

the rotating part fully against the spacer. Tighten the
second bolt 

617 

by locating it in front of the hole in the

front cover 

401a 

and turning the shaft 

501

for jacket

versions P40 - P60 - P100).

• Insert the shaft seal holder assembly 

601

and the

counterpart 

604

into the strainer 

725

(be careful not to

bump the edge of the shaft seal counterpart 

604

).

• Tighten the 2 screws 

729

and nuts 

730 

on the strainer

725

.

• Slide the strainer assembly 

725

onto the shaft 

501

until

it reaches the front cover 

401a

(be careful with the fric-

tion face of the counterpart 

604

of the shaft seal and

the lip seal 

716

).

Step 12 :

• Screw the 3 screws 

726

.

• Position the washer 

731

against the shoulder of the

shaft 

501

.

• Fit the bearing 

703

on the shaft by hand.

• Push it on with a casing until it comes to bear against

the washer 

731

. Under no circumstances should you

push the bearing onto the shaft without holding the
shaft 

501

.

FAILURE TO FOLLOW THIS INSTRUCTION CAN CAUSE
SERIOUS DAMAGE TO THE INTERIOR OF THE PUMP.

• Position the second washer 

731

against the bearing 

703

.

• Fit the circlip 

537

.

• Clean the surfaces of the cover 

705

and of the housing

725 

with a clean cloth.

• Fit the lip seal 

707

into the cover 

705

.

• Fit the cover 

705 

on the strainer 

725

.

• Screw the 4 screws 

723

.

• Check that the pump rotates freely when turned by hand.

• Replace the pump on the installation.

• Replace the pump mounting screws.

• Couple the pump by placing the coupling sleeve.

• Check the pump alignment (see § ALIGNMENT OF

MOTOR/PUMP AND REDUCTION GEARBOX/PUMP
SHAFTS).
