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 symbol opposite and
the following sections, (ðSection2.9.1,Page10) to (ðSection2.9.4,Page11)
The explosion-proof status of the pump set is only assured if the pump set is used in
accordance with its intended use.
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.
2.9.1 Marking
Pump The marking on the pump refers to the pump part only.
Example of such marking:
II 2 G c TX (EN 13463-1) or II 2G Ex h IIC T5-T1 Gb (ISO 80079-36)
Refer to the individual Temperature Limits table for the temperatures permitted for
the individual pump variants. (ðSection2.9.2,Page10)
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 has its own marking. The marking is maintained on the condition that the
temperatures the pump causes to develop at the motor flange and motor shaft are
permitted by the motor manufacturer.
The motors used by KSB on pumps with ATEX certification meet this condition.
2.9.2 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 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 potential temperature rise in the shaft seal
area has been taken into account).

2 Safety
11 of 64
Etaline
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 or ISO
80079-36
Maximum permissible
fluid temperature
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
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 at the motor flange and motor shaft must be
higher than the temperatures generated by the pump.
▪Contact the manufacturer for the actual pump temperatures.
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 flows indicated in (ðSection6.2.3.1,Page33) 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33) can be used to check whether additional heat build-up
may lead to a dangerous temperature increase at the pump surface.

4.2 Product Information as per Regulation No. 547/2012 (for water pumps
with a maximum shaft power of 150kW) implementing "Ecodesign"
Directive 2009/125/EC
▪Minimum efficiency index: see name plate, key to name plate
▪The benchmark for the most efficient water pumps is MEI ≥ 0.70.
▪Year of construction: see name plate, key to name plate
▪Manufacturer’s name or trade mark, commercial registration number and place
of manufacture: see data sheet or order documentation
▪Product’s type and size identificator: see name plate, key to name plate
▪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 a radial fluid inlet (suction nozzle) and a radial outlet
(discharge nozzle) arranged on the same axis. The hydraulic system is rigidly
connected to the motor by a shaft coupling.
Function The fluid enters the pump 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 (9) enters the hydraulic system through 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 (10 and 11), which are supported by a motor housing
(5) linked with the pump casing and/or casing cover via the drive lantern (4).
Sealing The pump is sealed by a standardised mechanical seal.
