SENTRY Pulsation Dampeners & Arrestors

Dampeners and Suppressors

remove hydraulic shock and vibration, enhancing all-around performance and reliability of fluid flow applications.
Positive Displacement (PD) pumps create pulsation and hydraulic shock due to the reciprocating nature of their stroking action, potentially damaging the entire pumping system.

BLACOH's SENTRY Pulsation Dampeners & Surge Suppressors remove virtually all hydraulic shock, enhancing all-around performance and reliability of fluid flow in industrial and chemical transfer applications.

FDA compliant MATERIALS and easy to clean for sanitary or food applications.

Reduce pulsation, improve laminar flow, mitigate water hammer, shaking pipes, splashing, enhance pump performance and flow meter measurement.

SENTRY BENEFITS:

  • Whether a piston, plunger, air diaphragm, peristaltic, gear, or diaphragm metering pump, a SENTRY Pulsation Dampener placed at the pump's discharge will produce a near steady fluid flow up to 99% pulsation and vibration free
  • Protects pipes, valves, fittings, meters, and in-line instrumentation from destructive pulsations, surges, cavitation, thermal expansion, and water hammer
  • Creates steady and continuous flow when dosing, blending or proportioning additives
  • Ensures accuracy, longevity, and repeatability of in-line meters
  • Enables uniform application of material in spraying and coating systems
  • Reduces product agitation, foaming, splashing and degradation of product
  • Provides liquid energy storage for emergency valve closure and other equipment shutdown
  • Reduces overall energy cost with continuous flow, rather than start/ stop flow
  • Operates as a reservoir for make-up fluid
