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 Pulsation Dampeners & Surge Suppressors 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 Pulsation Dampeners & Surge Suppressors Features:

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

  • Simple, reliable design and quick installation

  • Easy in-line maintenance

  • Pressure ranges up to 4000 psi (276 bar) available from stock

  • Temperature ranges from -60°F to +400°F (-51°C to +205°C) available from stock

  • Custom models available up to 100 gallons (378.5L) and 25,000 psi (1724 bar)

  • Bodies available in a full range of chemically resistant materials

  • Bladders available for even the most corrosive applications
