2 Safety
The manufacturer accepts no liability for damage caused
by disre garding any of the documentation.
2.1 Intended use
• Only use the pump with suitable media (→ resistance lists).
• Do not use pump for combustible or explosive fluids.
• Adhere to the operating limits and size-dependent minimum flow rates.
• Avoid cavitation:
– Open the suction-side fitting and do not use it to regu-
late the flow.
– Do not open the pressure-side fitting beyond the
agreed operating point.
• Avoid overheating:
– Do not operate the pump while the pressure-side fitting
is closed.
– Note mi nimum flow (→ Data sheet).
• Avoid damage to the motor:
– Do not open the pressure-side fitting beyond the
agreed operating point.
– Note the maximum permissible number of times the
motor can be switched on per hour (→ manufacturer's
specifications).
• Consult with the manufacturer regarding any other use of
the device.
• If pumps are delivered without motors, then final assembly
as a pump assembly must take place in a ccordance with
the provisions of the Machinery Directive 2006/42/EC.
• Use the pump only as part of a large system/tool.
Prevention of obvious misuse (examples)
• Observe pump limits of use regarding temperature, pressure, flow and speed (→ data sheet).
• The power consumption of the pump increases as the spe
cific gravity of the pumped fluid increases. Adher
permissible specific gravity in order to elimin
sibility that the pump, coupling and motor bec
loaded (→ data sheet).
A lower specific gravity is permis
systems accordingly.
• When conveying fluids containing solids, observe the limit
values for proportions of solid particles and particle size
(→ Data sheet, technical description).
• When using auxiliary plant systems:
– Ensure c ompatibility of the operating medium with the
product medium.
– Ensure constant supply of the relevant operating
medium.
• Pumps used wi
used for foo
ing wate
th water as the pumped liquid must not be

removal and installation of the pump and the motor
– Pump not exposed to external vibration (damage to
bearings)
– No corrosive exposure
– Frost protection
300 106 BA-2018.08.22 EN ETL 11
Material damage due to excessive forces and torques on
the pump.
Ensure pipe connection without stress.
1. Plan pipes safely:
– No pulling or thrusting forces
– No bending moments
– Adjust for changes in length due to temperature
changes (compen sators, expansion shanks)
2. Support pipes in front of the pump.
3. Ensure the pipe supports have permanent l ow-friction
properties and do not seize up due to corrosion.
NOTE
Setup and connection
5.3.2 Specifying nominal width s
Keep the flow resistance in the pipes as low as possible.
1. Make sure the suction extension is not smaller than the
nominal width of the suction branc h.
2. Make sure the nominal pressure line width is not smaller
than the nomi nal discharge flange wi dth.
– Ensure the flow velocity is less than 3 m/s.
5.3.3 Designing pipelines
Plan pipes safely:
– No pulling or thrusting forces
– No bending moments
– Adjust for changes in le ng th due to temperature
changes (compensators, expansi on shanks)
5.3.4 Optimizing changes of cross section and
direction
1. Avoid radii of curvature of less than 1.5 times the nominal
pipe diameter.
2. Avoid abrupt changes of cross-section along the piping.
5.3.5 Providing safety and control devices
(recommended)
Avoid reverse running
1. Install a non-return valve between the discharge flange and
stop valve, to ensure that the medium does not flow back
after the pump is switched off.
2. In order to enable venting, include vent connection
between discharge flanges and non-return valve.
Make provisions for isolating and shutting off the pipes
For maintenance and repair work.
Provide shut-off devices in the pressure pipe.
Allow m easurements of the operating conditions
1. Provide a pressure gauge in the pressure line for pressure
measurement.
2. Provide pressure measurement on the pump side.
5.4 Connecting the pipes
NOTE
Material damage due to excessive forces and torqu es on
the pump.
Ensure pipe connection wi thout stress.
5.4.1 Keeping the piping clean
NOTE
Material damage due to impurities in the pump!
Make sure no impurities can enter the pump.
1. Clean all piping parts and fittings prior to assembly.
2. Flush all pipes carefully with neutral medium.
3. Ensure no flange seals protrude inwards.
4. Remove any blin d flanges, plugs, protective foils and/or
protective paint from the flanges.
5.4.2 Installing the pressure pip e
1. Remove the transport and sealing covers from the pump.
2. Fit the pressure line stress-free and sealed
(→ 9.2.2 Flange tightening torques, Pa ge 25).
3. Ensure no seals protrud e inwards.
5.4.3 Inspection for stress-free pipe connections
Piping installed and cooled down
1. Disco nnect the pipe connecting flanges from the pump.
2. Chec k whether the pipes can be moved freely in all directions within the expected range of expansion:
– Nominal width < 150 mm: by h an d
– Nominal width > 150 mm: with a small lever
3. Make sure the flange surfaces are parallel.
4. Reconnect the pipe connecting flanges to the pump.
5. If present, check s upport foot for stress.

5.5 Electrical connection
DANGER
Risk of electrocution!
All electrical work must be carried out only by qualified electricians.
Before all work on the electrical system, disconnect the
motor from the mains and secure against being switched
back on again.
5.5.1 Connecting the motor
Follow the instructions of the motor manufacturer.
1. Connect the motor according to the connection diagram.
2. Make sure no danger arises due to electric power.
3. Install an EMERGENCY STOP switch.

Setup and connection
DANGER
Danger to life from rotating parts.
Use personal protective equipment when carrying out any
work on the pump.
Maintain an adequate distance from rotating parts.
1. Switch on motor for max. 2 seconds and switch it off again
immediately.
2. Check whether the sense of r otation of the motor matches
the direction of rotation on the fan impel ler.
3. If the sense of rotation is different: Change over any two
phases.
5.6 Performing the hydrostatic test
Only necessary if the entire system needs to be tested
under pressure.
NOTE

dance with local regulations.
Take the following measures whenever the pump is shut
down:

Trained servic e technicians are available for fitting and
repair work. Sub mit evidence of conveyed medium on
request (DIN safety data sheet or safety certificate).
7.1 Inspections
The inspection intervals depend on the operational strain
on the pump.
DANGER
Risk of injury due to running p ump!
Do not touch the pump when it is running.
Do not carry out any work on the pump when it is running.
WARNING
Risk of injury and poisoning due to hazardous pumped
liquids!
Use protective equipment for any work on the pump.
1. Chec k at appropriate intervals:
– Adherence to the minimum flow rate
– Normal operating con ditions unch anged
– Filling level of the container
2. Fo r trouble-free operation, always ensure the following :
–Noleaks
–Nocavitation
– Free and clean filters
– No unu sual running noises or vibrations
– No inadmissi ble leaks on the shaft seal
7.2 Servicing
Operating life of antifriction bearings when operated within
the permissible range: >2 years.
Intermittent operation, high temperatures, low viscosities
and aggressive ambient and process conditions reduce the
service life of antifriction bearings.
Plain bearings are subject to natural wear and tear which
is heavily dependent on the respective operating conditions. It is therefore not possible to make general statements about the operating life.
DANGER
Risk of injury due to running p ump!
Do not touch the pump when it is running.
Do not carry out any work on the pump when it is running.
Before all in s tallation and maintenance work, disconnect
the motor from the mains and secure it again st being
switched back on again.
DANGER
Risk of electrocution!
All electrical work must be carried out only by qualified electricians.
Before all work on the electrical system, disconnect the
motor from the mains and secure against being switched
back on again.
WARNING
Risk of injury and poisoning due to hazardous or hot fluid!
Use protective equipment for any work on the pump.
Allow the pump to cool down completely before commenc-
ing any work.
Make sure the pump is depressurized.
Empty the pump, safely collect the pumped liquid and dam-
age it in accordance with environmental rules and requirements.
7.2.1 Maintenance in accordance with maintenance schedule
Perform maintenance work in accordance with the maintenance schedule (→ 9.3 Maintenance schedule, Page 29).
7.2.2 Cleaning the pump
NOTE
High water pressure or spray water can damage bearings!
