2 Safety
11 of 78
Etanorm-R
1222.8/13-EN
▪When taking the pump set out of service always adhere to the procedure
described in the manual. (ðSection6.1.7,Page39) (ðSection6.3,Page42)
▪Decontaminate pumps which handle fluids posing a health hazard.
(ðSection7.3,Page51)
▪As soon as the work has been completed, re-install and re-activate any safety-
relevant devices and protective devices. Before returning the product to service,
observe all instructions on commissioning. (ðSection6.1,Page34)
2.8 Unauthorised modes of operation
Never operate the pump (set) outside the limits stated in the data sheet and in this
manual.
The warranty relating to the operating reliability and safety of the supplied pump
(set) is only valid if the equipment is used in accordance with its intended use.
(ðSection2.2,Page9)
2.9 Explosion protection
!DANGER
Always observe the information on explosion protection given in this section when
operating the product in potentially explosive atmospheres.
Only pumps/pump sets marked as explosion-proof and identified as such in the data
sheet may be used in potentially explosive atmospheres.
Special conditions apply to the operation of explosion-proof pump sets to EU
Directive 2014/34/EU (ATEX).
Especially adhere to the sections in this manual marked with the Ex symbol and the
following sections, (ðSection2.9.1,Page11) to (ðSection2.9.4,Page12)
The explosion-proof status is only assured if the product is used in accordance with its
intended use.
Never operate the product outside the limits stated in the data sheet and on the
name plate.
Prevent impermissible modes of operation at all times.
2.9.1 Marking
Pump The marking on the pump refers to the pump part only.
Example of such marking:
II 2G Ex h IIC T5-T1 Gb
Refer to the Temperature limits table for the maximum temperatures permitted for
the individual pump variants. (ðSection2.9.2,Page11)
The pump complies with the requirements of type of protection constructional safety
"c" to ISO80079-37.
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.
2.9.2 Temperature limits
In normal pump operation, the highest temperatures are to be expected at 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 (ðTable4) lists the temperature classes and the resulting maximum
permissible fluid temperatures. The values shown correspond to the theoretical
limits. They include only a general safety margin for the mechanical seal. For single
mechanical seals, the safety margin required for specific operating conditions and
mechanical seal designs may be substantially higher. If operating conditions differ

2 Safety
12 of 78 Etanorm-R
1222.8/13-EN
from those stated on the data sheet, or if different mechanical seals are used, the
actual safety margin required needs to be determined individually. If in doubt please
contact the manufacturer.
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 ISO80079-36 Maximum permissible
fluid temperature2)
T1 Temperature limit of the pump
T2 280°C
T3 185°C
T4 120°C
T5 85°C
T6 Only after consultation
with the manufacturer
In the following cases, and if ambient temperatures are higher, contact the
manufacturer.
Temperature class T5 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.
Temperature class T6 If temperature class T6 must be complied with, special measures may be required
with regard to bearing temperature.
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.
2.9.3 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 about monitoring equipment.
2.9.4 Operating limits
The minimum flow rates indicated in (ðSection6.2.3.1,Page41) 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 are different
from water, it is essential to check whether an additional heat build-up may occur
and if the minimum flow rate must therefore be increased. The calculation formula
in (ðSection6.2.3.1,Page41) can be used to check whether additional heat build-
up may lead to a dangerous temperature increase at the pump surface.

2. Flush and clean the pump, particularly if it has been used for handling noxious,
explosive, hot or other hazardous fluids.
3. If the pump has handled fluids whose residues could lead to corrosion damage
in the presence of atmospheric humidity or could ignite upon contact with
oxygen also neutralise the pump and blow through with anhydrous inert gas to
ensure drying.
4. Always complete and enclose a certificate of decontamination when returning
the pump.
Indicate any safety measures and decontamination measures taken.

▪Hydraulic pump efficiency (%) with trimmed impeller: see data sheet
▪Pump performance curves, including efficiency characteristics: see documented
characteristic curve
▪The efficiency of a pump with a trimmed impeller is usually lower than that of a
pump with full impeller diameter. Trimming of the impeller will adapt the pump
to a fixed duty point, leading to reduced energy consumption. The minimum
efficiency index (MEI) is based on the full impeller diameter.
▪Operation of this water pump with variable duty points may be more efficient
and economic when controlled, for example, by the use of a variable speed drive
that matches the pump duty to the system.

Design The pump is designed with an axial fluid inlet and a radial or tangential outlet. The
hydraulic system runs in its own bearings and is connected to the motor by a shaft
coupling.
Function 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 casing to the suction nozzle. At the rear side of
the impeller, the shaft (4) enters the casing 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)
linked with the pump casing and/or casing cover.
Sealing The pump is sealed by a shaft seal (KSB cartridge seal or gland packing).
