3.3.4 How to reduce noise in the installation
Vibrations from the pump may be transferred to the
surrounding structure and create noise in the
20-1000 Hz spectrum, also called the bass
spectrum.
Correct installation using a vibration-damping rubber
pad, flexible hoses and correctly placed pipe
hangers for rigid pipes can reduce the noise
experienced by up to 50 %. See fig. 4.
Place pipe hangers for the rigid pipes close to the
connection of the flexible hose.
