Etaprime L
Never operate the pump set outside the limits stated in the data sheet and on the
name plate.
Prevent impermissible modes of operation at all times.
2.10.1 Marking
Pump
The marking on the pump refers to the pump part only.
Example of such marking: II 2 G c TX
Refer to the Temperature Limits table for the temperatures permitted for the
individual pump variants.
Shaft coupling
An EC manufacturer's declaration is required for the shaft coupling; the shaft
coupling must be marked accordingly.
Motor
The motor must be considered separately.
2.10.2 Temperature limits
In normal pump operation, the highest temperatures are to be expected on the
surface of the pump casing and at the shaft seal.
The surface temperature at the pump casing corresponds to the temperature of the
fluid handled. If the pump is heated, the operator of the system is responsible for
observing the specified temperature classes and fluid temperature (operating
temperature).
The table below lists the temperature classes and the resulting theoretical
temperature limits of the fluid handled. (A possible temperature rise in the shaft seal
area has already been taken into account).
The temperature class specifies the maximum permissible temperature at the surface
of the pump set during operation. For the permissible operating temperature of the
pump in question refer to the data sheet.
Table 4: Temperature limits
Temperature class to EN 13463-1 Maximum permissible fluid
temperature
T1 Temperature limit of the pump
T2 280 ℃
T3 185 ℃
T4 120 ℃
T5 85
℃
T6 Only after consultation
with the manufacturer
In the following cases, and if ambient temperatures are higher, contact the
manufacturer.
Temperature class T5
Compliance with temperature class T5 is warranted for the area of the rolling
element bearings based on an ambient temperature of 40°C, assuming that the
pump set is properly serviced and operated and that the surfaces in the bearing area
are freely exposed to the atmosphere.
Temperature class T6
If temperature class T6 has to be complied with, special measures may have to be
taken with regard to the bearing temperatures.
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.
Motor supplied by the
operator
If a pump is supplied without motor (as part of a pool of pumps), the motor specified
in the pump data sheet must meet the following conditions:
▪ The permissible temperature limits on the motor flange and motor shaft must be
higher than the temperatures generated by the pump.
▪ Contact the manufacturer for the actual pump temperatures.
