11 Stator 12 Integrated power cable
Design The hydraulic system and the motor are firmly connected and form a close-coupled
unit.
Both impeller (1) and rotor (10) are arranged on a common shaft (9).
Function The shaft runs in product-lubricated plain bearings (3 and 6). The rotor space is
sealed off towards the stator space by the can (4). The can, which is made of
corrosion-resistant material, rests on the stator (11) and the support sleeves (5) to
compensate for the forces resulting from the pressure within the rotor space.
The bearings are lubricated by the pumped fluid in the rotor space. When the pump
set is started up, the fluid enters the rotor space through the bores (2 and 8) and
vents the rotor space through a bore in the shaft. The partial flow tapped from the
product flow through the bores (2 and 8) surrounds the rotor during pump operation
and enters an axial bore provided at the rear end of the rotor shaft. The axial bore
ends at the front face of the impeller-side shaft end.
The pressure difference between the bores (2 and 8) and the outlet of the axial bore
through the shaft at the impeller-side shaft end results in a continuous partial flow
of fluid handled. As this partial flow passes through the circular clearance between
the rotor and the can, it dissipates the heat generated in the motor. The intensive
exchange of liquid from the hydraulic space to the rotor space and back to the
suction side of the hydraulic system at the same time ensures sufficient lubrication of
the plain bearings.
Depending on the pump model, the pump set is connected to the power supply
either via a terminal box (7) or an integrated power cable (12) which is firmly
connected to the motor. Depending on the technical version, additional equipment
such as temperature sensors for monitoring the rotor space temperature (Pt100) can
be provided in the motor.

4 Description of the Pump (Set)
18 of 76 Etaseco/ Etaseco-I
PTC thermistors for monitoring the winding temperature can optionally be fitted. On
pump models with "integrated power cable" the temperature sensors can optionally
be connected via an additional power cable.
Sealing The pump is a seal-less canned motor pump.
It is sealed by static O-rings. It is not fitted with any dynamic sealing elements.

5.1 Safety regulations
DANGER
Installation in potentially explosive atmospheres
Explosion hazard!
▷Never install the pump in potentially explosive atmospheres.
▷Observe the information given in the data sheet and on the name plates of the
pump system.
5.2 Checks to be carried out prior to installation
Place of installation
WARNING
Installation on mounting surface which is unsecured and cannot support the load
Personal injury and damage to property!
▷Use a concrete of compressive strength class C12/15 which meets the
requirements of exposure class XC1 to EN206-1.
▷The mounting surface must have set and must be completely horizontal and
even.
▷Observe the weights indicated.
CAUTION
Exceeding the permissible power cable bending radius
Damage to the power cable!
▷Observe the permissible minimum bending radius indicated in the data sheet
provided by the cable manufacturer or stated on the order-specific outline
drawing; if required, contact KSB.
1. Check structural requirements.
All structural work required must have been prepared in accordance with the
dimensions stated in the outline drawing/general arrangement drawing.
2. When selecting the place of installation make sure that connections 6B, 10E and
11E can easily be accessed during pump operation.

5.3.1 Horizontal installation
5.3.1.1 Installation without baseplate
Fig.7: Horizontal installation
üThe installation surface has the required strength and characteristics.
üThe installation surface has been prepared in accordance with the dimensions
given in the outline drawing/general arrangement drawing.
üThe plug fixings used are suitable for the pump weight.
1. Remove the covers from the suction and discharge flanges.
2. Position the pump set on the installation surface and support the motor end in
such a way that the discharge nozzle flange is in horizontal position.
3. Use shims for height compensation, if necessary.
All shims must lie perfectly flush.
4. Insert the fastening bolts into the casing foot and tighten them lightly.
5. Align the pump set with the help of a spirit level placed on the motor housing
and the discharge nozzle.
6. To prevent any stresses and strains when tightening the bolts completely,
remove any supports from underneath the pump set.
7. Tighten the fastening bolts completely.
