Gear Pump Pulsation Dampener Installation Information

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

1. 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.

Pulsation dampeners with no moving parts, and no foam to degrade or clog.
"Maintenance free dampeners " An admission that pulsation is acoustic not volumetric.
6. WaveGuard/MT is for particulate laden systems and is larger. 7. WaveGuard/Cer is for the ultimate acoustic performance. It has ceramic balls and breaks pressure waves. 5. 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.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.

PulseGuard Pulsation Dampeners
Dampeners that do, flow goes through but pressure pulsation does not.

PulseGuard pulsation dampeners are designed to address pressure pulsation, which is caused by the resistance of the system to flow. Therefore our dampeners focus on the system related responsibility and are less related to pump liability.
