Treatment of noise created by high pressure multi-plunger hydraulic pumps, is achieved by the application of a low pass design acoustic filter, acoustic filterwhich is designed to attenuate the dominant frequency and the most significant harmonics.
Each acoustic filter can be built to be welded directly into the piping with connecting nozzles supplied bevelled and ready for welding to the pipe system, or each unit may be supplied with couplings or flanges to match the mating connection.
The multi-chambered acoustic filter is designed to filter or attenuate the predominate frequency and significant harmonics of the pump. Using computer simulation response curves, Flo-Dyne engineers can check each acoustic filter design for each application.
