A decontamination facility that pumps acids through a series of 15° spray nozzles to rinse radiation from contaminated metals has experienced problems with the pulsating action of reciprocating pumps causing uneven spray in the rinse tanks. A Sentry 1 Pulsation Dampener was installed at each pump discharge manifold to eliminate the surging flow of the pumps and ensure complete coverage and thorough cleaning. Since installation, even flow ensures the metal product is completely rinsed of radiation. Blacoh Fluid Control 601 Columbia Ave., Suite D Riverside, CA, 92507
