The WFI Water Hammer Dampener is the high purity altarnative for water hammer, designed for aseptic processes requiring clean-in-place components.

The WFI Water Hammer Dampener is designed for clean-in-place aseptic processes and very suitable for WFI systems. The dampener can be installed very close to the pump to absorb the pulse as much as possible as its source. It needs to be installed vertical.


The Water Hammer Dampener has got a unique inline flow-through sleeve which is designed to create a steady flow with zero dead leg. The sleeve expands at a high pressure and returns to it’s original form afterwards. The sleeve ends connect directly with a tri-clamp without the need for a seperate gasket.
