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 and Surge Suppressors remove virtually all hydraulic shock, enhancing all-around performance and reliability of fluid flow in industrial and chemical transfer applications.

• 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

• 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
