The WAVEGUARD range of 3 types by PULSEGUARD
Guard against pressure waves Guard against pulsation
3 varients of Pressure Pulsation Damper with no moving parts, no foam to clog or degrade.
Designed to address Pressure Pulsation, (not flow fluctuations) with high frequency pumping systems. 1. WAG-Cer, w/Ceramics 2. WAG-HO Orifice tech. 3. WAG-MT. Liquid Compressibility
Index Page of All WaG-Cer Options - prices/dimensions, application story, dimensional drawing...

The differential area form valve seat diameter to the pump chamber, to the outer seat diameter to the system, causes the check valve not to open until up to a 60% pressure differential. The release of these 60% over pressure spikes into the system produces high frequency pressure pulsation.
Type 1 in clean systems "WaG-Cer"
Type 2 in systems that can tolerate some pressure drop "WaG-HO".
Type 3 - they are much larger - for liquids that are no clean "WaG-Mt"
"WAG-HO" WAVEGUARD Multi Chamber
A gradual transition from system connection to orifice diameter at a 7 degree * taper ensures that do not bounce the pressure pulsation back into the system.

tries to compress some almost totally trapped liquid, to a very high pressure. The decompression escape back through the gear tolerance gap, makes a pressure spike.

By exploding pressure peaks through small holes into large chambers pulsation is destroyed.
WAVEGUARD Ball path Disperser
By causing the pressure waves to travel down many paths of different length, the time base of a transient peak is spread, and so its height is removed.


The compressibility of the liquid and the amount of entrained gases, can be made to work to your advantage.
When installed in a gravity draining orientation, these WAG-MT dampers may be used on particulate contaminated systems.
The diameter of the sphere to the diameter of the inlet and outlet connections is a vital ratio for the pulse reduction coefficient.
The parts of a litre volume change per bar pressure change, is an essential "compressibility" figure used in "WAG-MT" selection.

The volume of slightly compressible liquid accumulates flow fluctuations. The deadening effect of the liquid mass helps to reduce pressure pulsation.

Selecting Pulsation Dampeners for Different Pump Systems.
Flow through pulsation dampers are at least 3 times more efficient than T off line accumulators.
Dampeners that do, flow goes through, but pressure pulsation does not.
