2.9.4 Operating limits
The minimum flows indicated in (
Section 6.2.3.1, Page 40) refer to water and
water-like fluids handled. Longer operating periods with these fluids and at the flow
rates indicated will not cause an additional increase in the temperatures at the pump
surface. However, if the physical properties of the fluids handled are different from
water, it is essential to check whether an additional heat build-up may occur and if
the minimum flow rate must therefore be increased. The calculation formula in
(
Section 6.2.3.1, Page 40) can be used to check whether additional heat build-up
may lead to a dangerous temperature increase at the pump surface.
2.10 Magnetic coupling
DANGER
Strong magnetic field in the area of the magnetic coupling or the individual
magnets
Danger of death for persons with pacemaker!
Interference with magnetic data carriers, electronic devices, components and
instruments!
Uncontrolled magnetic attraction forces between magnet-equipped components,
tools or similar!
▷
Keep a safety distance of at least 0.3 m.
Distance to assembled pumps:
The safety distance refers to magnet-equipped rotors not yet installed in pumps and
to magnets which have not been fitted.
In installed condition the magnetic field is fully shielded so that an assembled pump
does not pose a hazard as a result of magnetic fields (even to persons with
pacemaker), neither during standstill nor during operation.
