Vacuum Pump Silencers

Dürr Universal’s vacuum pump liquid separator silencers are used to remove liquid from gas flow vacuum systems for either liquid-sealed rotary positive blowers or liquid ring vacuum pumps.

Vacuum pump silencer application areas

Separator silencers may be required for both the inlet (vacuum) and the discharge (atmospheric) of a vacuum system. Only the most stringent acoustical environments require significant inlet silencing. An inlet separator provides corrosion protection for the vacuum pump by removing most, if not all, of the process liquid before it enters the vacuum pump. The vacuum pump or blower discharge is normally extremely noisy and requires a high performance separator silencer. Dürr Universal vacuum pump silencers meet the needs of these demanding applications. For application information, please contact us.

Vacuum pump silencer models

Dürr Universal offers several models of separator silencers for inlet and discharge applications.
