Spring Isolators V403 – V406

All metal isolator of the double-action type, designed for loading in tension and compression. Isolation of exhaust systems, especially on ships. Isolation of various pipes (pressurised air or fluids). Protection of fragile equipment during transportation.

Product Characteristics

All metal isolator of the double-action type, designed for loading in tension and compression. Resilient elements: High tensile steel springs and 18/8 stainless steel cushions. Brass spherical nuts. Housing and other parts in steel.

Protection: Paint

A series of low-frequency isolators operating in both tension and compression.

Natural frequency: 3.5 to 5 Hz.
Amplification factor: < 8.
Temperature range: -90 °C to +300 °C.
Maximum load corresponding to a continuous acceleration of 3 g.

Product Applications

Isolation of exhaust systems, especially on ships. Isolation of various pipes (pressurised air or fluids). Protection of fragile equipment during transportation.

Installation

Attachment points to be made as shown in the cross-selection A-A. The mount may then be easily hooked onto the bracket without removing the nuts. The distance between the cups can be adjusted by turning the sleeve and locking the nut. The isolator must not be tensioned. Dimension “h” must be checked after thermal expansion of the pipe and the locknut locked afterwards. Dimension “h” must be within the ± 3 mm tolerances.
