cold or moving parts, and check that the equipment functions properly.
▪Do not remove any protective equipment (e.g. contact guards) during operation.
▪Provide the personnel with protective equipment and make sure it is used.
▪Contain leakages (e.g. at the shaft seal) of hazardous fluids handled (e.g.
explosive, toxic, hot) so as to avoid any danger to persons and the environment.
Adhere to all relevant laws.
▪Eliminate all electrical hazards. (In this respect refer to the applicable national
safety regulations and/or regulations issued by the local energy supply
companies.)
▪If shutting down the pump does not increase potential risk, fit an emergency-
stop control device in the immediate vicinity of the pump (set) during pump set
installation.
2.7 Safety information for maintenance, inspection and installation
▪Modifications or alterations of the pump (set) are only permitted with the
manufacturer's prior consent.
▪Use only original spare parts or parts/components authorised by the
manufacturer. The use of other parts/components can invalidate any liability of
the manufacturer for resulting damage.
▪The operator ensures that maintenance, inspection and installation is performed
by authorised, qualified specialist personnel who are thoroughly familiar with
the manual.
▪Only carry out work on the pump (set) during standstill of the pump.
▪Only perform work on the pump set when it has been disconnected from the
power supply (de-energised).
▪The pump (set) must have cooled down to ambient temperature.
▪Pump pressure must have been released and the pump must have been drained.

2 Safety
10 of 116 Vitalobe
▪When taking the pump set out of service always adhere to the procedure
described in the manual. (ðSection6.3,Page45)
▪Decontaminate pumps which handle fluids posing a health hazard.
▪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38)
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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.
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
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.
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 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 class 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.

T4 105°C
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.
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.
In a potentially explosive atmosphere the pump sets must be equipped with a
pressure relief valve. If the pump has not been fitted by the manufacturer with a
pressure relief valve, the operator must fit the pump with a pressure relief valve (e.g.
bypass valve) on site.
Contact KSB for further information on monitoring equipment.

Design The pump is designed with a radial fluid inlet and outlet in either horizontal or
vertical position. The hydraulic system is connected to the motor by a shaft coupling.
Normally, frequency inverter controlled geared motors are used. The pump and the
motor are mounted on a common baseplate.
Design standard The Vitalobe pump series is available in two design standards, which only differ in
the pump head design. The bearing bracket and gears are identical.
Design standardB: available for sizes 100-680; non-countersunk rotor screws,
confined O-rings
Design standardBB: available for sizes 100-490; counter-sunk rotor screws, flush
mounted O-rings
Function The fluid is pumped by two counter-rotating impellers (3) with intermeshing rotary
lobes inside the pump casing (2). Each impeller (3) is mounted on a shaft (6) by means
of a screw (4). The shafts run in bearings located in the bearing housing (11). Shaft
rotation is synchronised via spur gears (10), which transfer the torque of the driving
shaft (9) to the driven shaft. The impellers (3) inside the casing (2) are synchronised
such that they do not contact each other. As soon as the impeller lobes disengage,
the increasing volume between the lobes creates a vacuum on the suction side,
drawing the fluid through the suction nozzle (1) into the pump casing. The fluid is
trapped in the space between the impellers (between the lobes) and transported
through the rotor casing to the pump's discharge nozzle (14). As soon as the
impellers re-engage, the volume between them decreases, the pressure at the
discharge (14) increases, and the fluid is forced out of the pump casing. The pump set
