2 SAFETY WARNINGS

When the pump is working the following occurs:

- Electric parts are in tension.

- Mechanical parts are moving.

- Pump body, pipelines and articulations are under internal pressure. Therefore do not remove any

protection or locking, do not loosen screws or clampings, as this can cause serious damage to

persons or objects. The clamp joining the pump casing and the lantern bracket must be well tightened

and it should not be easily unscrewed by hand. The tightening of the clamp must be carried out by

means of a spanner and NOT by hand.

- Non-observance of inspection and maintenance can cause damage to persons and objects,

especially when dangerous or toxic liquids are pumped.

- When pumping liquids at a temperature over 60° C, adequate protection and warning signals are

required.

- When you buy a pump with bare shaft, motor coupling operations have to be carried out according

to technical directions and law, providing adequate protections for joints, gear belts, etc.

- Operations on the electric parts have to be carried out by skilled personnel, according to technical

directions and law, on authorization of the responsible installer.

- Installation must ensure an adequate ventilation, in order to cool the motor, as well as enough

space for maintenance operations.

- Before carrying out any operation which requires to disassemble the pump (inspection, cleaning,

seal replacement, etc.), the following preliminary operations have to be carried out:

switch off the motor and disconnect electric power;

close valves on suction and outlet pipelines, in order to avoid the risk of inundation;

use adequate protections for hands and face, if the pump contains liquids which are injurious to

health (for example acids, solvents, etc.);

considerwhethertheliquidwhichowsoutofthepumpwhendisassemblingisdangerousand

arrange for adequate safety measures.

Pay the utmost attention to text blocks indicated by

this symbol.

Danger: failure to comply with these warnings can

cause serious harm to persons and/or objects.

Danger: only qualied personnel can carry out opera-

tions on the electrical part.

4 GOODS TRANSPORTATION, RECEIVING AND TRANSFERRING

4.1 TRANSPORTATION

Thepackings of allpumpsmanufacturedbyC.S.F.InoxS.p.A.are dened whenplacingthe

order. Unless prior arrangements are given, goods will be packed only for transit conditions

and not for long-term storage; in case it should be necessary to store the pumps outside,

you are requested to cover the pumps appropriately in order to protect the electrical parts

(motor) from rain, dust, humidity etc.

4.2 RECEIVING

WARNING Whenreceivingthegoods, thewholenessofpackingmustbeveried,inorderto

identify possible damage to the content during transportation and to claim them immediately

to the carrier. Should any damage be ascertained, the following procedure must be observed:

- collect the goods with reservation;

- take the necessary pictures showing the damage;

- notify the carrier of the damage undergone, by registered airmail, sending at the same time

the pictures taken to show the damaged pieces.

4.3 TRANSFERRING

Carry the packed pumps as close as possible to the place of installation by means of ap-

propriate lifting devices and unpack them. During this operation take care, as unsteady parts

could fall down.

The material used for packing (wood, paper, cellophane, etc.) should be properly gotten rid

of, according to the corresponding rules in force in the receiver’ s country. After unpacking

the pump, use special lifting belts and move the pump-motor set to the place of installation;

never use the eyebolts on the motor to move the pump, as the eyebolts are for moving the

motor only. In versions complete with shroud, take the shroud off before moving the pump-

motor set, in order to avoid damage.

7 SOUND PRESSURE LEVEL

The sound pressure level of centrifugal pumps is the following (see table):

The measurement has been made by means of a sound level meter placed 1 m from the pump and

at a height of 1.6 m from the ground.

Thepreliminaryconditionisthatthepumpisxedcorrectly;theabove-mentionedvaluesdonottake

intoaccountexternalnoisesources(e.g.valves,abrupthydraulicdeections).

8 INSTALLATION - CSK SERIES

The pump/motor set is aligned on the base at C.S.F., before delivery.

After installation has been performed, bounding the set to the foundation and the suction and outlet

pipelineshavebeenconnected,alignmentmustbeveried.

Before starting the unit, install a protective joint cover; it must be removed by specialised personnel

to perform inspections and/or maintenance only after having stopped the unit and disconnected

electrical power.

Warning: Misalignments and forcing cause stress and vibrations on transmission causing wear and

tear and premature breakage of the joint and bearings.

8.1 TYPE "A" ELASTIC COUPLING ASSEMBLY INSTRUCTIONS

1. ASSEMBLING THE HUBS

Oncethehubshavebeenttedontheshafts,andpriortoliningthemup,donotforgettoleavethe

attachment ring fastened onto one of the hubs. Check the pressure setscrews on the hubs are tight.

If the coupling is used in Ex. hazardous areas, the pressure setscrews should be additionally secured

against spontaneous loosening in the attachment of the hub to the shaft; for example, using Loctite

(medium strength) or similar.

2. RADIAL ALlGNMENT

The radial alignment is controlled with a rule or a dial indicator or laser. By resting the rule on the

peripheryofthehubsandmatchinguptwooppositeteeth,youwillhaveasufcientlybroadlineof

contact to check they match up throughout their surface area. Better alignment precision is obtained

with the help of a dial indicator or laser (keep to radial tolerance Y).

3. AXIAL AND ANGULAR ALlGNMENT

Position the hubs at distance E, as for Table 1. Using the thickness feelers, you can control the

gap between hubs, measurement E (keep to axial tolerance X). It is advisable to check the values

of measurement E in three positions (O-90-180 degrees), as this will ensure more precise angular

alignment (keep to angular alignment Z).

4. ASSEMBLING THE ELASTIC INSERT

Once the two hubs have been aligned, proceed to assemble the elastic insert in the slots formed by

the parallel teeth. If the radial and angular alignment is correct, the ends of the elastic insert, once

closed, should match up intheir development and width. The elastic insert has two types of housing:

a through housing, with dual inlets, for horizontal work, and a single-inlet housing for vertical work.

5. ASSEMBLING THE RING

Oncetheelasticinserthasbeentted,theretentionringcanbeinsertedmanually,bymatchingup

one of the two reference Iines on the outside of the ring with the insertion grooves on the elastic insert.

Using a nylon mallet, install the retention ring, tapping alternately on each side of the two areas of

the reference marks, until the ring's lugs are coupled into the central housings of the elastic insert.

6. SECURING THE RING

Once the ring has been installed on the elastic insert, it needs to be fastened by inserting the two

set screws (Tab. 2) into the threaded housings, which match up with those for the elastic insert. We

recommend securing the tightness of the setscrews by applying Loctite (medium strength) to the

screw-threading. Any potential axial displacement of the ring, due to misalignment of the equipment,

is thereby secured.

p. 8

7. DISASSEMBLY

Remove the two set screws from the ring. Shift

the ring by tapping it on the side with a nylon

hammer in the areas the pins (reference lines)

are housed.

8.3 SUCTION AND INFLOW CONDITIONS

(NPSH = Net Positive Suction Head)

NPSH of system (available NPSH)

In order to ensure that pump operation is free from cavitation, it is essential to observe the maximum

permitted suction lift ha geo max or the minimum allowable head hc geo min.

NPSH of pump (required NPSH)

The centrifugal pumps can operate correctly only if vapour has not formed inside. For this reason

the static head at the reference point for the NPSH is the centre of the impeller, that is the point of

intersection of the pump shaft axis with the vertical plane that passes through the external points

of the blade inlet corners.

NPSH is the value required by the pump, expressed in metres, obtained from the performance curve.

In practice 0.5 m should be added to this value as a safety margin.

8.4 PIPING

In order to prevent the creation of harmful strains, the suction and discharge pipes must be con-

nected to the pump ports without the use of force. These pipes must also be supported indepen-

dently avoiding causing stress on the pump. The internal diameter must be the same size as the

pump connections. It must in any case not be smaller to avoid head loss and/or poor performances.

Always use elbows with large radius. If the pipe diameter changes along the line, use reduction

cones, choosing the ones that are most suitable to avoid any formation of air pockets (Fig. 1).

YES

Fig. 1

The suction pipe must be as short as possible and rise as it moves towards the pump if it is sucking

from a tank (Fig. 2). If on the other hand the pump is below the level of the liquid, the pipe should

descendslightly(Fig.3).Ifthepumpisusedfortransportinghotliquids,texpansionjointstocom-

pensate any expansion of the piping. The maximum velocity of the liquid in the suction pipe must

not be greater than 3 m/s. Velocities between 1 and 2 m/s are recommended. The suction pipe must

be designed in such a way as to prevent air from entering the pump.

p. 10

For this reason, when sucking from a tank located at a lower level, the pipe must reach below the

free surface of the liquid. In order to prevent the formation of vortices and avoid the risk of sucking

in air, always keep a minimum head at the pipe inlet (h. min.) equal to at least the dynamic head

plus a safety margin of 0.1 m (Fig.2).

Va2

hmin = m

V = m/s

h min = + 0,1

In order to prevent the formation of vortices when it is not possible to observe the values of minimum

availablehead,itispossibletotcrossesinthepiping.Thissystemissuitableevenfortankswith

a positive head.

-Avoidcreatingobstacleswhichcouldincreasesuctionlossesdisruptingsmoothuidow.Make

sure that there are no restrictions, sharp turns or tight elbows on the discharge line, since these

increase disturbance.

8.5 ELECTRICAL CONNECTION

Make the electrical connection only after the hydraulic connection has been completed; set up the

motor control system in conformity with the technical standards and regulations in force (EN 60204-

1): in particular a manual electric power switch must be installed with adequate current switching

capacity; devices for overcurrent and overload protection (e.g. fuses, automatic switches, etc.) must

alsobetted,plus,ifnecessary,adevicetopreventaccidentalrestarting.

Check that the main frequency and voltage and the available power are suitable for the motor

installed. All the material used for the electrical connection (cables, cable clamps, switches and

shielding) must have a suitable level of protection for the environment in which it is installed. Be sure

tousecablesofsufcientcross-sectionforthecurrentshownonthemotorplatesoastoprevent

them from overheating.

Before doing anything else, make the motor's earth connection, using the terminal on the motor

andacableofsufcientcross-section.Thecablesmaybeconnectedtotheterminalboardusing

either a delta or star arrangement. Follow the data given on the motor plate for the main voltage, as

showninthediagraming.4.Whenstarting,themotor'scurrentabsorptionincreasesbrieyto5-6

times the nominal value. If the mains supply is unable to sustain this increase in absorption, use a

star-delta starter or other kind of device (e.g. an autotransformer).

C.S.F. Inox S.p.A. will accept no responsibility for damage to property and/or injury to persons caused

by failure to comply with technical standards and regulations in force.

9 NON-PERMITTED USES

Donotusethepumpwithasuctionpressuregreaterthanthespeciedvalue(0.5timesthedischarge

head generated by the pump).

The pump must always be used in an environment appropriate to the level of protection of the motor.

Always check this on the motor plate before installation.

WARNING THE PUMP MAY NOT BE USED IN ENVIRONMENTS WHICH REQUIRE A HIGHER

LEVEL OF PROTECTION OR A HIGHER SPECIFICATION MOTOR OR ELECTRICAL PARTS.

Components complying with the safety standards for the environment in question must be used.
