Pulsation Dampeners Installation for Gear Pumps

How to ensure lowest in place cost and most performance by standard installation methods.

Removing the ripple from gear pump piping
1. How it starts
2. A partial fix
3. True solution - with elastomers
4. With PTFE or "FlexFlon"
5. No particulate
6. With dirt
7. Big but best

Even these, THE SMOOTHEST of all POSITIVE DISPLACEMENT PUMPS have pressure disturbances, which are normally not important, but when they are connected to piping systems that were not designed, will cause pulsation

The final full meshing of the gear tooth tries to compress some almost totally trapped liquid, to a very high pressure. The decompression escapes back through the gear tolerance gap and makes a pressure spike.

High frequency pressure pulsation is dissipated by wide ratio of hole size through which it enters to diameter of chamber. FOR A PARTIAL FIX when stainless and an elastomer are compatible GO TO:- price list of off the shelf inventory dampeners with dimensions and weights.

A better solution, larger diameter than #2. When metal & elastomer are compatible GO TO:- PipeHugger HP price list of off the shelf inventory dampeners for dimensions, weights and drawings.

and from hydroformed dishings, with "FlexFlon" or E.I. DuPont Teflon have the largest chamber diameter to port hole ratio - combine best HF pulse interception with flow velocity smoothing. GO TO:- FlexOrber price lists of off the shelf inventory pulse dampeners for dimensions, weights and cut sheet drawing.

Pulsation dampeners with no moving parts, and no foam to degrade or clog.

"Maintenance free dampeners" An admission that pulsation is acoustic not volumetric.

Application: Where miniscule fluctuations in flow velocity are of little concern, and you simply need to prevent pressure pulsation and resonance, then WaveGuard is the answer. GO TO:- The price dimension & weights tables for drawings. Selection is simply by connection, unless our associate Liquid Dynamics International has completed an acoustic model study for you.

The WaveGuard/HO uses the Helmholtz Orifice technology for greater efficiency for size. The answer to high pressure, medium high frequency, low volumetric pulsation, and for systems without suspended solids. By exploding pressure peaks through small holes into large chambers pulsation is destroyed.

WaveGuard/MT is for particulate laden systems and is larger.

WaveGuard/Cer is for the ultimate acoustic performance. It has ceramic balls and breaks pressure waves.
