Safety information
WARNING!
ATEX pumps in areas at risk from explosion
– Generally ensure proper functioning (no leaks,
unusual noises, high temperatures, unusual
smell, vibrations, etc.) especially of the power
end/drive and the bearings.
– Do not allow the pump to heat up because of
lack of oil!
With lubricated metering pumps, regularly
check for the presence of lubricant, for
example by checking the liquid level, visual
leak control etc. If oil is leaking, examine the
leakage point immediately and eliminate the
cause.
– Only use a moist cloth when cleaning plastic
parts to avoid electrostatic charge.
– Replace wear parts, such as bearings, when
there is an identifiable incidence of unaccept‐
able wear. (The nominal service life cannot be
calculated with lubricated bearings.)
– Only use genuine spare parts as replacements.
WARNING!
ATEX pumps in areas at risk from explosion
Static electricity can cause ignition sparks.
– Consider potential equalisation before you
approach any pump equipment that could be at
a different electrical potential (such as pipes or
tools)
WARNING!
Fire hazard with flammable media
Only with flammable media: They can be ignited by
oxygen.
– The pump may not work if there is a mixture of
feed chemical with oxygen in the liquid end. A
specialist may need to take appropriate actions
(using inert gas, ...).
WARNING!
Danger of an electric shock
Personnel working on electrical parts can be elec‐
trocuted if all electrical lines carrying current have
not been disconnected.
– Disconnect the supply cable before working on
the motor and prevent it from being recon‐
nected accidentally.
– Any separately driven fans, servo motors,
speed controllers or diaphragm rupture sen‐
sors fitted should also be disconnected.
– Check that the supply cables are de-energised.
