Pump noise emission < 70 dB(A)
• Measurements were carried out on dry-installed pumps in a
closed system.
• Sound power measurements were carried out according to
ISO 3743.
• Sound power was calculated at a distance of 1 metre
according to ISO 11203.
The sound pressure level of the pump is lower than the limiting
values stated in the EC Council directive 2006/42/EC relating to
machinery.
