DANGER! Risk of fatal injury!
The pump itself and the pump parts can be extremely heavy. Falling
parts pose a risk of cuts, crush injuries, bruises or impacts, which
may lead to death.
• Always use suitable lifting equipment and secure parts against fall-
ing.
• Never stand beneath a suspended load.
• The safety zone must be marked so that there is no danger when
the load (or part of it) slips away or if the hoisting gear snaps or is
ripped off.
• Loads must never be suspended for longer than necessary.
Accelerations and braking during the lifting operation must be
done so that danger to people is ruled out.
WARNING! Danger of bodily injury!
Improper transport can lead to personal injury.
• When lifting machines or parts using lugs, only hooks or shackles
can be used which meet the local safety regulations. The holding
chains/ropes must never be guided over or through sharp edges
without protection.
• When lifting, make sure that the load limit of a rope is reduced
when pulling at an angle.
• The safety and efficiency of a rope is best guaranteed when all
load-bearing elements are loaded as vertical as possible.
• If necessary, use a lifting arm, to which the attachment rope can be
vertically attached.
• If block and tackle or similar hoisting gear is used, vertical lifting of
the load must be ensured.The suspended load must be prevented
from swinging. This can be achieved, for example, by using a sec-
ond block and tackle, whereby the relative pulling angle to the ver-
tical must be less than 30° in both cases.
The interior parts of the pump are protected by a corrosion-protec-
tion film. This must be removed before commissioning. For this, fill
and empty the pump several times with a suitable product (e.g. petro-
leum-based solvent or an alkaline cleaning agent), and rinse with
water, if necessary.
WARNING! Danger of bodily injury!
Improper handling of solvents or cleaning agents can lead to bodily
injuries and environmental damage.
• Take all precautionary measures to avoid risks to personnel and the
environment during this operation.
• The pump must be installed and put into operation immediately
after this operation.
If the pump is stored for longer than 6 months, the corrosion protec-
tion film for protecting the inner parts of the pump must be applied
again regularly.Contact the manufacturer with regard to choosing
suitable products.
