Heavy Duty Closed Spring Isolators

Heavy Duty Closed Spring Isolators

This unique range of Closed Spring Isolators uses an integral rubber end fixing of the spring which sets them apart from all other designs. Loose springs and plates are now history and high frequency and noise attenuation is provided with stable mounting. Originally designed for use for Isolation of heavy equipment the Closed Spring Isolators are now widely used to isolate vibration from every conceivable type of rotating and reciprocating machine. Some examples being big Cooling Towers, Heavy Centrifugal Fans, Heavy Condensing Units, Pumps, Generating Sets, Chillers etc. These Closed Spring Isolators are cost effective and are a much cheaper option compared to our Spring and Viscous Dampers.

Design Features

  • Load Range from 500 – 10500 kg per isolator
  • Unique expanding rubber and fixing of spring which also provides high frequency attenuation.
  • Colour coded springs with 50% overload capacity.
  • Can be bolted to supporting structure or free standing on 5mm thick rubber pad.
  • Reduces Vibration, shock and structure borne noise transmission
  • Load Ranges from 50 to 8,000 lbs.
  • Heavy duty welded steel housings
  • Powder Coated Springs & Body.

Vibration isolators shall be free standing, unhoused, laterally stabile steel springs. Springs shall have a lateral stiffness greater than 1.0 times the rated vertical stiffness and shall be designed to provide a minimum 50% overload capacity.

Springs shall be assembled or welded between top and bottom load plates. The upper load plate shall be provided with steel leveling bolts, lock nut and washer for attachment to the supported equipment. The lower load plate shall incorporate a non-skid noise isolation pad and shall have provisions for bolting the isolator to the supporting structure, as required.

Springs shall be selected to provide operating static deflections shown on the Vibration Isolation Schedule or as otherwise indicated on the project documents. Springs shall be color coded or otherwise identified to indicate load capacity.

Spring Vibration Isolators for floor-mounted equipment shall be Model EFCSI as manufactured by Kanwal Industrial Corporation (Easyflex).
