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.

1.5 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.

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.

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.
-
8/16/2019 Manual Bomba Sihi
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.

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
The work described in this chapter must be
carried out by trained skilled staff only.
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).

7.7.2 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.

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.
