3.2 General description
Principle of operation
The wetted parts of Flowrox Expulse™ dampener are built
from stainless steel and NR as a standard structure. The hoses
are overlapping creating an air tight space between them. This
space is pressurized with oil free compressed air.
The Expulse dampener provides full bore through which
the medium can travel. The main components are shown in
Figure 1 and Figure 2.
The dampening effect can be adjusted with the air pressure.
Normally the needed pressure is 25-40% from the pipeline
pressure.
