Residual risks
Explosion danger
Pumps with conductive Acetal parts in contact with
media may not be used with acids and lyes. Reac-
tion and explosion of these materials can cause
serious injury or death. Reaction and explosion of
these materials can cause serious injury or death.
Pump motor section
Fluid caps
Distributor
Parts in contact with material
Sparks due to electrostatic discharge
If the pump is not properly grounded or the poten-
tial equalization fails, components may get
charged electrostatically. Electrostatic discharge
can cause sparks that in explosive atmosphere
can cause a fire or an explosion. Serious injury
and death could be the consequence.
Ground Pump as specified.
Check connection of grounding cable during
operation.
Measure volume resistivity.
Media
Material escaping under pressure can cause
serious injuries.
Before working on the product:
Disconnect the system, in which the product is
installed, from compressed air and material
supply.
Depressurize the lines.
Secure the system against being switched on
again.
Observe approved operating pressures
2.4
Conduct in the event of a hazardous
situation
Conduct in case of danger depends on the opera-
tor’s installation situation.
Perform the following activities:
Close lines.
Secure against reconnection.
Depressurize lines.
