BLACOH Fluid Control, a leading provider of pulsation dampeners and similar products designed to control pump system vibration and hydraulic surge, recently announced the latest in its line of SENTRY XP high pressure pulsation dampeners. The new XPA models in 316L wetted stainless steel feature a redesigned threaded end cap that significantly increases the dampener’s maximum pressure rating with a more rugged, corrosion-resistant sealing component.
The new end cap on XPA models incorporates a large 2.875 – 20 UNF thread that replaces retaining rings on the original XP models. Larger multiple threads allow the necessary grip area and shear allowance to withstand significantly higher maximum allowable working pressures. The original XP models were rated up to 4,000 psi. Now, with the new threaded cap design, XPA models are rated up to 7,500 psi (517 bar) – almost twice the maximum pressure rating of previous models available.
SENTRY XPA dampeners are available in 8, 12 and 24 cubic inch and a variety of pressure ratings with BUNA-N, EPDM and VITON® bladders and standard ½ inch FNPT inlets (ANSI Class flanges available on request). In addition to the new XPA models, BLACOH’s SENTRY XP dampener series includes 12 cubic inch XPX models, also in 316L wetted stainless steel, with pressure ratings up to 13,500 psi (930.8 bar).
BLACOH has been providing fluid flow solutions for pumping systems worldwide since 1976. Their complete line of SENTRY pulsation dampeners, surge suppressors and inlet stabilizers protect pumps and system components from destructive pulsation, pressure surge and hydraulic shock, and act as accumulators to store fluid energy wherever hydraulic fluid is used as a power source. BLACOH products are manufactured in the USA to exacting standards in a variety of sizes, with chemically resistant materials and pressure ratings available to suit virtually every application.
