“PSD” series are very low frequency and very high Viscous Damping Units fitted with a pre- compression device to facilitate adjustment at site and easy installation/removal.
The Isolator can be pre- compressed to its loaded height before installation using Jacks if required, and held in precompression by the Tie Bars. Once the equipment is installed, pre-compression is released by loosening the Tie-Bars.
Top and/or Bottom Friction pads for obviating the need of anchoring (bolting
Also available for bolting to the floor and/or supported equipment.
PASSIVE ISOLATION of major civil engineering structures such as:
ACTIVE ISOLATION of large size rotating machines with or without inertial block running at speeds down to 350 rpm and developing very high dynamic forces (unbalance, short-circuit, couples) such as
