▪ When taking the pump set out of service always adhere to the procedure
described in the manual. (
ð Section 6.3, Page 42)
▪ Decontaminate pumps which handle fluids posing a health hazard.
(
ð Section 7.3, Page 49)
▪ 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. (

Section 6.1, Page 35)
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 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.
Misuse, malfunctions or non-compliance with the instructions may result in
substantially higher temperatures.
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).
