Proper Sizing
Once it is determined as to what type of vibration dampening device is needed, weight loading is the next
crucial step. As a built in safety measure, take the actual weight of supported pipe or equipment (consider all
accessories - i.e. valves, insulation, brackets, etc...) and multiply by 1.25. Then refer to the sizing chart for the
selected product to determine part number.
Sizing: Divide weight of equipment by points of support to determine load requirement per support.
Example: 240 Lb. (90.7 kg) piece of equipment, 4 support points, take 240 x 1.25 = 300 Lbs. (136.1 kg)
(safety measure), then take 300 ÷ 4 = 75 Lbs. (34.0 kg) Specify appropriate vibration device rated at
75 Lbs. (34.0 kg) for each of the support points.
If weight of equipment is unequally proportionate, select mounts to satisfy the weight distribution.
All dimensions in charts and on drawings are in inches. Dimensions shown in parentheses are in millimeters unless otherwise specified.
