2 Safety
10 of 76 RPH

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. (⇨ Section 2.10.2 Page 11)
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 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

T1 Maximum 400 °C2)
T2 280 °C
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, 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,
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 6.2.3.1 Page 37) refer to water and water-
like fluids handled. Longer operating periods with these fluids and at the flow rates
indicated will not cause an additional increase in the temperatures at the pump
surface. However, if the physical properties of the fluids handled differ from those of
water, it is essential to check whether additional heat build-up may occur and if the
minimum flow rate must therefore be increased. The calculation formula in
(⇨ Section 6.2.3.1 Page 37) can be used to check whether additional heat build-up
may lead to a dangerous temperature increase at the pump surface.

Bearings used
Design
4 Description of the Pump (Set)
18 of 76 RPH

The fluid enters the pump axially via the suction nozzle (6) and is accelerated
outward by the rotating impeller (7). In the flow passage of the pump casing the
kinetic energy of the fluid is converted into pressure energy. The fluid is pumped to
the discharge nozzle (2), where it leaves the pump. The clearance gap (1) prevents
any fluid from flowing back from the pump casing into the suction nozzle. At the
rear side of the impeller, the shaft (4) enters the hydraulic system via the casing cover
(3). The shaft passage through the cover is sealed to atmosphere with a shaft seal (8).
The shaft runs in rolling element bearings (9 and 10), which are supported by a
bearing bracket (5) connected to the casing cover.
The pump is sealed by a standardised mechanical seal.
