KSB MegaCPK User Manual

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
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.
An EC manufacturer's declaration is required for the shaft coupling; the shaft
coupling must be marked accordingly.
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, at the shaft seal and in the bearing areas.
The surface temperature at the pump casing corresponds to the temperature of the
fluid handled. If the pump is heated in addition, the operator of the system is
responsible for observing the specified temperature class 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.

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.
If grease lubrication is used, compliance with temperature class T5 is not possible.
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, if there is no data sheet 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,
