High frequency pressure pulsation
High frequency pressure pulsation is dissipated by wide ratio of hole size through which it enters to diameter of chamber.

FLEXFLON or E.I. DuPont Teflon
FLEXORBER HP and FLEXORBER LP from hydro-formed dishings, with Flexflon, PTFE, or EIDP Teflon have the largest chamber diameter to port hole ratio - combine best HF pulse interception with flow velocity smoothing.

Dampers with no moving parts, & no foam to degrade or clog.

The WAVEGUARD H.O. Multi Chamber
no moiving parts dampener
By exploding pressure peaks through small holes
into large chambers pulsation is destroyed.

Helmholtz Orifice technology for greater efficiency

SELECTION is simply by connection, unless our associate LIQUID DYNAMICS International has completed an acoustic model study for you. (5) WAVEGUARD HO, uses the Helmholtz Orifice technology for greater efficiency for size.
(6) Is for particulate laden systems, & is larger.
(7) Is for the ultimate acoustic performance.

Where minuscule fluctuations in flow velocity are of little concern, and you simply need to prevent pressure pulsation & resonance, then WAVEGUARDS are THE answer.

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.
