The fully mechanical pulsation damper, low-pressure version, has an air spring bellows which absorbs the medium. The back pressure is generated by a package of maintenance-free and very low-wear elastomer springs.
All functions are visible. There are no invisible elements such as diaphragms or bubbles which have to be periodically checked and refilled, which requires expensive testing and filling equipment and pressure bottles.
Low pressure version up to approx. 7 bar operating pressure.
Medium: water
Int.pat.pend.

The fully mechanical pulsation damper, high-pressure version, works with the deformation of O-rings. The stroke can be varied by any number of elements connected in series. The back pressure is also generated here by one or more elastomer springs, which are essentially maintenance-free and very low-wear.
High pressure version up to approx. 60 bar operating pressure.
Medium: water
Int.pat.pend.

Here the principle of O-ring deformation is clearly visible, on which the high-pressure pulsation damper is based. Rubber has the property of tolerating deformation at any frequency and load number (comparison: flexing of a car tyre!)
