Flo-Dyne Standard Discharge Pulsation Dampener

Pulsation dampeners are often necessary for multi-plunger high pressure reciprocating pumps which produce damaging levels of pulsation and vibration. These forces can be significantly reduced by the Flo-Dyne non-charged maintenance-free pulsation dampener which is completely filled with the pumped liquid. Our unique spherical in-line design results in optimized low weight and cost and is ideal where rubber bladder or metallic diaphragm types cannot be applied.

Should you require, for our standard dampeners, we can model your system, analyse the pulsation levels and simulate the mechanical response, with the same detail and rigour as needed by API674.

In many cases we can show you that a smooth running system can be achieved with dampeners that are smaller, lighter, and so cheaper, than that required by API674.

Volume

The volume is selected by Flo-Dyne to provide sufficient bulk so that when each plunger discharges its slug of liquid the compressibility of the liquid will absorb a proportion of the pulsation energy. The volume of the dampener must be chosen to be massive compared to the slug of liquid discharged by each plunger on each stroke, and not too large as to be uneconomical for manufacture.

Where required we can offer discharge pulsation dampeners that work upon this feature of compressibility of the volume alone, however such dampeners tend to be both massive and expensive.
