Pumping combustible liquids.
Experience has shown that
dangerous charges are not
likely at ow velocities > 7m/s
(TRGS 727).
The cross-section of the compressed
air supply must not be smaller then the
connection on the pump.
For simple removal of the pump a shut-

■ The weight of the pipeline must be
taken up before the pump.
■
Elongation compensators must be
installed to compensate any elongation
of the pipes caused by temperature
increase.
Note:
It is recommended to
install flexible, shape and
pressure resistant hoses or
