Temperature class as per EN 13463-1 Maximum permissible fluid
temperature
T3 185 °C
T4 120 °C
T5 85 °C
T6 Only after consultation
with the manufacturer
Based on an ambient temperature of 40 °C and proper maintenance and operation,
compliance with temperature class T5 is warranted in the area of the rolling element
bearings. If the ambient temperature exceeds 40 °C, contact the manufacturer.
A special design is required to comply with the requirements of temperature class T6
in the bearing area.
Misuse, malfunctions or non-compliance with the instructions may result in
substantially higher temperatures.
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 (⇨ Section 6.2.3 Page 44) 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 if 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 44) can be used to check if an additional heat build-up may lead
to a hazardous temperature increase at the pump surface.
