PDM Pulsation Dampeners

The All-Flo™ PDM Series Metal Pulsation Dampeners are essential accessories that enhance the performance and expand the application range of All-Flo Air-Operated Double-Diaphragm (AODD) Pumps. When installed at the pump’s discharge, these dampeners minimize fluid pressure and flow fluctuations, ensuring a smoother discharge flow. This is particularly important in applications where reducing system vibration is crucial for protecting and improving the accuracy of downstream instrumentation. Additionally, they extend equipment life by lowering the load on the pump.

Available in bolted metal construction, PDM Series Pulsation Dampeners are suitable for a variety of aggressive applications.

PDT Pulsation Dampeners

The All-Flo™ PDT Series Plastic Pulsation Dampeners are essential accessories designed to enhance the performance and expand the application range of All-Flo Air-Operated Double-Diaphragm (AODD) Pumps. When installed at the pump’s discharge, these dampeners reduce fluid pressure and flow fluctuations, resulting in a smoother discharge flow. This is crucial for applications that require minimized system vibration to protect and improve the accuracy of downstream instrumentation. Additionally, they help prolong equipment life by reducing the load on the pump.

The PDT Series Pulsation Dampeners are made from conductive plastic, making them ideal for applications that necessitate grounding and reduce the risk of electrostatic charges.
