Mechanical Vibration Isolation Equipment

Spring-Flex Mountings

B/C/D Series
Up to 2.00" Deflection - 60 - 26,000lbs Load Range

B/C/D Series Spring-Flex mountings are extremely versatile vibration control isolators for use under engine gensets, industrial machinery, pumps, compressors, chillers, fans, and other HVAC equipment. The B/C/D Series are offered in several standard versions that provide a wide range of installation options - internal or external level adjustments, elastomeric snubbing for side loads, steel or cast aluminum housings, and many mounting choices.

The B/C/D Series feature telescoping housings with up to 20 springs, providing superior isolation capabilities over a variety of applications. The series include resilient inserts that act as upper and lower housing guides and prevent metal-to-metal contact. Replaceable elastomeric acoustical non-skid pads are attached to the bottom of the housings.

The BP/CP/DP types offer a centrally located positioning pin and internal adjustments that permit installation anywhere regardless of accessibility or the location of bolt holes in the equipment. The BT/CT/DT types add non-skid, ribbed elastomeric pads bonded to the top and bottom of the housings for increased stability under equipment that does not require bolting. 

The housings are made of cast steel or welded steel for optimum strength and durability. All hardware is stainless steel or zinc-plated. Lightweight cast aluminum housings with electroplated hardware and springs are available for applications where mounting weights are a concern. The all-steel springs are color-coded for easy identification and offer a powder-coated finish for improved corrosion resistance.

Floor Mounted Isolators II

Series: CT
Load Range: 15 - 25,000 lbs.

Steel-housed open spring isolators for 1” to 5” deflection.

Spring-Flex Mountings

A Series
Up to 5.00" Deflection - 60 - 3680lb Load Range

A Series Spring-Flex mountings are designed to isolate low frequency vibrations in air handling units, fans, chillers, and other HVAC equipment. The A Series are recommended for use directly under most HVAC equipment and in conjunction with structural steel bases and concrete inertia blocks.

The A Series are freestanding spring mountings that are laterally stable. The coils are designed with an excellent ratio between the coil outer diameter and the operating height – ensuring lateral stability. In all the A Series designs, this ratio is a minimum of 0.80” and many have a 1:1 ratio. The coils are built to low operating stresses – providing long mounting life.

The A Series also feature weldless construction. The spring coils are not welded to steel plates that could introduce excessive stress at the weld areas and result in the failure of the springs. Instead, the A Series are assembled to elastomeric cups or to steel plate bases – providing durability and flexibility. The series also include a built-in leveling device for simplified installation. The products incorporate a color-coded steel spring for ease of identification and inspection in the field.
