Pulsation dampeners reduce pressure fluctuation found in normal diaphragm and piston pump operation and can help eliminate material foaming, material pulsation, hydraulic shock or material splashing.






  • Automatic Air Adjustment - compensates for fluctuations in fluid pressure without operator intervention
  • Significant Pulsation Reduction - Shock blockers deliver an average 60 - 80% pulsation reduction in high back pressure applications
  • Built for High-Flow / Aggressive Fluid Applications - the 2" models can handle up to 159 cubic inch maximum fluid volume, and 3" models up to 509 cubic inch maximum fluid volume
  • Broad Material Range for Compatibility - choose from PVDF, polypropylene, groundable acetal (1" models) or aluminum, cast iron or stainless steel (2" and 3" models) body materials for optimum pump-to-pulsation dampener compatibility
  • Broad Diaphragm / Bladder Fluid Compatibility - choose from Santoprene, Nitrile, PTFE, Hytrel, Viton or Urethane for optimum fluid-to-diaphragm compatibility
  • Perfect for Process Applications - pulsation reduction in long piping runs help prevent costly fluid pipe and downstream valve damage
  • Bolted Construction - for leak-free vessel integrity and a safer work-site
  • Ultra-Rugged Construction for Long Service Life - both inside and out, the new Shock Blockers are built tough to deliver worry-free, near pulse-free fluid handling
