What is the difference between a pulsation dampener, surge suppressor, inlet stabilizer, thermal expansion chamber, accumulator and standpipe?
These designations, with the exception of standpipe, are used to describe pressure vessels containing a flexible bladder or bellows inside that separate an inert pressurized gas (air or Nitrogen) from a system fluid in the lower chamber. Generally referred to as dampeners, their use and location in a liquid piping system determines the name designation. A standpipe is simply a pipe with a cap on one end, and does not separate a gas charge from the product being pumped.
