2.3 Noise Emissions
KRVS noise level is indicated in the bottom table as Sound Pressure Level measured in free field and at 1 m distance from KRVS following
the norm ISO 3746 (tolerance +/- 2 dB(A))
Noise level radiated from the surface of the pump is indicated in the table 5

Warning: Too high intake liquid
flow may seriously damage the pump
Note: For special application and for suction of bigger quantity of intake liquid please consult us.
NOTE: The value indicated in the table is referred to the pump only measured in a
free field, the value
measured in the installation site can be different by the noise radiated by the piping and by the
reverberation characteristic of the ambient
