1.0 Safety

This operating manual gives basic instructions

which are to be observed during installation,

operation and maintenance of the pump. It is

therefore imperative that this manual is read by

the responsible personnel/operator prior toassembly and commissioning. It is always to be

kept available at the installation site.

It is not only the general safety instructions

contained under this chapter Safety to be

observed, but also the specific information

provided under the other chapters.

1.1 Identification of safety

prescriptions in the operation

instructionsSafety prescriptions given in these operation

instructions, non compliance with which would

affect safety are identified by the following symbol

Danger symbol as per DIN 4844-W9

(ISO 3864 - B.3.1)

or in case of warning of electrical voltage with:

Danger symbol as per DIN 4844 W-8

(ISO 3864 - B.3.6)

The word

ATTENTION

identifies the safety regulations whose non

compliance may cause danger for the machine

and its function. It is imperative that signs affixed

to the machine, e.g.

• arrow indicating the direction of rotation

• symbols indicating fluid connections

• type plate

must be observed and kept legible.

1.2 Qualification and training of

personnel

The personnel responsible for operation,

maintenance, inspection and assembly must be

adequately qualified. Scope of responsibility and

supervision of the personnel must be exactlydefined by the plant operator. If the staff does not

have the necessary knowledge, they must be

trained and instructed which may be performed by

the machine manufacturer or supplier on behalf of

the plant operator. Moreover, the plant operator is

to make sure that the contents of the operation

instructions are fully understood.

1.3 Hazards in case of non

compliance with the safetyinstructions

Non compliance with the safety instructions may

produce a risk to the personnel as well as to the

environment and the machine and results in a loss

of any right to claim damages.

For example non compliance may involve the

following hazards:

• failure of important functions of the

machine/plant

•

failure of specified procedures of maintenanceand repair

• exposure of people to electrical, mechanical

and chemical hazards

• endangering the environment owing to

hazardous substances being released

1.4 Compliance with regulations

pertaining to safety at work

When operating the pump the safety instructions

contained in this manual, the relevant national

accident prevention regulations and any other

service and safety instructions issued by the plant

operator are to be observed.


3/32



1.5 Safety instructions relevant for

operation

• If hot or cold machine components involve

hazards, they must be guarded by the user

against accidental contact.

•

Guards for moving parts (e.g. couplings) mustnot be removed from the machine while in

operation.

• Any leakage of hazardous (e.g. explosive,

toxic, hot) fluids (e.g. from the shaft seal) must

be drained away so as to prevent any risk

occurring to persons or the environment.

Statutory regulations are to be complied with.

• Hazards resulting from electricity are to be

precluded by the user (see for example the

VDE-specifications and the bye-laws of thelocal power supply utilities).

1.6 Safety instructions relevant for

maintenance, inspection and

assembly work

It shall be the plant operator’s responsibility to

ensure that all maintenance, inspection and

assembly work is performed by authorised

personnel who have adequately familiarised

themselves with the subject matter by studyingthis manual in detail.

Any work on the machine shall only be performed

when it is at a standstill. It is imperative that the

procedure for shutting down the machine

described in this manual is to be followed.

Pumps and pump units which convey hazardous

media must be decontaminated.

On completion of work all safety and protective

facilities must be re-installed and made operative

again. Prior to re-starting the machine, the

instructions listed under „first commissioning“ are

to be observed.

1.7 Safety instructions for the use in

areas with explosion hazard

In this paragraph information are given for an

operation in areas with explosion hazard.

1.7.1 Arrangement of the units

If the pump is completed with other mechanical or

electrical components to one unit, the complete

unit may be considered only as device category

according to the directive 94/9/EC which is fulfilled

by all used components.

Note:

This instruction gets special meaning when using

pumps which are corresponding to a device

category according to the directive 94/9/EC,

however, are driven by a motor which does not

meet these criteria. Then it might be that the pump

has been provided with the EX-sign but the unit

must not be used in areas with explosion hazard

due to the non EX-admitted motor. So theoperator has always to pay attention to the

conformity with the directive 94/9/EC of all used

components of the pump unit.

1.7.2 Execution of coupling guards

for shaft couplings

Coupling guards which shall be used in areas with

explosion hazard have to fulfill the following

criteria:

•

non- sparking material e.g. brass has to beused or

• steel plate constructions have to be used,

which are executed in a way that with faults to

be foreseen (e.g. deformation by stepping on

the coupling guard) a mechanical contact of

the rotating parts is impossible.


4/32



1.7.3 Surveillance of technical

parameters

When using pumps in areas with explosion hazard

the operator has to check regularly the following

parameters:

•

leakage of the shaft seals• if necessary bearing temperatures

• liquid level in the pump during commissioning

• for pumps with magnetic coupling the

temperature of the electrically conductive

isolation shroud has to be controlled

The operator has to ensure that the pump, with

abnormal conditions, will be taken out of operation

/not be taken again in operation at short notice.

The advises regarding operation and maintenance

given in this operation manual have to be kept to.Particular informations concerning the surface

temperatures of the pump are given in chapter 9

of this operation manual.

1.7.4 Avoidance of sparks caused by

exterior impact effect

The operator has to ensure that with an operation

of the machine in areas with explosion hazard no

exterior impact effect to the machine casing may

create sparks.

1.8 Unauthorised alterations and

production of spare parts

Any unauthorized modification of the machine will

result in an exemption of Sterling SIHI from any

liability. In such cases the operator of the machine

takes over the responsibility for the safe operation.

Using spare parts and accessories authorised by

the manufacturer is in the interest of safety. Use of

other parts may exempt the manufacturer from

any liability.

1.9 Unauthorised mode of operation

The reliability of the machine delivered will only be

guaranteed if it is used in the manner intended

and in accordance with the instructions of this

manual. The specified limit values must not be

exceeded under any circumstances.

1.10 Warranty / guarantee

2.0 Application

The pump is to be applied only for the operating

conditions stated by the orderer and confirmed by

the supplier. Guarantee is assumed within the

scope of the Sterling SIHI conditions of sale.

This pump is able to handle liquids which do notcontain solid particles regularly and which do not

contain ferromagnetic particles.

If a permanent pollution of the liquid is to be

expected, the partial flow has to be led via a free

flow filter (designation of type see table under 2.5).

The pumping liquid must not tend to

evapourisation, polymerisation, crystallisation or

hardening under the given pressure and

temperature conditions.

2.1 Warning of misuse

• You may use the pump only for the application

stated in the acknowledgement of order as

otherwise hazards for people and environment

may occur.

• Do not exceed the density and viscosity stated

in the acknowledgement of order. Otherwise

there is the danger of damage to the magnetic

coupling.

• The torque of the motor must not be higher

than the nominal torque of the magnetic

coupling. Otherwise there is the danger of

destruction of the coupling.

• When hot liquids are pumped, the surface of

the pump heats up in a way, that it can not be

touched without the danger of injury.

• The pump must not be exposed to temperature

shocks.

2.2 Accessories

Measuring devices or other accessories may only

be mounted after approval of Sterling SIHI. If this

approval is not given, warranty claims will not be

accepted.

2.3 Description

The design of the supplied pump is specified in

the product identification table on the next page

(see chapter 2.5).

2.4 Construction and mode of operation

Pumps of this product line are volute casing

pumps acc. to EN 22858 (chemical-standard-

pump). The sealing against atmosphere is made

by an isolation shroud. The driving torque of the

motor is transmitted to the pump shaft by a

magnetic coupling.

The pump shaft with the impeller and the interior

magnet is run in two sleeve bearings lubricated by

the medium.The outer part of the magnetic coupling (the

magnetic bell) is placed on a clutch shaft, which is

run in two ball bearings in the bearing bracket. In

the gap between magnetic bell and inner magnet

lies the isolation shroud.

2.5 Product identification

The design of the pump is described by the pump

type, which is described in the following table.

Planning of the installation Page 1 of 2 Chapter 3

03DE2.DOC Subject to technical alterations Copyright Sterling SIHI GmbH

3.0 Planning of the installation

3.1 Piping system

ATTENTION

• If the pump is mounted vertically, suction lift

operation is not permitted as the ventilation of

the isolation shroud then cannot be ensured.

• Pay attention to the arrows at the pump

branches indicating the flow direction.

• The nominal widths of the pipelines must not

be smaller than the nominal widths of the

corresponding pump branches.

• All pipelines must be cleaned prior toinstallation of the pump.

• The pipelines must be supported in order to

avoid distortions of the pump components

(danger of breaking of the pump

components).

• Avoid abrupt transitions of cross section and

changes of direction.

• Unequal nominal widths are to be

compensated by excentric transition pieces.

The extension of the cross section has to be

made downward in order to avoid the

formation of air pockets in the pipeline.

• In front of the suction branch of the pump a

flow normalizer has to be arranged; it shall

have the diameter of the nominal width of the

suction branch and the length of 15 times the

diameter of the suction branch. This secures

favourable inflow conditions.

• The flow velocity in the suction line or inflow

line, respectively, must not exceed 2 m/s.

• The pipelines are to be laid in such a way that

thermal expansion in the pipe system does

not have any effect on the pump branches.

3.1.1 Installation plan

3.1.2 Suction line or inflow line, resp.

The suction line must ascend to the pump. The

inflow line must slightly descend to the pump.

Gate valves in the suction line or inflow line must

be kept completely open during start and

operation of the pump.

Gaspendelleitung

Suction head operation Suction lift operation

If dirt particles are to be expected either from the

pipework or from the pumping medium, a filter

must be installed in the pipeline. The free section

of the filter must have at least the triple section

surface of the nominal width of the pump. Mesh

size = 0,1 mm.

3.1.3 Discharge line

In order to adjust the pumping data a gate valve isto be installed behind the pump. If non-return

elements are applied they shall have the property

of closing smoothly. Prevent pressure surges.

3.1.4 Installation of an orifice

- Q-max-orifice

In order to avoid the exceeding of the admissible

output a Q-max orifice should be fitted into the

discharge line (see installation plan). This secures

sufficient lubrication of the sleeve bearings and

the safe dissipation of the heat due to energy

losses of the magnetic coupling.


8/32

Planning of the installation Page 2 of 2 Chapter 3

03DE2.DOC Subject to technical alterations Copyright Sterling SIHI GmbH

- Q-min-orifice or overflow valve, resp.

In order to avoid that the output goes below the

required minimum, an overflow valve or a Q-min-

orifice should be fitted (see installation plan). This

secures sufficient cooling of the magnetic

coupling.

3.1.5 Pressure control

For the proper pressure control two measuring

points are to be provided at the pipelines, one

before and one behind the pump. (see installation

plan).

3.2 Electrical connections

For the drive motor a mains connection is

required which complies with relevant regulationsand laws. The start up of centrifugal pumps with

star-delta-switch normally leads to a higher power

consumption during the switch to delta than the

direct start up in delta connection. The

accelerating torque during the switch from star to

delta connection is very high, so that a

desynchronisation of the magnetic coupling might

happen. Therefore a direct start up is

advantageous, especially with pumps with big

moments of inertia. Normally this has to beapproved by the local power supplier. If the direct

switch on in delta connection is not allowed, a soft

starter (see point 3.3.4) might be necessary.

3.3 Accessories

For this pump the following accessories are

available:

• Load detector for the control of the motor

power absorption

• Temperature probe PT 100 for the control of

the temperature of the isolation shroud

• Level transmitter for the protection against dry

operation

• Soft starter

3.3.1 Load detector

The load detector measures the power absorption

of the drive motor. If the absorption becomes too

high, e.g. by blocking of the rotor or decreases by

desynchronization of the magnetic coupling, the

motor is switched off automatically. Thus a

damage to the magnetic coupling or to the pump

is prevented.

3.3.2 PT 100

The PT 100 is a resistance thermometer for the

control of the temperature of the isolation shroud.It is screwed on the pump by a threaded

connection. The switch-off temperature is to be

adjusted by 10 °C higher than the operating

temperature. In case of variable temperatures the

control values should be inquired at Sterling SIHI.

3.3.3 Level transmitter

In order to ensure that the pump only can be run

with a sufficient liquid level, a level transmitter

should be installed. It must guarantee that asufficient liquid quantity will always be available.

Therefore it has to installed in the pipework above

the pump.

3.3.4 Soft starter

When selecting the magnetic coupling, the

decision to apply a soft starter may result in the

fact that a coupling with smaller nominal torque,

i.e. a cheaper one, can be applied. The use of a

smaller coupling also results in lower eddy currentlosses. Therefore the power consumption of the

pump is lower and the efficiency increases.

6.8 Putting into operation

For putting into operation proceed as follows:

1. Open fully the shut-off element at suction side.

2. Open only slightly the regulating element at

discharge side.

3. Switch on the motor.

4. Check the pressure gauges at the pressure

measuring points.

If the pumping pressure does not constantly

rise with increasing speed, the motor is to be

switched off again and the pump must carefully

be vented once more.

5. After reaching the operation speed regulate the

operating point of the pump by actuating theregulating elements in the discharge line.

The operation against closed regulation elements

in the discharge line is admissible only if the min.

output via a bypass line is guaranteed.

By means of safety measures at the plant (e.g.

overflow valve) it must be ensured that the

admissible casing pressure of the pump is not

exceeded because of malfunction during

operation.The alignment of the coupling should be repeated

at operational temperature. If necessary the pump

or the drive motor, respectively, is to be re-aligned.

6.9 Switching frequency

The pump may be switched on and off max. 8

times per hour.

Before switching on the pump again it is important

that the pump rotor has come to a stop because

otherwise the magnetic coupling coulddesynchronize.

6.10 Special instructions

During operation the following points are to be

observed:

• Control the speed and the delivery head.

• Ensure that the pump runs without vibration.

• Control the liquid level in the suction or inflow

tank, respectively.

•

Control the temperature of the ball bearings inthe bearing bracket.

(max. permissible temperature: 100°C)

• If oil lubricated ball bearings are installed, the

oil level has to be controlled.

ATTENTION

If the magnetic coupling should desynchronize

(motor and outer magnet are rotating, but not the

pump), the motor must be switched off, the cause

of the desynchronization must be eliminated and

then the unit can be started again.

A long time of operation during desynchronization

causes damage to the magnetic coupling!

6.11 Putting out of operation

For putting out of operation proceed as follows:1. Switch off the motor.

2. Close the regulating element at discharge side.

3. Close the shut-off element at suction side.

If there is the risk of freezing, drain the pump and

preserve it.

ATTENTION

Even after emptying residual liquid remains inside

the pump. If the pump has to be dismounted, itshould be washed, to make sure that the personel

will not be endangered by getting in contact with

the pumping medium.

Maintenance, disassembly, assembly Page 1 of 5 Chapter 7


7.0 Maintenance, disassembly,

assembly

7.1 Preconditions

The pump or the pump unit, respectively, has

been put out of operation acc. to the instructionsof chapter 6.

7.2 Target group



Work at electrical connections must be carried out

by authorized skilled staff only.

7.3 Safety measures

• Pumps with magnetic couplings are equipped

with strong permanent magnets. Data carriers

and electronic components must not be

placed near dismounted components.

The effect of magnetic fields on cardiac

pacemakers is not researched sufficiently.

For reasons of safety, concerned persons are

to be relieved from mounting work on pumpswith magnetic couplings.

The reach of magnetic fields is only a few

decimetres; when installed the magnets are

screened off.

• The parts of magnetic couplings must be

placed at sufficient distance from each other.

There exists danger of injury by parts

attracting each other.

• The disassembly and assembly requires a

clean and antimagnetic workshop place.• Drain the pump after disassembly out of the

plant. After draining residues of liquid will

remain in the pump. As these residues

become free only during disassembly,

preventive measures must be taken before

disassembly.

7.4 Maintenance and inspection

The pump requires only little maintenance.

However, after 8.000 service hours, at least after 2years, the inner sleeve bearings are to be

checked.

But the ball bearings in the bearing bracket should

be checked in regular intervals.

7.4.1 Grease lubricated ball bearings

The ball bearings are sealed and filled with

lubricant.

After approx. 10000 hours of operation, at the

latest after two years, the bearings are to bedismounted, checked and to be exchanged if

necessary.

In case of especially unfavourable conditions of

operation (humidity, dust and/or high ambient

temperatures) the maintenance intervals must be

considerably shorter.

7.4.1 Oil lubricated ball bearings

The pumps are delivered without an oil-filling.

The oil-level is controlled by a constant level oiler.Therefore the pump has to be installed horizontal.

In every case, also at the first filling, the oil has to

be filled in the flapped back oil tank. After

reflapping the oil tank the oil flows into the bearing

bracket. This procedure has to be repeated until

the oil does not flow out of the oil tank anymore.

Then the correct oil level is reached.

With new bearings, the oil shall be renewed after

about 200 h of operation. After this renewing of

the oil, the oil shall be renewed acc. to the

following table.

light duty medium or heavy duty

very low pollution,

T < 50°C

low pollution,

T > 50°C

renewing of the oil once

a year

renewing of the oil after

half a year

Only high-quality oils according to DIN 51517, CL

46 are to be used (for example Shell Vitrea 46,

Esso Esstic 46).

7.5 Disassembly

7.5.1 Preparation for disassembly

Proceed acc. to the following check list:

1. Switch the power supply of the motor free from

voltage.2. Disconnect the motor.

3. Drain the installation at least within the pump

area, i.e. between the shut-off elements at

suction and at discharge side.

4. If necessary disconnect measuring probes and

control instruments and dismount them.

5. Dismount the coupling. Loosen the screws of

the pump feet from the base plate.

7.5.2 Replacement partsWhen ordering spare parts, the item number from

effect gets lost. This is not valid for the pumps with

mag drive system 3. In this case the lock washer

might have to be renewed.


17/32



7.7.2 Assembly of the pump

Carry out the following steps:

1. Assemble the cover 16.00 / 16.01 with the

strainer insert 75.80 and the bearing carrier

38.10 by using the screws 90.11.During the assembly of the bearing carrier 38.10to the covers 16.00 and 16.01, the correct positionof the bores for the partial flow has to beobserved.The position of the bearing carrier 38.10 controlsthe partial flow and the pressure-level in the rear wear ring of the impeller. By turning the bearingcarrier on 90° two different positions and thereforetwo different values of partial flow can be adjusted.

At small differential heads and low axial thrustposition 1 will be chosen to ensure a sufficientcooling and lubrication flow. At high differentialheads, high axial thrust or when NPSH-problemsoccur, position 2 will be chosen.

position 1:The bearing carrier 38.10 has to be assembled ina way, that the two big bores for the partial flow

(∅ 9mm) are placed on the horizontal axis, andare congruent to the bores in the covers 16.00 and16.01. Therefore the partial flow is led to thebackside of the impeller via these two 9mm-bores.

position 2:The bearing carrier 38.10 has to be assembled ina way, that the two big bores for the partial flow

(∅ 9mm) are placed on the vertical axis. Then the

small bore for the partial flow (∅6mm) is placed

on the horizontal axis congruent to one of the9mm-bores in the covers 16.00 and 16.01.Therefore the partial flow is led to the backside of the impeller via this 6mm-bore.

The following table shows, which positions have to

be chosen for the different pump sizes.

Technical Data, Annex page 1 of 2 Chapter 9 and 10


9.0 Technical Data

Flange connections and hydraulic data acc. to DIN EN 22858 / ISO 2858 (chemical standard pump)

temperature of the pumping medium: -40°C up to 180°Cwhen the temperature of the pumping medium is lower than 0°C, thestandard pump with the closed bearing bracket has to be used. Thebearing bracket has to be sealed against the flange for the can (81.71)

by using Soft PTFE-Cord-sealing material.By doing so, the entrance of air humidity in the area of the outer magnet and isolation shroud is prevented. Therefore the freezing of the condensated air humidity during the times the pump is not runningwill not happen in such an amount, that the outer magnets freezes tothe isolation shroud.Pumps with an open bearing bracket can be used for mediumtemperatures up to max. 300°C. (designation of this type: see table inchapter 2)

Surface temperature: The surface temperature of the pump will be very close to thetemperature of the pumping medium. Especially in areas with definedtemperature class regarding the safety against explosions, measures

have to be taken to assure, that the surface temperature of the pumpdoes not exceed the permitted temperature.

kinematic viscosity: To ensure safe operation of the pump, the kinematic viscosity of thepumping medium has to at least 0,3 mm²/s and has to be lower than300 mm²/s. In any case, the viscosity has to be kept in mind during theselection of the drive and of the magnetic coupling. In some casesalso lower viscosities than 0,3 mm²/s can be handled. Please askSterling SIHI for further information.

Casing pressure: PN 16 or PN 25(designation of the different types see table in chapter 2) Dependingon the temperature of the pumping medium, the admissible casingpressure may decrease. This is shown in the following diagramms.
