Safety
2 Safety
The manufacturer does not accept any liability for any damage caused by disregarding any sections of the entire documentation.
2.1 Intended use
• Only use the pump with suitable media (→ resistance lists).
• Do not use pump with solid particles or abrasive fluids.
• Do not use pump with combustible or explosive fluids.
• Adhere to the operating limits and size-dependent minimum flow rates.
• Avoid dry running:
Initial damage, such as destruction of bearings, seals and
plastic parts, will occur within a few seconds.
– Make sure the pump is only operated with, and never
without, pumped liquid.
• Avoid cavitation:
– Open suction-side fitting fully and do not use to regulate
flow.
– D o 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.
–Noteminimumflow (→ Data sheet).
• Avoid damage to the motor:
– D o 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 the man ufacturer about any other use of the pu mp.
• If pumps are delivered without m otors, then final assembly
as a pump assembly must take place in accordance with
the provisions of machinery directive 2006/42/EC.
Prevention of obvious misuse (examples)
• Observe pump limits of use regarding temperat
sure, flow and speed (→ Data sheet).
• The power consumption of the pump increases as the the
specific gravity of the pumped fluid increases. Adhere to
the permissible specific gravity in order to eliminate the
possibility that the pump, coupling and mo tor are overloaded (→ Data sheet).
A lower specific gravity is perm issible. Adapt the auxiliary
systems accordingly.
• When conveying fluids containing solids, observe the limit
values for proportions of solid particles and particle size
(→ Data sheet, technical description).
•Whenusinga

ure, pres-
• Pumps used with water as the pumped liquid must not be
used for foo dstuffs or drinking water. Use with food or
drinking water must be specified in the data sheet.
• Type o f installation should only be selected in accordance
with these operating instructions. For example, the following are not allowed:
– Hanging base plate pumps in the pipe
– Overhead installation
– Installation in the immediate vicinity of extreme heat or
cold sources
– Installation too close to the wall
2.2 General safety instructions
Observe of the followin g regulations 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
property.
• Only operate the pump if it is in perfect technical condition
and on ly use it as intended, staying aware of safety and
risks, and in adherence to the instructions in this manual.
• Keep this manual and all oth er applicable documents complete, legible and accessible to personnel at all t imes.
• Refrain from any procedures 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 add ition 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.

– 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.
Qualified personnel
• Make sure all personnel tasked with work on the pump
have read and understood this man ual and all other applicable documents, especially the safety, maintenance and
repair informatio n, before they start any work.
• Organize r esponsibilities, areas of competence and the
supervision of personnel.
• Ensure that all work is carried out by specialist t echnicians
only:
– Fitting, repair and maintenance work
– Transportation
– 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 fu nctionality:
– 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 chargi ng: provide suitable
grounding
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, 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
– Donotusethemasafixing point for winches or sup-
ports
– Do not use them for storing paper or similar materials
– Do not use hot pump or motor components as a heating
point
– Do not de-ice using gas burners or similar tools
• Do not remove the safety guarding for hot, cold or moving
parts during operation.
• Use p ersonal protective equipment if necessary.
• Only carry out work on the pump while it is not running.
• Before all installation and maintenance work, disconnect the mo tor from the mains and secure against being
switched back on again.
• Never reach into the suction or discharge flange.
• Following all work on the pump, refit safety devices in
accordance with the instructions and bring into service.
2.3 Specifichazards
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 carrying out any
work on the pump.
• Collect leaking pumped liquid and residues in a safe manner and dispose of i n accordance with en vironmental regulations.
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.
