Wilden releases new surge stainless steel dampeners for its AODD pumps



The new ‘Equalizer’ named surge dampeners are integrated in the Wilden dampener SD Series (ISD). They are offered in a bolted metal option. This dampener helps

  • to minimize vibration and
  • to control pipe hammer
  • to protect the system piping and downstream instrumentation.

Wilden ISD Series dampeners are installed at the pump’s discharge and have been specifically engineered to reduce fluid pressure and flow fluctuations for a smoother discharge flow. This function not only protects system equipment, but also helps extend the life, decrease the noise and increase the efficiency of Wilden air-operated double-diaphragm (AODD) pumps.

The new ISD Series stainless steel metal dampeners are available in 25 mm (1″), 38 mm (1-1/2″) and 51 mm (2″) sizes. The bolted-construction design and PTFE, Buna backed, integral piston diaphragms offer maximum process fluid containment. This makes them an ideal solution for a wide range of applications, including, but not limited to, oil and gas, paint and coatings, and chemical.
