Vibration dampers

Vibration dampers prevent vibrations being transmitted through the whole structure and creating noise. Installing spring elements in the structure substantially decreases the vibration transference from one part to another. Full insulation is not possible because vibrations are always transferred from one part to another in other ways. The type, shape, hardness and material of the vibration damper can vary, depending on the situation.

Applications of vibration dampers
The product is mainly used in machines and equipment with moving parts that rotate and make backwards and forwards movements. For example: engines, cogeneration, compressors, turbines, generators, pumps and ventilators.

Vibration dampers delivery range
A complete list of the entire programme is too extensive to list here. Please contact us for more specific information or a detailed quotation. If you have a question about a vibration problem, we suggest you collect the following information before contacting us:

Type of machine
Weight of the machine and possibly weight of the frame
Rotational speed or number of turns, etc.
The amount of support points
The kind of floor, for example concrete, wood
The environment
