Hughes Pumps has increased the
working pressure of four of its
pumps designed for water jetting
applications from 1000 to 1400 bar
(20,000 psi). The greater water jet
velocity produced delivers increasing
cutting efficiency with a
corresponding reduction
in flow-rate that reduces
the reaction force to
more comfortable levels.

When using UHP for
hydro-demolition/
concrete cutting it
removes only the
concrete so does not
damage the rebar
underneath; it is said to be faster
than conventional methods; and
there is no vibration so neither
micro cracks nor fractures develop
on the remaining concrete structures.
