2.10.3 Monitoring equipment
The pump (set) must only be operated within the limits specified in the data sheet
and on the name plate.
If the system operator cannot warrant compliance with these operating limits,
appropriate monitoring devices must be used.
Check whether monitoring equipment is required to ensure that the pump set
functions properly.
Contact KSB for further information on monitoring equipment.
2.10.4 Operating limits
The minimum flows indicated in
(
ð
Section 6.2.3.1, Page 39)
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 39)
can be used to check whether additional heat build-up
may lead to a dangerous temperature increase at the pump surface.
