Fawcett Christie Alleviators are designed to control  surge by providing an elastomer bladder precharged  with nitrogen, contained in a steel shell. 
 The pressure surge, partially dampened by the  orifices in the alleviator fluid port, enters the shell,  where the remaining kinetic energy is dissipated by  compressing the nitrogen gas within the bladder.
 Fawcett Christie Alleviators are totally enclosed and  as the only moving part is the bladder therefore little  maintenance is required.
 Applications include:
- Pump Shut-down 
- Pump Start-up 
- Valve closure 
 (further details regarding applications available on  our technical datasheet) 
 Specifications
- Carbon or Stainless Steel 
- Design pressures up to 34.5 bar
