A new series of active pulsation dampeners

| By Chemical Engineering



The new DT series of active pulsation dampeners (photo) is totally redesigned, and has more features and benefits than its predecessor PD. The active pulsation dampener is said to be the most efficient way to remove pressure variations on the discharge of a pump. The dampener works actively with compressed air and a diaphragm, automatically setting the correct pressure to minimize the pulsations. When the liquid pressure falls in the piping system, the dampener supplies extra pressure to the discharge between the pump strokes by displacing liquid by means of diaphragm movement. This pumping action created by the dampener decreases the pressure variations and pulsations. — Tapflo AB, Kungälv, Sweden
