The Pulsation Dampener from IMI is designed to minimise pressure pulsations downstream of positive displacement pumps. Installed directly at the pump discharge, it reduces system oscillations by up to 70%, improving equipment reliability and performance. With a spherical shell and efficient internal flow design, it creates a rotating fluid mass that naturally dampens fluctuations. The unit is maintenance-free, containing no moving or replaceable parts. Constructed from carbon or stainless steel and suitable for a wide temperature range, the Pulsation Dampener offers easy installation with pre-labelled nozzles and multiple connection options, making it ideal for demanding industrial systems.
