Pumps with cooling jackets must be vented! The
screw plug 903.02 must be released. After ventilation,
the screw plug must be tightened again.
5.3. Use of chains
Chains are used to lower a pump in the operating space
or to pull it out.
They are not intended to secure a floating pump. Intended
use is as follows:
•
Fasten one end of the chain on the handle of the
pump provided for this purpose. If your pump has
two ring bolts as an attachment point, you must use
a double-strand chain. When doing so, the angle of
inclination of the chain strands must be between 0°
and 45°.
•
Attach the other end to the lifting device.
•
Ensure tension on the chain, and then lift the pump in
a slow and controlled manner.
•
Swing the pump then over the operating space and
lower it gently. When using a suspension unit, ob-
serve chapter. 5. Commissioning.
•
Lower the pump to the operating point from and
make sure that the pump has a secure footing or the
coupling system is engaged correctly.
•
Remove the chain from the lifting device and secure
it to the safety chain, which is located at the top of
the operating room. This ensures that the chain can
not fall into the operating area and constitutes a dan-
ger to anyone.
