net.grundfos.comIf you use vibration dampers, install them under the foundation. For pumps with motor size below or equal to 30 kW, you can use vibration dampers as shown in fig. 7. For pumps with motor sizes equal to 37 kW or above, use a Sylomer® plate as shown in fig. 8. Fig. 7 Pump on vibration dampers TM05 9579 4113 hf = Mpump × 1.5 Lf × Bf × δconcrete

pkel015.connect.amazon.auckland.ac.nzviscoelastic polymer compound - the dampers are fixed to some of the diagonal bracing members. Sometimes it is necessary to control vibrations but the use of a polymer is inappropriate - in this case it is necessary to use some other material with good vibration-control properties.

rotorlab.tamu.eduConnection with Dampers Assumed motion conditions: a. Both m1 and m2 are moving to the right , and b. The velocity of m2 is greater than the velocity of m1. Based on this assumed motion, tension is developed in left and center dampers, but compression is developed in the right damper. The tension in damper 1 is , the tension in damper
