If the pump is to be operated at a higher temperature, the data sheet is missing or if
the pump is part of a pool of pumps, contact KSB for the maximum permissible
operating temperature.
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 (
Section 6.2.3 Page 35) refer to water and water-
like fluids. Longer operating periods with these fluids and at the flow rates indicated
will not cause an additional increase in the temperatures on 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 Page 35) can be used to check whether an additional heat build-up
may lead to a hazardous temperature increase at the pump surface.
