MS Series Isolators, combine our open spring mountings within a rugged welded seismically rated steel housing. To minimize, the code required seismic loads on the isolated equipment, the housing is designed to limit equipment motion to ¼” in horizontal directions due to wind or seismic loads. The MS style isolator has internal spring adjustment. The top housing incorporates seismic restraint bolts that pass through the lower housing and are protected in all directions by an elastomeric bushing. Combined, the restraint bolts and bushings act as the internal snubbing devices for the isolator. To achieve accurate installation heights, The VMC Group has incorporated an installation spacer between the lower and upper housing.

After the equipment is installed and the isolators are properly adjusted, there will be no difference between the installed and operating heights. Mechanical equipment can be positively attached to the top housing by utilizing the pre-drilled bolt holes or by welding directly to the housing. Low frequency T-Series steel springs are located within the housing and are seated in an elastomeric acoustical cup that provides high frequency attenuation and eliminates metal-to-metal contact.

The spring and cup design allows for easy replacement or changing of springs when required and all springs are color-coded for ease of identification in the field. The lower housing incorporates an oversized base plate that spreads the anchor bolt over a wider area – this is specifically designed to increase seismic restraint capability. As an additional benefit, ease of installation is also achieved by allowing easy access to the anchor bolts. These isolators are designed for installations in either concrete or steel and the base plates are pre-drilled with mounting holes to accommodate attachment to MS Series Isolators. MS Isolators are available with 1″ through 5″ deflection springs. Each style of mount has a load range of 50 lbs. to 68,000 lbs.
