Pulsation dampeners and surge suppressors

Sentry pulsation dampeners and surge suppressors are essentially hydraulic shock absorbers. They reduce hydraulic shock and create a smooth flow. An example of hydraulic shock is water hammer in pipes.

Sentry pulsation dampeners and surge suppressors are manufactured for all types of pulsation and surge generated by processing liquids. They are used with all diaphragm pumps, reciprocating pumps, and quick closing or opening valves.

The units protect: pipes and fittings from pulsation and vibration, meters and inline instrumentation from destructive pulsations and surges; filter media from breakdown due to a pulsation flow; and valves from hydraulic shock and pressure surges.

The units prevent: foaming, splashing and degradation of product; ruptured pipes and fittings due to thermal expansion and hydraulic shock; cavitation and the resulting premature failure of the pump, diaphragms, valves, seals, plungers and packing material; premature release of pressure relief valves and disks, and the resulting contamination of the surrounding area.

The units ensure: meter accuracy, longevity and repeatability; uniform application of material in spraying and coating systems, and reduction of material usage and rejected parts; complete suction stroke filling of pump cylinders and diaphragms; steady and continuous flow when dosing, blending or proportioning process additives; and performance of inline mixers with continuous flow of product.

Industries that use Sentry units are: chemical process; pump, paper and textile; water treatment; gas, oil and petrochemical; biotech; paint and coating; food and beverage; and consumer products.
