Engineered Products for Industrial Fluid Control

Blacoh Fluid Control's, SENTRY Pulsation Dampeners, Surge Suppressors, Suction Stabilizers and Thermal Expansion Chambers take the shock out of fluid flow in industrial and chemical pumping applications. SENTRY hydro-pneumatic products are manufactured to the highest quality standards and in the largest variety of chemical resistant materials available. The simplicity of design includes only one moving part, the bladder, a choice of air charging assemblies, and easy in-line maintenance. SENTRY products are engineered to a 4:1 pressure safety margin at ambient temperature and warranted for material and workmanship.

Installed in-line, SENTRY protects pipes, valves, fittings and sensitive equipment from vibration and fatigue, due to the pulsating flows created by reciprocating pumps and prevents "hammer shock" created from quick closing valves. SENTRY can be used on all pump types: piston, diaphragm, peristaltic, metering and air operated double diaphragm pumps. Pumps and components last longer and perform more efficiently, avoiding costly chemical spills, insuring accuracy of in-line meters, and protecting pipe from breakage.
