IR ARO announces an important addition to their line of Shock Blocker Pump Pulsation Dampeners. Designed for aggressive process fluid applications, the new Shock Blocker 2" and 3" port models feature an automatic adjustment valve that provides consistent, continuous pump pulsation reduction, according to the manufacturer.

First introduced to market in 1990, the Shock Blocker 1" (port) non-metallic models created an important breakthrough in fluid pulsation management by combining critical features like enlarged air chambers and fracture-resistant fluid inlets with a patented Air-Tamer automatic air adjust assembly that allowed the operator to "set it and forget it." Built with many of these same critical features, the new 2" and 3" metallic models continue the tradition of compatibility, convenience and consistency that has become the Shock Blocker benchmark.

Shock Blocker 2" and 3" Features:

  • Automatic Air Adjustment- compensates for fluctuations in fluid pressure without operator intervention
  • Significant Pulsation Reduction- the new Shock Blockers deliver an average 60% pulsation reduction at 150 GPM flow with 60 PSI back pressure
  • Perfect For Process Applications- pulsation reduction in long piping runs help prevent costly fluid pipe and downstream valve damage
  • Built for High-Flow/Aggressive Fluid Applications- 2" models can handle up to 159 in.3 maximum fluid volume, and 3" models up to 509 in.3 maximum fluid volume
  • Broad Pump Compatibility- choose from aluminum, cast iron or stainless steel body materials for optimum pump-to-pulsation dampener compatibility
  • Broad Fluid Compatibility- choose from Santoprene®, Nitrile, Teflon® or Urethane for optimum fluid-to-diaphragm compatibility
  • 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, pulse-free fluid handling
