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
