Pump curves
Pump curves are available via the internet on
www.grundfos.com.
The curves are to be considered as a guide. They must not be
used as guarantee curves.
Test curves for the supplied pump are available on request.
It must be ensured that the pump does not operate outside the
recommended operating range during normal operation.
Pump noise emission < 70 dBA
• 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.
