Wilden Industrial Surge Dampener

Wilden SD Industrial Surge DampenerThe Wilden line of SD surge dampeners effectively suppress pulsation associated with reciprocating pumps, prolonging equipment life and maximizing mean time between failure (MTBF). The dampener self-adjusts to fluctuating inlet pressures, making the installation flexible, versatile and user friendly for a variety of processes. These dampeners are engineered for demanding solids handling applications commonly found where reciprocating pumps excel.


  • A dampener is an efficient tool to reduce water-hammer and protect in-line equipment.
  • They effectiveley dampen up to 70% of discharge pressure fluctuation.
  • SD Industrial Surge Dampeners use many existing Wilden pump parts to help in maintaining a minimum spare parts inventory.
