Pulsation Dampener - AcuFlow Metering Pumps
In some, applications pulsation is a problem, typically with most metering pumps. A Pulsation dampener helps remove a high degree of pulsing and surging in the line. They only work if installed properly, in the right order in the line, and with the appropriate pressure bladder to offset the incoming pulsing. It is important that the directions supplied by the manufacturer regarding the recommended set pressure and location of the dampener be adhered to.
