The media is pumped through the pulsation dampener, and passes a pneumatically controlled diaphragm. The diaphragm counteracts the pulsations, that are inherent in the design of a pneumatic double diaphragm pump, lowering them with up to 90%.
-The Tapflo series of pulsation dampeners are now supplied with an upgraded design, offering increased reliability, higher resistance against chemical attacks and with a wide range of installation designs, explains Hakan Ekstrand at Tapflo Group.
Industrial and sanitary executions are offered, in non-metallic materials PE and PTFE, as well as in acid proof steel AISI 316. An unique design is utilized in the PTFE dampeners, in order to avoid the commonly seen material expansion, when using PTFE.
Tapflo´s new series of pulsation dampeners, has been performance tested at ”Statens Provningsanstalt”
-We now also offers an installation, where the Tapflo pulsation dampener and the Tapflo Guardian pump control system are combined in a single unit. This compact unit gives the pump user not only a smooth flow, but also a system that continuously monitor the condition of the diaphragms, stopping the pump in case of a failure, ends Hakan Ekstrand.
What is an active pulsation dampener?
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 minimize 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.
