2.1  Intended use 

The pump is intended solely for the following uses: 

  Transferring liquids and gases 

  For operation in accordance with the operating parameters 

specified in the technical data of the supporting documents 

2.2  Reasonably foreseeable misuse 

The pump must not: 

  be operated in an explosive atmosphere 

  be used to transfer explosive media 

  be used to transfer media whose compatibility with the pump 

head, valves, diaphragm, and seals has not been proven 

2.3  Responsibility of the user 

The user is responsible for ensuring that the safety precautions in 
these Installation Instructions are complied with. Applicable safety, 
accident prevention, and environmental protection regulations must 
be complied with.  

2.4  Product-specific risks 

Remaining risks that were determined in a risk assessment are de-
scribed in this section. Safety precautions and warnings in this sec-
tion and in the other sections of the Installation Instructions must 
be observed to prevent dangerous situations.  

 

 

DANGER 

Danger of injuries and damage to property due to dangerous 
substances 

Poisoning and chemical burns or unintended reactions caused by 
leaking dangerous substances 

  Observe the safety data sheets of the transferred media. 

  Before transferring a medium, check whether it can be 

transferred safely in the specific application case. 

  Ensure that the system is not subject to any risks of explo-

sion 

– not even under extreme operating conditions (tem-

perature, pressure) or in case of malfunctions. 

  Ensure the pump is used only by suitably trained, skilled 

employees. 

  Clarify the chemical resistance of the head materials. 

  Check that the pump and the system do not leak at the op-

erating temperature of the transferred medium. 

  Check the pump for damage regularly. 

  Operate the pump only when you are sure it has no tech-

nical malfunctions. 

  Operate the pump in accordance with the technical data. 

  Work on the pump or fluid circulation system only after they 

have been decontaminated and/or a decontamination decla-
ration is present.
