Plast-O-Matic Valves, Inc. Pulsation Dampener and Suppressor PDS

PDS is available in three capacities/sizes: 10 cubic inch capacity with a 1" NPT process connection, 50 cubic inch capacity with a 2" NPT process connection, and 180 cubic inch capacity with a 3" NPT process connection. Body materials are choice of Geon PVC, CPVC, Natural Polypropylene, or Kynar PVDF. Inlet screen and dome top match selected body material. Bladder material is EPDM or FKM. Air inlet valve and gauge isolation valve (non-wetted) are brass. Fasteners are stainless steel. Pulsation Dampener and Surge Suppressor will steady a pulsing flow caused by diaphragm pumps, piston pumps, peristaltic pumps and other quick flow interrupting equipment. When used properly, quick pulsating flows will be greatly reduced preventing a number of flow control problems. Series PDS Provides six important functions: • Pulsation Dampener smooths pump flow • Surge Suppressor absorbs shocks and vibrations • Water Hammer Arrestor eliminates dangerous pressure spikes caused by quick closing valves • Inlet Stabilizer enhances pump performance and longevity • Accumulator releases stored fluid during unwanted pressure drops • Expansion Tank protects system from thermal volume increases …available with threaded connections in three capacity sizes and a variety of thermoplastic materials.
