Typical Isolator Schedule Filled In
The information for the vibration isolation specification columns is found in the Specification Selection Guide. You need only reference the type of equipment and fill in the appropriate specification letters and deflections based on the floor span in the equipment’s location.
In the given example we are assuming that the floor spans are 30 ft.(9m) at all locations. In your application, use the proper floor span tabulation. You will note pump No. 5 has no isolation as it is in the basement under the garage where any transmitted vibration would annoy no one. Fire pumps (No. 6) are seldom isolated.
In preparing your specification this way you have an opportunity to consider every piece of equipment, and there is very little possibility of your overlooking something in the rush of getting a job completed.
