Pulsation Dampeners -Typical Applications |
|
Suction Stabilization |
 |
When installed on the upstream side of positive displacement pumps, suction stabilizers
help in eliminating cavitation problems by smoothing out the flow of the fluids into the
pump cylinders. Cavitation can cause premature wear to valves, seats, plungers and other
pump components.
Integrated Equipment Pulsation Dampener's when mounted close to the inlet or suction flange of the pump
ensure complete filling of the cylinders during each stroke. |
|
Pulsation Dampening |
 |
Pressure surges or pulsations on the discharge side of positive displacement pumps cause
vibrations and fatigue failures of major pump parts such as valves, seats and plungers. If
not addressed, these vibrations can cause fatigue failure of downstream pipe, pipe supports
and other critical components and equipment.
An Integrated Equipment Pulsation Dampener, appropriately-sized and mounted near the discharge
flange, will assist in dampening the pressure surges/pulses on the discharge side of
the pump prolonging the life of the pump fluid end components as well as critical downstream
equipment. |
|
Surge Absorption |
 |
Surges in fluid systems caused as a result of sudden valve closures, pump shut-downs
or start-ups, can lead to pressure build-ups that are large enough to rupture piping,
piping supports and damage downstream equipment. This phenomenon, also known as
water hammer, results from the sudden change of kinetic energy (of the flowing fluid) to
pressure energy.
An Integrated Equipment Pulsation Dampener, mounted at an appropriate location, can assist in absorbing
these surges thereby saving costly equipment failures or replacements. |
|
Back Surge |
 |
When the elevation heads of pumps are high, back surges can be caused as a result
of sudden pump shut-downs when the fluid flows back slamming into the pump or
check valve.
Integrated Equipment Back Surge Pulsation Dampeners installed close to the valves, help in absorbing the surge. |
|
Energy Storage |
 |
Due to the design of the Integrated Equipment Pulsation Dampener it can be used as an energy storage
device (Accumulator) in a hydraulic system. An Integrated Equipment Pulsation Dampener, appropriatelysized,
can be used to supply hydraulic power for a short period of time. This is critical in lube
oil systems which must supply lube oil to critical rotating equipment where an interruption
can cause costly failure not only to the equipment but also the potential shutdown of the
downstream operation. |
|
Special Application |
 |
Integrated Equipment Pulsation Dampeners/Accumulators can also compensate for leakages in a hydraulic
system as well as compensate for any pressure change due to thermal expansion. |
