SENTRY™ dampeners are pressure vessels
containing a flexible bladder or bellows inside that separates an inert pressurized gas
(air or Nitrogen) from a system fluid in the lower chamber. Depending on how dampeners are configured, they are used as
Pulsation
Dampeners, Inlet Stabilizers or Surge Suppressors
to control pressure fluctuations and spikes in liquid piping systems.
Dampeners work on the principle that volume is inversely proportional to pressure (P
1
V

=P

V

). Compressed air or Nitrogen (never
Oxygen) is introduced into the non-wetted side of the dampener. The gas charge is contained by the bladder or bellows preventing
contact between the system fluid and the gas.
When the dampener is sized correctly, properly installed and charged according to the instructions provided it will greatly reduce the
damaging effects of pressure variations in piping systems and significantly improve the efficiency of transferring liquids.
All dampeners manufactured by BLACOH use pressure bodies made in the USA to ensure quality. Prior to shipment, each
and every dampener is factory pressure tested to assure proper function and leak-free operation.
