Pulsation Dampeners Installation for Gear Pumps

Pulsation Dampeners for Gear Pumps Selection of Pulsation Dampeners, from Pre-engineered Models, for Installation with Gear Pumps by Connection Size

Pulsation Dampeners for Gear Pumps Smoothness needs of a typical gear pump application A. Low Pressure Jacketed FlexOrber Dampener with PTFE diaphragm B. High Pressure Jackated FlexOrber Dampener with metal diaphragm Example: High Viscosity Resin / Polymer In tank with hot oil Jacket MAKE FLOW. The only pump vendor responsibility LP Pulsation Dampener makes suction flow to the meter constant. Jacketed double layer diaphragm feed pump creates flow fluctuation. Heating circuit pump, no pulsation dampener required but see: "Expansion & Contraction Compensator" Example: 23 tooth gear pump, minimum chance of resonance. Lifts pressure from 50 Bar, and provides precise flow within 0.5% Das PumpHaus "The True Meter Pump" HP Pulsation Dampener Jacketed Liquibello by ShockGuard - Metal Bellows Expansion and Contraction Compensation Flow Through - in place flush - Metal Diaphragm Ripple Removal to within 0.1% Spinnerette Heads 0.1% DQ Denier Checked By Laser Beam Precisely Web Coating

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

Gear Pump
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.

Pulsation Dampener on a Gear Pump
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:- High Pressure Pulsation Dampeners price list of off the shelf inventory dampeners with dimensions and weights.

Pulsation Dampener for Gear Pump
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.

Pulsation Dampeners for Gear Pumps
HP Pulsation Dampeners and LP Pulsation Dampeners 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.

Select fluid control pulsation dampeners for your system only after you know how to connect them
When you see pulsation dampeners, reciprocating pumps, rotary pump, or other hardware type of interest, request literature dedicated to that dampening subject ( 1-888-DAMPERS )

Pulsation dampeners are designed to address pressure pulsation, which is caused by the resistance of the system to flow. Therefore, our pulsation dampeners focus on the system related responsibility and are less related to pump liability.
PUMPS make FLOW, SYSTEMS cause PRESSURE, pressure pulsation is a system response, AND a system responsibility NOT a pump manufacturers liability.
