Surge Suppressor Kit
The surge suppressor kit smooths out the ripple caused by the pulsing action of
the pump as it pressurizes the hydraulic fluid. The surge suppressor is a cylinder
that has an outer sleeve that is pressurized with nitrogen. The gas pressurized
sleeve dampens the pressure pulses.
The surge suppressor is mounted to the output of the hydraulic pump inside the
reservoir.
