Vibration isolators for equipment & machinery

Vibration isolators spring type DSD

Manufacturer: Getzner Spring Solutions

Design

The Isotop® DSD spring vibro-isolators consist of two plate bases with an internal M10 thread and a cylindrical coil spring (according to the DIN EN 13906-1:2001 norm).

Its elements are protected against corrosion through cataphoretic coating (KTL), which makes them highly resistant to rusting.
Located inside the isolator is a damping core made of a special material called Sylomer-HD, carefully selected to match the spring’s properties. The material retains its elasticity and is highly durable.

Application

Isotop® DSD vibro-isolators are used for the foundation of machines which generate dynamic forces also at low frequencies, such as:

• blocked heating/cooling units,

• compressors,

• rotary machines, engines, turbines,

• portable devices, power generators,

• centrifugal separatos, pumps,

• measuring tables, control boards, scales,

• vibrating tables, conveyors,

• transport of fragile goods.

Information necessary for product selection

• weight of the machine/device,

• number and positioning of the fulcrums,

• positioning of the centre of mass,

• dimensions of the machine/device,

• load direction (vertical, horizontal),

• lowest vibration frequency (No. of rotations or cycles).

• description of the startup process (startup frequency).

 

Advantages 

• freedom of tilting in the vertical direction,

• interchangeability due to the same size and threaded connections,

• the open design of the isolator allows for effortlessly checking the spring’s condition and the distance between its coils,

• the damping core retains its elasticity and is resistant to damage,

• high resistance to corrosion.
