relevant devices and protective devices. Before returning the product to service,
observe all instructions on commissioning. (ðSection6.1,Page47)
2.8 Unauthorised modes of operation
Never operate the pump (set) outside the limits stated in the data sheet and in this
operating manual.
The warranty relating to the operating reliability and safety of the pump (set)
supplied is only valid if the equipment is used in accordance with its intended use.
(ðSection2.2,Page8)
2.9 Explosion protection
!DANGER
Always observe the information on explosion protection given in this section when
operating the product in potentially explosive atmospheres.
Pumps/Pump sets must not be used in potentially explosive atmospheres unless
marked as explosion-proof and identified as such in the data sheet.
Special conditions apply to the operation of explosion-proof pump sets in accordance
with 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1.6,Page7) to (ðSection2.9.3,Page11)
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.
For information on application options of individual components (if any) in
potentially explosive atmospheres, refer to the manufacturer's product literature.
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 Safety
11 of 106
Omega / Omega V
1384.8/17-EN
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 lists the temperature classes and the resulting maximum permissible
temperature limits of the fluid handled. 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 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 EN13463-1 or
ISO80079-36
Maximum permissible fluid temperature
T1 Maximum 140°C2)
T2 Maximum 140°C
T3 Maximum 140°C
T4 80°C
T5 45°C
T6 Not permitted
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 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, 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 Repair
Special regulations apply to repair work on explosion-proof pumps. Modifications or
alterations of the pump set can affect explosion protection and are only permitted
after consultation with the manufacturer.
Repair work at the flameproof joints must only be performed in accordance with the
manufacturer's instructions. Repair to the values in Table 2 of EN60079-1 is not
permitted.

NOTE
Observe the manufacturer's instructions for application/removal of the preservative.
If commissioning is to take place some time after delivery, we recommend that the
following measures be taken:
▪Store the pump and supplied components under dry, vibration-free conditions,
and, if possible, in their original packaging.
▪The ambient temperatures for transport and storage must not be below -20°C or
above 60°C.
1. Manually rotate the pump shaft once a month with a suitable tool.
2. Spray preservative through the suction nozzle and discharge nozzle. It is
advisable to then close the pump nozzles (e.g. with plastic caps or similar).
3.4 Return to supplier
1. Drain the pump as per operating instructions. (ðSection7.3,Page62)
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, the pump must also be neutralised, and anhydrous inert gas must be
blown through the pump to ensure drying.
4. Always complete and enclose a certificate of decontamination when returning
the pump.
Indicate any safety measures and decontamination measures taken.

Design The pump is designed with a tangential fluid inlet and a tangential fluid 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 tangentially via the suction nozzle (1) and is accelerated
outward by the rotating impeller (5). 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 (10), where it leaves the pump. The clearance gap (6) prevents
any fluid from flowing back from the casing to the suction nozzle. The shaft (7)
enters the hydraulic system through the volute casing (4). The shaft passage through
the sealing housing is sealed to atmosphere with a shaft seal (9). The shaft runs in
rolling element bearings (3 and 8) located in a bearing housing (2) which is
connected to the volute casing (4).
Sealing The pump is sealed by a shaft seal (standardised mechanical seal or gland packing).
