GENERAL

The Fluid Kinetics Liquid Pulsation Dampener reduces discharge pressure pulsation by approximately 75%. Actual performance depends on the type of pump, connected piping system, and liquid handled.

The spherical shape is strongest pound-for-pound in pressure-containing service . . . up to 6000 psi, design pressure is standard.

Maintenance free, the dampener can be permanently welded in the line, saving flange costs and potential flange leaks. Inline configuration eliminates special support problems.

DESIGN

Completely liquid filled, with no moving parts, this dampener does away with maintenance and gas charging requirements.

The stationary internals guide the incoming flow into a rotating path within the spherical shell. The spinning liquid mass creates a system smoothing effect. Viscous drag on the sphere walls and the capacitance effect of the relatively large volume located next to the pump, further aid to dampen pressure pulsation.

CONSTRUCTION

The dampener is all steel construction, with no bladders to fill or replace, and virtually no temperature limitation. With nozzles beveled for weld, the unit becomes a part of the piping.

Carbon steel construction is standard, but other materials are available.

APPLICATION

All power pumps produce pulsation. Whether or not the pulsation is severe enough to create problems depends upon many system variables. A few of these variables are the fluid handled, the type of pump and the pump speed. As a general guide, Fluid Kinetics engineers recommend using the Liquid Pulsation Dampener on several multi-plunger service type pumps having a discharge pressure over 500 psig, or on any service, regardless of pressure, whether pulsation problems are expected and a maintenance-free device is required.
