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 all hydraulic shock, enhancing all-around performance and reliability of fluid flow in industrial and chemical transfer applications. Now SENTRY pulsation dampeners are available in Australia through H2O Rx / Chemical System Consulting .
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 steady fluid flow, pulsation and vibration free.
SENTRY pulsation dampeners are optimally applied to systems with pressure ranges of up to 27,550kPa and are available in a wide range of sizes for all positive displacement pumps with discharge sizes from 1/8" (3.18mm) to 6" (152.4mm). They are suitable for all climates with temperature ranges from -51°C to +205°C (-60°F to +400°F) available from stock. Additionally SENTRY pulsation dampeners are available in a full range of chemically resistant materials.
