PULSATION DAMPENERS

EQUAFLUX automatic diaphragm pulsation dampeners feature solid build and high performance. They are fitted to the discharge line of diaphragm pumps in order to smooth pulsating flows and can be used with liquids having apparent viscosity of up to 50000 cps (at 20°C) even if containing suspended solids of considerable size.
EQUAFLUX dampeners automatically adapt to system conditions without the need for manual adjustment or calibration.
The ability to minimise pulsations, vibrations and water hammer means that this component provides excellent protection and smooth system flow.
The huge choice of construction materials allows selection of optimum chemical compatibility with the fluid and/or environment without neglecting the temperature range. Dampeners are also available for use in potentially explosive atmospheres (ATEX certification).

Description of the dampener

Diaphragm pulsation dampeners consist of a pneumatic actuator connected to the new generation diaphragm (Long Life profile). The sturdy outer body forms the actuator’s compressed-air chamber for suppressing pressure surges on one side of the diaphragm and the chamber through which the fluid flows on the other. A = expansion opening B1 = air-side diaphragm B2 = fluid-side diaphragm C = automatic pneumatic valve D = compressed-air chamber

How it works

The compressed air entering the back-pressure chamber behind the diaphragm creates a pneumatic cushion that adjusts automatically to compensate the shock produced by the pressure pulse of the fluid generated by the pump.

Installation

Diaphragm dampeners should be installed on the discharge side of pneumatic pumps or where pressure surges in the fluid occur.

Chemical compatibility

The type of liquid, temperature and working environment are factors to be considered when deciding on the best choice of construction materials for the pump and its correct chemical compatibility. The table below gives some examples of the most commonly-used substances:
