All-Flo™ PDT Series and PDM Series Pulsation Dampeners are recommended accessory products that help expand the application range and augment the performance of All-Flo Air-Operated Double-Diaphragm (AODD) Pumps. Installed at the pump’s discharge, All-Flo pulsation dampeners reduce fluid pressure and flow fluctuations to provide a smoother discharge flow. This function is critical in applications that need to minimize system vibration in order to protect and enhance the accuracy of downstream instrumentation. It also extends equipment life by reducing the load on the pump.
