WILDEN 70-7373 Aluminum Wilden® Equalizer® Surge Dampener SD Series creates laminar process flow by reducing and/or eliminating pump pulsation. SD Equalizers do this by using the same air supply as the pump to counter the pressure changes within the system. When installed properly using the same air supply as the pump, SD Equalizers equalize the correct air pressure to match variations in liquid flow or discharge pressure. SD Equalizers are also ATEX compliant. Meets ATEX II 2 GD X requirements Lowers system maintenance costs Protects in-line equipment Self-adjusts to varying system pressure
