Overview
This section describes what you have to consider for your own
safety. Read this important section attentively and follow the
instructions!
2.1 Operator notes
2.1.1 Unpacking the pump
In order to avoid transport damage, all of our pumps are
professionally packed when they leave our warehouse.
If, after carefully unpacking and closely reviewing the shipment,
you nevertheless detect damage, please immediately inform the
transporter (railway, post office, freight forwarder, shipping
company). Please file your damage claim with them. The
transport risk is assumed by the customer as soon as the
shipment leaves our warehouse.
2.1.2 Storing the pump
If you do not use the pump straight away, correct storage
conditions are just as important as careful installation and
appropriate maintenance in order to ensure smooth subsequent
operation. The pump should be protected against cold, moisture
and dust, and should also be shielded against mechanical
impacts.
Trained personnel are required for proper installation and
maintenance.
2.2 Safety instructions in the operating manual
Read all safety instructions!
The operating manual contains all the basic information required
for the set-up, operation, and maintenance of the pump. The
installer as well as the technical personnel or operator
responsible for the pump must therefore read this operating
manual before installing and starting the pump. The operating
manual must always be available at the site where the pump/
system is used.
The general safety instructions presented in this section as well
as the specific safety instructions in later sections must be
followed.

2.11 Cleaning
To ensure the quality of sensitive liquids, pumps must be cleaned
immediately after each use. Only this will remove adhesions and
sedimentary deposition and avoid the contamination of products.
To reach the best possible cleaning result, Hilge pumps are
optimised with regard to gaps and dead spaces. They are
designed in accordance with DIN EN 13951, and they are
resistant to the detergents mentioned below. The cleaning
happens inside the plant, without the need for disassembly or
removal of parts.
Generally, distinction is made between CIP and SIP. The
procedures must be based on state-of-the-art technology and
guidelines of the EC. In every case the user must make sure that
the cleaning and/or sterilisation processes used as well as the
operating temperature and operating steps meet the targets set
and are used for that purpose.
WARNING!
Tripping hazard from electric power cable!
▲Death, serious bodily injury.
►Route the electric power cable in such a way
that no one can trip over it (in case of porta-
ble pumps).
DANGER!

Product description
Hygienic design
Because of the consistent hygienic design and the use of
materials that are free of both pores and inclusions, the pump is
highly suitable for use in:
– pharmaceutical industry
– medical technology
– processes in bioengineering
Special areas of application can be found in the delivery of ultra-
pure water and water for injection as well as in systems for the
production of FDA-approved parenteral and infusion solutions.
3.3 Proper usage
3.3.1 Pumped liquids
Only pure or slightly contaminated liquids may be pumped. These
liquids may not chemically or physically attack the pump
materials or reduce their strength. If liquids with a viscosity
greater than that of water are to be pumped, make sure that the
motor will not be overloaded. The pump may not be operated
beyond the maximum permissible values. Even short periods of
pressure overload (e.g. as a result of a pressure surge) should be
avoided.
3.3.2 Minimum flow rate Qmin
Do not operate the pump below the minimum flow rate of
Qmin = 10-15% Qopt.
3.3.3 Connections and pipelines
The nominal diameters of the system pipelines should be equal to
or greater than the nominal diameters of the pump, i.e. DNE
(suction side) and DNA (pressure side), and the elements that are
to be connected to the pump must conform exactly to the design
standard/specification of the mating connector piece installed on
the pump. The suction line must be absolutely leakproof and if
possible laid out in such a way that no air pockets can form. Avoid
tight elbows and do not install valves immediately upstream of the
pump. On the suction side, provide a straight pipe section with a
minimum length of five times the pipe diameter. The suction head
of the system may not exceed the suction head guaranteed by
the pump.
3.3.4 Motor operation
Do not start and stop the motor more than 15 times per hour.
3.3.5 Design
All information and descriptions in this operating manual
concerning the use and operation of the pumps are based

4 Mounting, installation and connection
Overview
This section describes how to mount, install and connect the
pump. You get to know what to consider when you connect the
pump to the electric mains supply and how to improve the flow in
order to avoid dry running of the shaft seals.
4.1 Inspection before pump installation
4.1.1 How to check free running of the impeller
1. Remove motor shroud (if applicable).
2. Remove fan cover of motor.
3. Consider direction of rotation (arrow).
4. Rotate shaft slowly by hand via the fan.
The shaft must rotate easily. If the impeller rubs against the
pump housing, it has been damaged (for example during
transport).
If the impeller rubs against the housing, contact HILGE Ser-
vice.
If the impeller runs freely:
5. Re-fit fan cover of the motor.
6. Re-fit motor shroud (if applicable).

Align the pump in this way
1. Use an engineer’s spirit level laid across the machined surface
of the discharge port to align the pump.
2. After aligning the pump, tighten the mounting bolts uniformly in
a crosswise manner.
4.3 Installation in the pipeline
Fig. 5: Installation in the pipeline
Above: gravity feed mode | below: suction operation mode | P -
pump | M - motor
4.3.1 Operation of the mechanical seal
Mechanical seals require a lubricating film in the sealing gap
which prevents contact between the two sliding surfaces.
Generally, this lubricating film consists of the pumped liquid or an
externally supplied flushing or barrier liquid.
Due to the frictional heat between the sliding surfaces, the
lubricating film will evaporate to the atmosphere. If the pumped
liquid is water, watery liquids or volatile liquids, the leakage will
thus not be visible. For perfect operation, the amount of leakage
is usually only a few ml/h, but - depending on other
circumstances - it may rise.
Particularly during the run-in period, and independent of size,
shape or design, mechanical shaft seals may discharge a low
leakage. In some cases it may be necessary to tolerate a small,
visible leakage or to counteract this with appropriate measures.
TM05 7184 2913
WARNING!
Mechanical overload!
▲Death, bodily injury, damage to property.
►Do not use the pump or its connecting
sleeves to support the pipeline (EN 809
5.2.1.2.3 and EN ISO 14847).
►In addition to the general rules of machine-
building and system construction, also follow
the instructions provided by the manufacturer
of the connecting elements used (e.g.
flanges) when installing the pump in the pipe-
line or system. These specifications will con-
tain data on torques, maximum permissible
angular offset and tools/auxiliary materials to
be used.
►After connecting the pipes, check the align-
ment of the coupling.
►It is absolutely necessary to avoid twisting
the pump.
CAUTION!
Mechanical overload due to foreign objects!
▲Damage to property.
►The suction and discharge ports are sealed
with sheets of plastic, and the flushing and
drain lines with plastic caps. These must be
removed before the pump is installed in the
system.
CAUTION!
Dry running!
▲Damage to property.
►The suction line must be absolutely leakproof
and laid in such a way that no air pockets can
form.
►Avoid tight elbows and valves immediately
upstream of the pump. They interfere with the
incoming flow to the pump and thus with the
NPSH of the system.
►The nominal pipeline diameters of the system
should be equal to or greater than the con-
nectors of the pump.
►A foot valve should be used in suction opera-
tion mode.
►To prevent air pockets from forming, the suc-
tion line must be laid so that it rises to the
pump, whereas a gravity feed line must be
laid with a slight downward gradient to the
pump.
►If local conditions do not allow the suction
line to ascend continuously, install a venting
device at the highest point of the line.
►An isolating valve should be installed in the
suction line near the pump. This valve must
be completely open during operation and
may never be used as a control valve.
►An isolating valve should be installed in the
discharge line, near the pump, to control the
flow rate.

Dry running
To achieve a proper sealing, mechanical seals require a
lubricating film between the sliding surfaces.
Dry running occurs if the lubricant film between the sliding
surfaces is missing or wears away. The frictional heat generated
by direct contact of the sliding surfaces will damage the
mechanical seal. Depending on the material combination, this will
happen within a few seconds. (see fig. 6).

4.3.2 Space requirements
Pay attention to motor power. Maintain the minimum distances.
Fig. 7: Minimum distances
4.3.3 Elimination of noise and vibrations
In order to achieve optimum operation and minimum noise and
vibration, consider vibration dampening of the pump. Generally,
always consider this for pumps with motors above 11 kW. Smaller
motors, however, may also cause undesirable noise and
vibration.
Noise and vibration are generated by the rotations in the motor
and pump and by the flow in the pipework and fittings. The effect
on the environment is subjective and depends on correct
installation and the state of the remaining system.
Foundation
Vibration dampening is best achieved by installing the pumps on
a plane and rigid concrete foundation.
Fig. 8: Example of a pump foundation
– A - expansion joints
– B - foundation
– C - vibration dampers.
As a guideline, the weight of the concrete foundation should be
1.5 times the pump weight.
Vibration dampers
To prevent vibrations from being transmitted to the building, we
recommend that you isolate the pump foundation from buildings
by means of vibration dampers.
The selection of the correct vibration dampers requires the
following data:
• Forces that will be transmitted through the vibration dampers
• Motor speed, taking speed control into account as needed
• Required dampening in % (suggested value is 70 %).
The right damper varies from installation to installation, and the
wrong damper may increase the vibration level. Vibration
dampers should therefore be sized by the supplier.
Expansion joints
If the pump is installed on a pedestal with vibration dampers,
expansion joints must always be fitted on the pipeline
connections. This is important to prevent the pump from
"hanging" in the connections.
Install expansion joints in order to
• absorb expansion/contractions in the pipework caused by vari-
able liquid temperatures
• reduce mechanical strains that occur in connection with pres-
sure surges in the plant
• isolate mechanical structure-borne noise in the pipework (only
rubber bellows expansion joints).
Note: Do not install expansion joints to compensate for
inaccuracies in the pipework such as centre displacement of
flanges.
Fit expansion joints at a distance of at least 1 to 1½ times the
nominal flange diameter away from the pump on the suction as
well as on the discharge side.
This will prevent the development of turbulence in the expansion
joints, resulting in better suction conditions and a minimum
pressure loss on the discharge side.
We always recommend expansion joints with limiting rods for
flanges larger than DN 100.
The pipes should be anchored so that they do not stress the
expansion joints and the pump. Follow the supplier’s instructions
and pass them on to advisers or pipe installers.
TM05 6444 4912
WARNING!
Overheating!
▲Damage to property.
►Ensure sufficient ventilation.
►Make sure not to reabsorb warm cooling air.
Consider other heat sources in the area.

4.4 Connections for flushing system
4.4.1 Flushing liquid
Flushing liquid requirements
The function of the flushing liquid is to lubricate and cool the
mechanical seal on the product side as well as the lip seal on the
atmospheric side.
The flushing liquid must meet the following requirements:
• good flowability
• flushing liquid not contaminated
• no solids
• no dissolved constituents
• sufficient thermal conductivity
• no chemical or mechanical attack of the pump materials, seal-
ing materials and elastomers.
• flushing liquid not contaminating the pumped liquid
• viscosity < 5 mPas
• water hardness < 5 °dH.
The above requirements are to a high degree met by
demineralised water.
Permissible supply pressures and temperatures
The supply of the mechanical seal with flushing liquid must be
non-pressurised. The pressure must not exceed 0.2 bar.
In case of flush cycle installation, protect the flushing liquid
connection with a pressure regulator or similar.
If the flushing system is a closed flushing loop with flushing liquid
tank, observe the filling level either visually or by means of a
filling level probe.
Make sure that a pressure build-up within the flushing loop is
impossible. Keep the flushing liquid tank open to the atmosphere.
In case of critical pumped liquids, change the flushing liquid
regularly.
The temperature of the flushing liquid must not exceed 60 °C at
the outlet from the pump flushing chamber.
The temperature rise within the pump flushing chamber is
normally less than 5 K.
4.4.2 Quench design
HILGE pumps with a quench are equipped with a lip seal.
The unpressurised flushing liquid flows between the mechanical
seal and this lip seal.
Connect the lines as shown in fig. 9.
Fig. 9: Connection for flushing system
A - Outlet
B - Inlet
Connect the flushing system in this way:
1. Connect outlet line A (see fig. 9).
2. Connect inlet line B.
3. Check tightness of connection.
4.5 Electrical connections
CAUTION!
Vibration!
▲Damage to property.
►Make sure that pipes and pumps are fixed
firmly to foundation or building. Insufficiently
rigid structures may cause oscillations if
operating conditions are changed, e.g. by
fluctuations in hydraulic and/or motor forces.
P.122.0000.0025R1
CAUTION!
Dry running!
▲Damage of property.
►Connect the lines of the flushing system so as
to guarantee a liquid supply.
►Ensure that the pressure of the flushing liquid
never exceeds 0.2 bar.
►Always keep the filling level of the flushing
liquid tank between the upper and lower
marks.
DANGER!
Electric shock!
▲Death, serious bodily injury.
►The electrical connections must be made by
a qualified electrician.

4.5.3 Frequency converter operation
All three-phase motors can be connected to a frequency
converter. Frequency converter operation can subject the motor
insulation to enhanced strain. This may lead to more motor noise
than normal as a result of eddy currents caused by transients.
Large motors operated via a frequency converter are subject to
bearing currents. For motors size 37 kW and higher in pumps that
are operated by an external frequency converter, HILGE recom-
mends the use of insulated motor bearings to avoid increased
wear of motor bearings by bearing currents.
Please consider the following operating conditions if the pump is
operated using a frequency converter:
Please follow the manufacturer's instructions when installing and
operating a frequency converter.
4.5.4 Checking the direction of rotation after
connection
Check the direction of rotation in this way:
1. After electrical connection, mount all safety equipment again.
2. Check tightness of hydraulic connection.
3. Open isolating valves.
4. Fill pump (system).
5. Observe the direction-of-rotation arrow.
6. Switch on motor for a short time (1-2 seconds).
7. Compare directions (motor/arrow).
8. Correct connection if necessary.
Operation with frequency converter
See the manufacturer’s documentation.
DANGER!
Motors with frequency converters (Tronic) - risk
of electric shock from live parts!
▲Death and serious bodily injury.
►Even if the power supply is switched off,
touching electrical components can lead to
electric shock.
►Before touching electrical components, dis-
connect the power supply and wait at least
four minutes.
WARNING!
Capacity overload!
▲Death, serious bodily injury, damage to prop-
erty.
►Check that the operating voltage corresponds
to the voltage stated on the nameplate of the
motor!

Check the application conditions of the pump in this way:
1. Compare the data of the following documents with the pro-
vided application conditions of the pump:
– purchasing documents (confirmation of the order)
– nameplate
– operating manual.
2. Make sure that the pump will operate under the specified con-
ditions only. Theses conditions apply to (e.g.) pressure, tem-
perature, and pumped liquid.
5.1.2 Starting up the pump
Start-up the pump in this way:
1. Check tightness of connection.
2. Make sure that all safety equipment is installed.
3. Make sure that all electrical connections are correct.

If the discharge head does not rise after the pump has been
turned on:
1. Switch off the pump.
2. Vent the pump (system) again.
3. Repeat steps 7. to 10.
5.1.3 Functional check of the mechanical seal
Check the function of the mechanical seal in this way:
1. Watch the pump and check the mechanical seal for fault-free
functioning (leak test).
2. An intact mechanical seal works virtually without leakage.
If the pumped liquid or flushing liquid leaks:
1. Switch off the pump.
2. Replace the mechanical seal.
Observe safety instructions in chapter 6.1 on page 18.
5.2 Shutting down the pump
A pressure surge is an abrupt pressure increase in the system.
This pressure increase can, for example, be caused by a quick
blocking of the flow in the discharge pipe. In the event of a pres-
sure surge the maximum permissible pump pressure is temporar-
ily exceeded considerably.
Shut down the pump in this way:
1. Switch off the pump.
2. Close the isolating valve on the discharge side.
3. Close the isolating valve on the suction side.
4. Switch off the flushing system (if applicable).
