Take the pulse out. Keep the system running.
ARO Shock Blocker pulsation dampeners take up to 90% of the pulse out of your system before it reaches your piping, your instruments or your team — sized and tested for the EVO210, backed by a single Ingersoll Rand warranty, available through a global distribution network.
Why ARO Shock Blocker?
The accessory that completes your pump system.
Every diaphragm pump pulses by design — AODD and electric alike. Without a pulsation dampener, those pressure fluctuations propagate through your piping, hammer your fittings, drift your flow meters and pressure transmitters, and shorten the service life of every downstream component. The maintenance team feels this as unexplained leaks, batch inconsistencies and unplanned shutdowns.
ARO Shock Blocker pulsation dampeners take up to 90% of that pulse out before it reaches the rest of your system. The family now covers three categories — Passive, Adjustable and Active — across a full range of housing materials from GF-Polypropylene and PVC through PVDF and 316L stainless steel. Whether your process fluid is water, lubricant, aggressive solvent or a hygienic pharmaceutical stream, there is a Shock Blocker chemistry configuration to match.
New for 2026: five passive and adjustable SKUs sized and tested specifically for the ARO EVO210 electric diaphragm pump — the first ARO-branded passive dampeners available for electric pump installations. Pair them with your EVO210 pump, ARO FRL units and the rest of the ARO fluid-handling family, and let one brand stand behind the whole solution — from pump inlet to pipe discharge.
