Blacoh UniversityBlacoh U


Blacoh recently introduced a unique on line learning tool for both customers and distributors dedicated to the applcation of knowledge relating to fluid control process. The University tools include several videos on the application of pulsation dampeners,and technical publications. The online training allows customers to record their training for Professional Development Hours. There is an excellent presentation on water hammer as well as maintenance videos.

Water Hammer Application

A quick closing valve can create dangerous pressure surges during operation. When fluid velocity is stopped, it is transformed into pressure energy, causing a pressure spike up to six times greater than operating pressure - valves are destroyed, piping is ruptured, and sensitive instrumentation is damaged. A SENTRY SURGE SUPPRESSOR, placed upstream as close to the valve as possible, will absorb dangerous pressure spikes.

High Pressure Pulsation Dampener

Blacoh has a line of high pressure pulsation dampeners in 316L stainless steel for system using reciprocating positive displacement pumps. With pressure ratings up to 13,500 psig and temperature ranges from -60F to 225F,these high pressure models are ideally suited for metering and dosing aplications typical in the oil and gas industry. They are available in sizes up to 24 cubic inches, depending on th pressure requirements, with Viton, Buna or EPDM bladders.
