3.2.5 Emission sound pressure
The sound pressure level depends on the motor used and can vary depending on the design
and load of the progressive cavity pump. The following table only specifies the highest meas-
ured values.
Version Motor Value
Gearbox version, i =16 Commutator motor 71 dB (A) - 79 dB (A)
Gearbox version, i =7 Asynchronous motor <70 dB (A)
Motor flange version Asynchronous motor < 70 dB (A)
Gearbox version, i =16 Air motor 83
–90 dB (A)*
1 / 95 dB (A)* 2
Motor flange version Air motor 89 dB (A)* 1 /78 dB (A)* 3
