3.1.4 Vibration dampening
Elimination of noise and vibrations is best achieved
by means of a concrete foundation, vibration
dampers and expansion joints.
If 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. 21.
For pumps with motor size equal to 37 kW or above,
you can use a Sylomer
®
plate as shown in fig. 22.
