Prevention of obvious misapplication (examples)
• Observe and comply with the operating limits of the pump in terms of temperature, pressure,
delivery rate (
→
Appendix, table 2; contract data).
• The power consumption of the pump increases with increasing density or viscosity of the liquid. To
prevent an overload of the pump, coupling and motor, comply with the permissible viscosity and
density (
→
Appendix, table 3, table 4). A lower density and viscosity is allowed.
• When pumping fluids containing solids, maintain the limit values for solid contents and grain size (
→
Contract data sheet, technical description).
• Possible chemical reactions of fluids and resulting health hazards and material damage must be
considered.
• Motors may only be operated mounted to the pump tube (
→
operating instructions motor).
• Pump with universal motor must not be exposed to weather or be splashed with liquid.
• Use hoses only in perfect and tested condition (
→
operating instructions hose lines).
• For pump tubes made of PVDF following applies:
- Do not operate in explosion hazard area.
- Do not pump flammable liquids.
2.3 Specific danger

Chapter 10: Instructions for the explosion protection
• Only use pump tubes made of stainless steel (SS 1.4571 with ATEX-Identification II 2 G Ex h IIB T4 Gb.
• Only use explosion-proof drive motors.
• Only operate the pump in filled condition.
2.3.2 Dangerous media
• When pumping dangerous media (e.g. hot, flammable, explosive, poisonous, dangerous to health)
observe safety provisions for handling hazardous substances.
• Consider the safety data sheet of the product.
• Always wear protective equipment when working on the pump.
2.3.3 Mechanical hazards
• Pump protrudes from the container and must be protected against mechanical influences.
• The pump must not be transported together with the container.
