PDT Series Plastic Pulsation Dampeners for AODD Pumps

All-Flo™ PDT Series Plastic 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.

PDT Series Pulsation Dampeners are available in conductive plastic construction, which is ideally suited for applications that require grounding (lowering the risk of electrostatic charges).
