Griffco Valve has introduced new pulsation dampeners that offer high reliability, with sizes ranging from 6.0 to 125.0 cubic inches and a dampening effect of +2.5%.
An interactive pulsation dampener sizing calculator on the company’s website enables buyers and specifiers to select the correct size unit based on their volume per stroke, mean system pressure, type of pump, type of gas, and desired dampening effect.
The new Griffco pulsation dampeners have maximum pressure ratings of 250 psi (17 bar) for metallic models and 150 psi (10 bar) for plastic models operating at up to 70°F (21°C). Connection sizes include 1/2”, 3/4”, and 1” (DN 15, DN 20, and DN 25) in NPT, BSPT, Socket, Union, or Flange connections. Gauge port sizes are offered in 1/8”, 1/4”, and 1/2” (DN 6, DN 10, and DN 15). Manufactured in the USA, they feature a choice of molded Noryl®, PP, PVDF, or 316 Stainless Steel construction.
