Blacoh Sentry Pulsation & Surge Control

Sentry Hydraulic Surge Suppressors

SENTRY Surge Suppressors use a compressed gas separated by a bladder from process fluid to suppress hydraulic surge or "water hammer" created by quick-closing valves, back surge, and pump startup and shutdown. Without suppression, shock waves created will continue to oscillate back and forth until dissipated by friction or system component failure.

Benefits of Surge Suppression:
  • 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 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.
