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
dstuffs or drinking water. Use for food or drink-
r only if specified in the data sheet.
sible. Adapt the auxiliary
etothe
ate the pos-
ome over-
• The type of installation should be selected only in accordance with these operating instructions. For example, the
following are not allow ed:
– Hanging base plate pumps in the pipe
– Overhead installation
– Installation in the immediate vicinity of extreme heat or
cold sources
– Installation too close to a wall
2.2 General safety instructions
Observe the following regul ations before carrying out any
work.
2.2.1 Product safety
The pump has been built according to state-of-the-art technology and the recognized technical safety regulations. Nevertheless, operation of the pump can still put the life and health
of the user or third parties at risk or damage the pump or other

and use it only as intended, staying aware of safety and
risks, and in adherence to the instructions in this manual.
• Keep this manual and all other applicable documen ts complete, legible and accessible to personnel at all t imes.
• Refrain from any pro cedures and actions that would pose
a risk t o p ersonnel or third parties.
• In the event of any safety-relevant faults, shut down the
pump immediately and have the fault corrected by appropriate personnel.
• In addition to the entire documentation for the product,
comply with statutory or other safety and accident-prevention regulations and the applicable standards and guidelines in the country where the pump is operated.

– Work on the electrical system
• Make sure that trainee personnel only work on the pump
under s upervision of specialist technicians.
Safety equipment
• Provide the following safety equipment and verify its functionality:
– For hot, cold and moving parts: pump safety guarding
provided by the customer
– For pumps without capability to run dry: Dry run pro-
tection
– For potential electrostatic charging: provide suitable
grounding
Warranty
• Obtain the ma nufacturer's approval prior to carrying out
any modifications, repairs or alterations during the warranty
period.
• Only use genuine parts or parts that have been approved
by the manufacturer.
• Following all work on the pump, refit safety devices in
accordance with the instructions and bring into service.
• Do not make any modifications to the device.
2.3 Specific hazards
2.3.1 Hazardous pumped liquids
• When handling hazardous fluids, observe the safety regulations for the handling of hazardous substances.
• Use personal protective equipment when carryi ng out any
work on the pump.
• Collect leaking pumped liquid and residues in a safe manner and damage them in accordance with environmental
regulations.
2.2.3 Obligations of personnel
• All directions given on the pump must be followed (and kept
legible), e.g. the arrow indicat ing the sense of rotation an d
the markings for fluid connections.
• Pump, coupling guard and components:
– Do not step on them or use as a climbing aid
– Do not use them to support boards, ramps or beams
– Do not use them as a fixing point for winches or sup-
ports
– Do not use them for storing paper or similar materials
– Do not use the hot pump o r motor components as a
heating point
– Do not de-ice the pump using gas burners or similar
tools
• Do not remove the safety guarding for hot, cold or moving
parts during operation.
• Use personal protective equipment if necessary.
• Only carry out work on the pump while it is not running.
• Before all installation and maintenance work, disconnect
the motor from the mai ns and secure it against being
switched back on again.
• Never reach into the suctio n or discharge flange.

5. Make sure the shaft and bearing change their rotational
position in the process.
4.3 Disposal
Plastic parts can be contaminated by poisonous or radioactive pumpe d liquids to such an extent that cleaning will be
insufficient.
WARNING
Risk of poisoning and environmental damage by the
pumped liquid or oil!
