Process control engineers and operators face many challenges to keep pumping systems running efficiently and reliably. For users of positive displacement (PD) or PD-style pumps, the issues of addressing damaging pulsations caused by the stroke of the pump are all too common and unavoidable. These pulsations will often violently rattle or shake piping, causing noise, premature wear and potentially a complete break in the pipe itself or damage to valuable components in the flow path downstream of the pump. Traditionally, the solution has been to install a pulsation dampener on the discharge side of the pump.
