In their instruction manuals, practically every manafacturer throughout the world of the above mentioned types of pump advices the installation of a flexible section of piping upstream from the pump for the purpose of isolating possible vibration and facilitating the pumps maintenance.
The installation of a FEXODAMP pulsation damper guarantees the above memtional recommendation in additional to providing a constant flow that decreases the pulse effect of the pumps, with an effectiveness of up to 95%
The online pulsation damper has a double function in pulsating flow installations.
The workign principle is very simple. When the damper is not working the compressed air that has entered the inner and outer tube compresses the inner tube. (Figure 1)
When the pump pulses fluid, part of the fluid expands the inner tube, occupying the area that the compressed air occupied. (Figure 2)
The previous process is repeated automatically at the end of the pulse, the flow being linearised as a result of this method being used. Being totally flexible, it absorbs all the vibrations and hammering that may occur.
