RE

‐

ASSEMBLY

 

Before

 

starting

 

assembly

 

of

 

the

 

pump

 

consult

 

the

 

sectional

 

drawing.

 

Respect

 

screws

 

and

 

bolts

 

tightening

 

torques.

 

Check

 

that

 

threads,

 

bearing

 

and

 

gaskets

 

surfaces

 

are

 

clean.

ASSEMBLY

 

OF

 

BEARING

 

BRACKET

 

1.

 

Clean

 

with

 

care

 

the

 

inside

 

of

 

the

 

bearing

 

housing

 

3200

 

and

 

the

 

surface

 

of

 

ball

 

bearings

 

housings.

 

2.

 

The

 

following

 

methods

 

are

 

recommended

 

to

 

fit

 

the

 

bearings

 

on

 

the

 

shaft

 

:

 

1

rst

 

method

 

:

 

Use

 

a

 

hot

 

plate,

 

hot

 

bath,

 

oven

 

or

 

an

 

induction

 

heater

 

to

 

heat

 

the

 

bearing

 

race

 

so

 

that

 

it

 

can

 

be

 

easily

 

slided

 

onto

 

the

 

shaft.

 

It

 

will

 

then

 

shrink

 

and

 

grip

 

the

 

shaft.

 

Heating

 

temperature

 

should

 

never

 

exceed

 

100°C.

 

2

nd

 

method

 

:

 

Press

 

the

 

bearing

 

onto

 

the

 

shaft

 

using

 

a

 

hand

 

press.

 

Make

 

sure

 

the

 

force

 

is

 

applied

 

on

 

inner

 

bearing

 

race.

 

Take

 

care

 

to

 

avoid

 

damaging

 

the

 

shaft

 

or

 

the

 

bearing.

 

3.

 

Slide

 

the

 

assembly

 

in

 

the

 

bearing

 

housing.

 

4.

 

Install

 

bearing

 

cover

 

and

 

tighten

 

fastening

 

screws.

ASSEMBLY

 

OF

 

MECHANICAL

 

SEAL

 

Assembly

 

is

 

performed

 

in

 

the

 

reverse

 

steps

 

of

 

dismantling.

 

Using

 

the

 

section

 

drawing

 

of

 

the

 

pump

 

will

 

be

 

necessary.

 

Extreme

 

cleanliness

 

is

 

required

 

when

 

installing

 

the

 

mechanical

 

seal

 

onto

 

the

 

shaft

 

sleeve.

 

Avoid

 

damaging

 

the

 

seal

 

faces

 

and

 

the

 

O’Ring.

 

(shaft

 

must

 

be

 

free

 

from

 

scratches,

 

burrs,

 

…).

 

It

 

is

 

recommended

 

to

 

apply

 

lightly

 

grease

 

or

 

a

 

neutral

 

oil

 

to

 

ease

 

assembly.

 

Make

 

sure

 

the

 

leap

 

seal

 

is

 

installed

 

in

 

the

 

indicated

 

direction.

Mechanical

 

seal

 

is

 

set

 

per

 

construction.

 

All

 

gaskets

 

should

 

be

 

replaced

 

by

 

new

 

ones

 

before

 

assembly.

 

Make

 

sure

 

PFTE

 

and

 

fiber

 

based

 

gaskets

 

are

 

not

 

bent

 

or

 

broken

 

when

 

handled

 

and

 

installed.

MOTOR

 

In

 

order

 

to

 

ensure

 

an

 

optimum

 

lifetime

 

of

 

the

 

integrated

 

motor

 

a

 

minimum

 

maintenance

 

is

 

necessary

 

:

 

clean

 

cooling

 

fins

 

regularly,

 

check

 

coupling

 

alignment

 

(if

 

any),

 

check

 

cable

 

gland

 

tightening,

 

…

 

Ball

 

bearing

 

lifetime

 

depends

 

on

 

axial

 

and

 

radial

 

forces

 

applied

 

on

 

motor

 

shaft

 

therefore

 

on

 

the

 

pump

 

design

 

(close

‐

coupled

 

pump,

 

pump

 

sets

 

with

 

elastic

 

coupling,

 

…).

 

Motor

 

can

 

be

 

fitted

 

with

 

lifetime

 

lubricated

 

ball

 

bearings

 

(identified

 

ZZ

 

or

 

2Z)

 

or

 

greased.

 

Greasing

 

nipples

 

are

 

located

 

at

 

the

 

ball

 

bearings

 

and

 

re

TIGHTENING

 

TORQUES

 

Tightening

 

torques

 

depend

 

on

 

the

 

material

 

used

 

in

 

the

 

assembly

 

and

 

on

 

the

 

type

 

of

 

lubricant

 

that

 

is

 

used.

 

Refer

 

to

 

applicable

 

regulation

 

to

 

know

 

the

 

tightening

 

torques

 

for

 

the

 

fastening

 

of

 

cast

 

iron

 

or

 

stainless

 

steel

 

made

 

flanges.

 

The

 

values

 

given

 

below

 

should

 

be

 

only

 

indicative.

 

If

 

real
