BLACOH is the industry standard for dampening the pulsation created by positive displacement pumps. They have been in business for more than 30 years, providing smooth fluid flows for pumping systems all over the world. BLACOH stands alone as the industry leader and foremost expert in the manufacture of fluid control products for all facets of municipal and industrial process industries, and virtually every application, from the harshest chemicals to the most delicate cosmetics.
SENTRY Pulsation Dampeners, Surge Suppressors and Inlet Stabilizers remove hydraulic shock and vibration, enhancing all-around performance and reliability of fluid flow applications. All SENTRY dampeners manufactured by BLACOH use pressure bodies made in the USA to ensure quality. Prior to shipment, each and every dampener is factory tested at design pressure or higher to assure proper function and leak-free operation.
All Pumps has been importing, servicing and supplying BLACOH Products in Australia for 15 years and support the full BLACOH range of pumps and spare parts.
Positive displacement pumps create destructive pulsation and hydraulic shock due to the reciprocating nature of their stroking action, potentially damaging piping and system components. SENTRY Pulsation Dampeners and Surge Suppressors remove virtually all system shock, enhancing the performance and reliability of fluid flow in municipal, industrial, sanitary and chemical transfer applications.
Positive displacement pumps contain an inlet valve that alternately opens and closes, creating an acceleration and deceleration of fluid into the pump.
SENTRY Inlet Stabilizers minimise these pressure fluctuations and acceleration head losses by preventing fluid column separation at the pump's inlet. The patented “J” Model air control allows for pressure or vacuum settings and is adjustable for suction lift or positive inlet pump conditions. (US Patent 6,089,837)
SENTRY Pulsation Dampeners, Surge Suppressors and Inlet Stabilizers come in a full range of chemically resistant materials for even the most corrosive applications. The simple, reliable design allows for quick installation and easy in-line maintenance. All SENTRY housings are made in the USA and each unit is tested at design pressure or higher to assure proper function and leak-free operation.
Without proper protection, process fluids regularly contaminate and damage in-line instrumentation. The strength and durability of SENTINEL Diaphragm Seals protect and isolate all forms of system instrumentation from the hazards of corrosive process fluids.
SENTINEL Diaphragm Seals are easily installed, come in a variety of chemically resistant materials, and work in both pressure and vacuum conditions.
SENTINEL diaphragm pressure relief valves are designed to continuously regulate fluid flow to protect pumping systems from over- pressure damage caused by defective equipment or a blockage in the pump system line.
SENTINEL diaphragm back pressure valves enhance system performance by applying a continuous back pressure to the system pump. Eliminating fluctuations in downstream pressure prevents siphoning and eliminates varying dosage rates, and the continuous back pressure ensures proper check valve operation in metering pumps when system pressure is too low.
Diaphragm failure in air operated diaphragm pumps allows process fluid to escape through the pump's air exhaust port. Unmonitored, the spill can result in significant expense to your company due to lost product, hazardous material cleanup, EPA reporting and system downtime.
SPILLSTOP's patented design prevents hazardous and costly spills by capturing the expelled process fluid and automatically shutting down the pump. (US Patent 5,501,577)
