The indicated noise levels correspond to the standard pump, with maximum impeller and shrouded motor,
running at approximately 2900 rpm, at the point of the best efficiency and with a motor with sufficient power.
These values were taken at a distance of 1 m from the pump and at a height of 1,6 m above the floor level.
The measurements were carried out according to the standard EN 12639 / ISO 3746 Grade 3 with a tolerance
of ±3 dB(A).
