Pulsation Dampeners and Surge Suppressors – Fluid Control

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
