Never operate the pump set outside the limits stated in the data sheet and on thename 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 TXRefer to the Temperature Limits table for the temperatures permitted for theindividual pump variants. (⇨ Section 2.10.2 Page 11)
An EC manufacturer's declaration is required for the shaft coupling; the shaftcoupling must be marked accordingly.
The motor has its own marking. The marking is maintained on the condition that thetemperatures the pump causes to develop at the motor flange and motor shaft arepermitted by the motor manufacturer.The motors fitted by KSB on pumps with ATEX certification meet this condition.
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 thefluid handled. If the pump is heated, the operator of the system is responsible forobserving the specified temperature classes and fluid temperature (operatingtemperature).The table below lists the temperature classes and the resulting theoreticaltemperature limits of the fluid handled. (A possible temperature rise in the shaft sealarea has already been taken into account).
The temperature class specifies the maximum permissible temperature at the surfaceof the pump set during operation. For the permissible operating temperature of thepump in question refer to the data sheet.

If the pump is to be operated at a higher temperature, the data sheet is missing or ifthe pump is part of a pool of pumps, contact KSB for the maximum permissibleoperating temperature.
If a pump is supplied without motor (as part of a pool of pumps), the motor specifiedin the pump data sheet must meet the following conditions:
▪ The permissible temperature limits at the motor flange and motor shaft must behigher than the temperatures generated by the pump.
▪ Contact the manufacturer for the actual pump temperatures.
2.10.3 Monitoring equipment
The pump (set) must only be operated within the limits specified in the data sheetand 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 setfunctions properly.

2.10.4 Operating limits
The minimum flows indicated in (⇨ Section 6.2.3.1 Page 29) refer to water and water-
like fluids. Longer operating periods with these fluids and at the flow rates indicatedwill 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, itis essential to check whether an additional heat build-up may occur and if theminimum flow rate must therefore be increased. The calculation formula in(⇨ Section
6.2.3.1 Page 29) can be used to check whether an additional heat build-up may leadto a hazardous temperature increase at the pump surface.

The fluid enters the pump via the suction nozzle (6) and is accelerated outward bythe rotating impeller (7). In the flow passage of the pump casing the kinetic energyof the fluid is converted into pressure energy. The fluid is pumped to the dischargenozzle (2), where it leaves the pump. The clearance gap (1) prevents any fluid fromflowing back from the casing to the suction nozzle. The hydraulic system is closedwith a casing cover (3) at the rear side of the impeller; the stub shaft (10) enters thecasing via the casing cover (3). The shaft passage through the cover is sealed to the
atmosphere with a dynamic shaft seal (9). The stub shaft runs in a plain bearing (8)and the motor's rolling element bearings. The motor housing (5) is linked with thepump casing and the casing cover via the drive lantern (4).
The pump is sealed by a standardised mechanical seal.
