Pulsation Dampeners -

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.
