Burgess-Manning vacuum pump silencers are used with gas-flow vacuum pump systems where free liquid removal and noise control must be addressed as part of the same equipment selection.
Available for discharge applications, these silencer/separator designs may be configured for pressurized or atmospheric service depending on the requirements of the system.
Standard connection sizes range from 1″ to 30″ with custom design options available for application-specific needs.

For applications involving liquid-carrying gas streams, the vacuum pump silencer is designed to remove up to 99% of free liquid while also reducing noise generated through the vacuum pump discharge path.
Water separator/silencer designs direct gas flow through a separation section, ported tube, and snubbing chamber to remove liquid and attenuate noise over a wide frequency range.
Process Controls Corporation can assist with Burgess-Manning vacuum pump silencer selection for facilities evaluating discharge silencing, free-liquid removal, connection sizing, and pressurized or atmospheric service requirements.
