4.7 Noise characteristics
The pressure booster system is available with different numbers and sizes of pumps.
For the noise characteristics refer to the operating manual of the pump set. To
calculate the expected total sound pressure level, add a defined value to the
individual pump set’s expected sound pressure level.
Table9: Values for calculating the total expected sound pressure level
Number of pump sets Value
dB(A)
2 + 3
3 + 4,5
4 + 6
5 + 7
6 + 7,5
Example Pressure booster system with 4 pump sets (value: + 6dB(A))
Single pump = 48dB(A)
48dB(A) + 6dB(A) = 54dB(A)
The expected total sound pressure level of 54dB(A) may develop when all 4 pump
sets are running under full-load conditions.
