Dampeners & Suppressors

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.

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

SENTRY FEATURES:

  • Sizes available for all positive displacement pumps with discharge sizes from 1/8" (3.18mm) to 6" (152.4mm)
