3 Transport/Storage/Disposal
3.1 Checking the condition upon delivery
1. On transfer of goods, check each packaging unit for damage.
2. In the event of in-transit damage, assess the exact damage, document it and
notify KSB or the supplying dealer and the insurer about the damage in writing
immediately.
3.2 Transport
DANGER
The pump (set) could slip out of the suspension arrangement
Danger to life from falling parts!
▷Always transport the pump (set) in the specified position.
▷Never attach the suspension arrangement to the free shaft end or the motor
eyebolt.
▷Observe the information about weights, centre of gravity and fastening points.
▷Observe the applicable local accident prevention regulations.
▷Use suitable, permitted lifting accessories, e.g. self-tightening lifting tongs.
CAUTION
Improper pump transport
Damage to the bearings!
▷Use a suitable transport lock to prevent axial movement of the pump shaft
during transport.
CAUTION

3 Transport/Storage/Disposal
13 of 62
Etanorm V
1228.87/01-EN
If commissioning is to take place some time after delivery, we recommend that the
following measures be taken for pump (set) storage.
▪Store the pump (set) in a dry, protected room where the atmospheric humidity is
as constant as possible.
▪Rotate the shaft by hand once a month, e.g. via the motor fan.
If properly stored indoors, the pump set is protected for a maximum of 12 months.
New pumps/pump sets are supplied by our factory duly prepared for storage.
For storing a pump (set) which has already been operated, the shutdown measures
must be adhered to. (ðSection6.3.1,Page32)
3.4 Return to supplier
1. Drain the pump as per operating instructions. (ðSection7.3,Page36)
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.
(ðSection11,Page58)

For operating an EtanormV on a frequency inverter which has not been configured
via the KSB selection tool consultation with KSB is required.
For operating pump sets at immersion depths >1000mm with variable-speed system
consultation with KSB is required for the selection.

Design The pump is designed with an axial fluid inlet and a radial outlet. The hydraulic
system is rigidly connected to the motor via a stub shaft and runs in a product-
lubricated SIC/SIC plain bearing on the impeller side, which compensates any lateral
movement or deflection of the shaft. Thanks to the graded lengths of support
column (8) and shaft (6) the pump set can be matched to various immersion depths.
The pump set is mounted on a cover plate (5). The discharge nozzle of the volute
casing (15) is connected with the discharge nozzle (13) of the cover plate via a riser
(14). If on request the pump set is supplied without cover plate and riser, it is
supplied with a bracket.
Function The fluid enters the pump via the suction nozzle (12) and is accelerated outward by
the rotating impeller (11). 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 (15), where it leaves the pump. The clearance gap (16) prevents any fluid from
flowing back from the casing to the suction nozzle. At the rear side of the impeller,

4 Description of the Pump (Set)

1228.87/01-EN
the shaft (6) enters the hydraulic system through the casing cover (10). The shaft runs
in rolling element bearings (2 and 3), which are supported by a motor housing (1)
linked with the pump casing and/or casing cover (10) via the support column (8) and
the drive lantern (4).
Sealing The pump is seal-less with little leakage flowing into the support column (8) at the
shaft passage (9) and then through the overflow opening (7) back to the tank.

5.1 Safety regulations
DANGER
Installing electric equipment (motors) in potentially explosive atmospheres
Risk of explosion!
▷Comply with the applicable local explosion protection regulations.
▷Verify the test certificate of the motor.
▷Keep the test certificate close to the location of operation (e.g. in the foreman's
office).
5.2 Checks to be carried out prior to installation
Check the structural requirements.
The structural work required must have been prepared in accordance with the
dimensions stated in the outline drawing and/or general arrangement drawing.
5.3 Installing the pump set
Foundation The sturdy cover plate 68-3.01 serves as a foundation on which the pump set is
fastened. This cover plate covers the tank opening completely. If the pump set is
supplied with cover plate and riser, the cover plate is supported by a sectional steel
frame provided on the tank.
If ordered without cover plate and riser, the pump set is supplied with a bolted-on
bracket 732. This bracket serves to mount the pump set on the tank.
If pump and motor are delivered separately, transport and installation can be
facilitated by screwing eyebolts into the threaded holes in the lantern for attaching
support ropes.
Installing the pump
1. Carefully align the support frame.
2. Align the base of the bracket.
3. Align the upper flange of the drive lantern with a spirit level.
4. Make adjustments between cover plate and tank edge, if required.
If the pump is installed without suction strainer, observe a minimum distance B
to the tank floor.
