The principle function of a pulsation damper is to damp out the pulse generated on the delivery stroke by pneumatically operated bellow and diaphragm pumps. When the pump is used in conjunction with a filter (the pulse from the AstiPure™ pump is much lower than that generated by an equivalent diaphragm pump) the pulse on the delivery stroke can cause particles trapped in the filter membrane to be forced through the filter, contaminating the fluid.
The pulsation damper, when placed on the delivery side of the pump with the same fittings and air/nitrogen supply, absorbs up to 80% of the pulsations, regardless of fluid pressure or flow rate, protecting the filter element from damage and significantly reducing particle contamination. These pulsation dampers logically carry on our range of “Ultrapure” contamination free products.
Like the rest of our products (including pumps, fittings and valves) all wetted parts are made of High Purity PFA and PTFE. Other parts are made of high tech plastics such as PVDF and PEEK. There are no metal parts avoiding the risk of corrosion or ionic contamination.
