Safety-conscious operation
• Ensure that the following safety aspects are observed and monitored:
– Intended use
– Statutory or other safety and accident-prevention regulations
– Safety regulations governing the handling of hazardous substances

applicable 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:
– Fitting, repair and maintenance work
– Work on the electrical system
• Make sure that trainee personnel only work on the pump under the supervision of specialist technicians.
Safety equipment
• Provide the following safety equipment and verify its functionality:
– For hot, cold and moving parts: on-site safety guards for the pump
– For possible electrostatic charges: provide the necessary grounding

• Power of the drive according to EN ISO 5199 is recommended (EN ISO 5199 also applicable for drives of
screw pumps).
• For stub shaft coupled pumps (LPD and ACD) connect motor and stub shaft directly.
• For other series use elastic coupling according to DIN 740-2.
• Use coupling guard with the following requirements:
– Fastening elements must be connected to the pump unit in undetachable design (cannot get lost).
– Safety distances against the reaching of hazardous areas according to EN ISO 13857 must be
complied with.
Obligations of the operating company
• 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
– Do not use them as a fixing point for winches or supports
– 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 guards for hot, cold or moving 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 switched back on again when carrying
out any fitting or maintenance work.
• Reinstall the safety equipment on the pump as required by regulations after any work on the pump.
