Pulsation Dampeners

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

Product Information

Diaphragm pumps of any type have at least two points in their cycle
where they provide no pressure or flow to a process. The unwanted
result of this pressure fluctuation can often be material foaming,
material pulsation, hydraulic shock, or material splashing. While traditional pulsation dampeners can help reduce unwanted pulsation and other
problems, they also require operator intervention and adjustments.

Features

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
