Safety
• Ensure that all work is carried out by specialist technicians
only:
– Fitting, repair and maintenance work
– Work on the electrical system
• Make sure that trainee personnel only work on the pump
under supervision of specialist tech nicians.
Safety equipment
• Provide the following safety equipment and verify its func-
tionality:
– For hot, cold and movin g parts: on-site safety guards
for the pump
– For possible electrostatic charges: provide the neces-
sary grounding
Warranty
• Obtain the manufacturer’s approval prior to c arrying out
any modifications, repairs or alterations during the warranty
period.
• Only use genuine parts or parts that have been approved
by the manufac turer.
Drive system
For pumps delivered without a drive system, comply with the
following requirements for the drive system:
• When using three-phase asynchronous motors, observe
IEC 60034 -30-1.
• Power of the drive acco rdi ng to EN ISO 5199 is recom-
mended (EN ISO 5199 also applicable fo r drive s of pro-
gressive cavity pumps).
• When using combustion engines, consult Allweiler.
• For pumps with stub shaft, connect drive system and pump
directly with stub shaft (special drives required)
•Useflexible coupling according to DIN 740-2.
• Use coupling guard with the fo llowing requirements:
– Fastening eleme nts must be connected to the pump
unit in undetachable design (cannot get lost).
– Safety distances agai nst the reaching of haza rdous
areas according to EN ISO 13857 must be complied
with.
2.2.3 O bligations of personnel
• All directions given on the pump must be fol low ed (and kept
legible), e.g. the arrow indicating t he sense of rotation and
the markings for fluid connections.
• Pump, safety guarding and compon ents:
– Do not step on them or use as a climbing aid
– Do not use them to suppo rt boards, ramps or beams
– Donotusethemasafixing poin t for win c hes or sup-
ports
– Do not use them for storing paper or similar materials
– Do not u s e hot pump or motor components as a he ating
point
– Do not de-i c e using gas burners or similar tools
• Do not remove the safety guarding for hot, cold or m oving
parts during operation.
• Use personal protective equipment whenever necessary.
• Only carry out work on the pump while it is not running .
• Isolate the motor from its supply voltage and secure it
against being s witched back on again when carrying out
any fitting or m aintenance work.
• Reinstall the safety equipment on the pump as required by
regulations after any work on the pump.
2.3 Specific hazards
2.3.1 Exp losion-hazard area
•(→ ATEX additio nal instructions).
2.3.2 Hazardous pumped liquids
• Follow the safety regulations for handling hazardous sub-
stances when handling hazardous (e.g. hot, flammable,
poisonous or potentially harmful) pumped liquids.
• Use protective equipment when carrying out any work on
the pump.
