General safety instructions
2 General safety instructions
The manufacturer accepts no liability for damages caused
by disregarding any of the documentation.
2.1 Intended use
• Only use the pump with suitable media. Pump parts in con-
tact with media must be resistant to the media. (→Order
specification).
• Adhere to the operating limits and size-dependent mini-
mum flow rates.
• Avoid dry running:
Initial damage, such as destruction of plain bearings, seals
and plastic parts, will occur within a few seconds.
– Make sure the pump is only operated when filled with
the conveyed fluid and never operated when not filled
with the pumped liquid.
– Ensure that there are no excessively high amounts of
gas in the pumping medium.
– Ensure that the pump is operated only within the per-
missible operating range.
– Ensure that the use of shut-off valves or filters does not
cause the pressure on the inlet side of the pump to be
too low.
• Avoid cavitation:
– Fully open the suction-side fitting, if installed.
– 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 minimum 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.
Prevention of obvious misuse (examples)
• Observe pump limits of use regarding temperature, pres-
sure, flow and speed (→data sheet).
• The power consumption of the pump increases as the spe-
cific gravity of the pumped fluid increases. Adhere to the
permissible specific gravity in order to eliminate the pos-
sibility that the pump, coupling and motor become over-
loaded (→data sheet).
A lower specific gravity is permissible. Adapt the auxiliary
systems accordingly.
• Do not convey any media containing solids.
• The type of installation should be selected only in accor-
dance with these operating instructions. For example, the
following are not allowed:
– Hanging pumps in the pipe
– Overhead installation
– Installation in the immediate vicinity of extreme heat or
cold sources
– Installation too close to a wall
– Vertical installation
2.2 General safety instructions
Observe the following regulations before carrying out any
work.
2.2.1 Product safety
The pump has been built according to state-of-the-art technol-
ogy and the recognized technical safety regulations. Never-
theless, 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
property.
• Operate the pump only if it is in perfect technical condition
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 documents com-
plete, legible and accessible to personnel at all times.
• Refrain from any procedures and actions that would pose
a risk to personnel or third parties.
• In the event of any safety-relevant faults, shut down the
pump immediately and have the fault corrected by appro-
priate personnel.
• In addition to the entire documentation for the product,
comply with statutory or other safety and accident-preven-
tion regulations and the applicable standards and guide-
lines in the country where the pump is operated.
2.2.2 Obligations of the operating company
Safety-conscious working
• Operate the pump only if it is in perfect technical condition
and use it only as intended, staying aware of safety and
risks, and in adherence to the instructions in this manual.
• Ensure that the following safety aspects are observed and
monitored:
– Intended use
– Statutory or other safety and accident-prevention reg-
ulations
– Safety regulations governing the handling of haz-
ardous substances
– Applicable standards and guidelines in the country
where the pump is operated
– Applicable guidelines of the operator
• Make personal protective equipment available.
6SMP 11335/0320

General safety instructions
Qualified personnel
• Make sure all personnel tasked with work on the pump
have read and understood this manual and all other appli-
cable documents, especially the safety, maintenance and
repair information, before they start any work.
• Organize responsibilities, areas of competence and the
supervision of personnel.
• Ensure that all work is carried out by specialist technicians
only:
– Installation, repair and maintenance work
– Transportation
– Work on the electrical system
• Make sure that trainee personnel only work on the pump
under supervision of specialist technicians.
Safety equipment
• Provide the following safety equipment and verify its func-
tionality:
– For hot, cold and moving parts: pump safety guarding
provided by the customer
– For pumps without capability to run dry: Dry run pro-
tection
Warranty
• Obtain the manufacturer'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.
2.2.3 Obligations of personnel
• All directions given on the pump must be followed (and kept
legible), e.g. the arrow indicating the sense of rotation and
the markings for fluid connections.
• Pump 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 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 mains and secure it against being
switched back on again.
• Never reach into the suction or pressure-side flange.
• 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 regu-
lations for the handling of hazardous substances.
• Use personal protective equipment when carrying out any
work on the pump.
• Collect leaking pumped liquid and residues in a safe man-
ner and damage them in accordance with environmental
regulations.
2.3.2 Magnetic field
Individuals with implanted pacemakers must:
• Be kept away from the pump with magnetic coupling and
parts of the magnetic coupling
• Not be allowed to complete work with, or on, the magnetic
parts
The magnetic field of the magnetic coupling can destroy prod-
ucts that are sensitive to magnets. These include
• Pacemakers
• ID cards with magnetic strips
• Credit cards and check cards
• Electrical, electronic precision devices (e.g. mechanical
and digital clocks, calculators, hard disk drives)
