active pulsation dampeners...
The active pulsation dampener is the most efficient way to remove pressure variations on the discharge of the pump. The Tapflo pulsation dampener works actively with compressed air and a diaphragm, automatically setting the correct pressure to minimise the pulsations. The pulsation dampener is available for all Tapflo pump sizes and material versions.

How it works
When the liquid pressure falls in the piping system, the pulsation dampener supply 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.
