3 Introduction
3.1 Applications and purpose of use
Flowrox Expulse™ is a flexible inline pulsation dampener,
which smoothes noises, restless pipes, pressure peaks and
uneven flows. The design is based on double hose structure;
damping hose, cover hose and compressed air in between. It
may be installed on a pulsating pump from any manufacturer
in the market.
The dampener is self-cleaning and does not collect sediment
or particles. It is resistant to wearing, corrosion and most
chemicals.
Flowrox Expulse™ provides a flexible connection to the pump
and tolerates possible misalignments in the pipeline. The
dampener can also be easily removed if needed.
Restrictions on use for Expulse™ dampeners
The dampener temperature and pressure range must not be
exceeded. The temperature ranges are given in Table 2 for
standard hose materials.
The maximum operating pressure for the Expulse™
dampeners is 10 bar (1 MPa). Do not use higher pipeline
pressure than rated for the dampener.
The maximum filling air pressure between outer and inner
hoses is 6 bar (0,6 MPa)
