BA series pumps
Data 1401
2.2
2.3 Sound level
Because the pump, with or without the drive unit, is usually part of a complete installation, the final
configuration is usually not known at the time of delivery. The sound level also depends in part on the
sound production of the other components in the installation.
BBA Pumps conducts random sound measurements on a complete installation. The measurements are
taken at a distance of 1 m (3.3 ft) and a height of 1.6 m (5.2 ft). The average of the measured values is
less than 80 dB(A).
These measurements do not take the drive system or piping into consideration. It is assumed, however,
that the pump is set up/installed in accordance with the instructions and is operating without cavitation.
