3 Transport/Temporary 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.
▷ Give due attention to the weight data and the centre of gravity.
▷ Observe the applicable local health and safety regulations.
▷ Use suitable, permitted lifting accessories, e.g. self-tightening lifting tongs.
To transport the pump/pump set suspend it from the lifting tackle as shown.
Fig.1: Transporting the pump set
3.3 Storage/preservation
CAUTION
Damage during storage by humidity, dirt or vermin
Corrosion/contamination of the pump (set)!
▷ For short-term outdoor storage cover the pump (set) or the packaged pump
(set) and accessories with waterproof material.

Wet, contaminated or damaged openings and connections
Leakage or damage to the pump!
▷ Clean and cover pump openings and connections as required prior to putting
the pump into storage.
3 Transport/Temporary Storage/Disposal
12 of 52
Etaline DL
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.
▪ Exposed locating surfaces (shaft ends, flange faces, centring spigots, connector
contacts) are treated with a layer of temporary corrosion protection (< 6 months)
for transport. Take suitable corrosion protection measures for extended storage
periods.
▪ Replace closed rolling element bearings after 48 months of storage.
If properly stored indoors, the equipment is protected for a maximum of 12months.
New pumps/pump sets are supplied by our factory duly prepared for storage.
For storing a pump (set) which has already been operated, observe the measures to
be taken for shutdown. (ðSection6.3.1,Page30)
3.4 Return to supplier
1. Drain the pump as per operating instructions. (ðSection7.3,Page36)
2. Always flush and clean the pump, particularly if it has been used for handling
noxious, explosive, hot or other hazardous fluids.
3. If the pump set 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 set 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 (set).
Always indicate any safety and decontamination measures taken.
(ðSection13,Page50)
NOTE
If required, a blank certificate of decontamination can be downloaded from the
following web site: www.ksb.com/certificate_of_decontamination
3.5 Disposal
WARNING
Fluids handled, consumables and supplies which are hot and/or pose a health
hazard
Hazard to persons and the environment!
▷ Collect and properly dispose of flushing fluid and any fluid residues.
▷ Wear safety clothing and a protective mask if required.
▷ Observe all legal regulations on the disposal of fluids posing a health hazard.
1. Dismantle the pump (set).
Collect greases and other lubricants during dismantling.
2. Separate and sort the pump materials, e.g. by:
- Metals
- Plastics
- Electronic waste
- Greases and other lubricants
3. Dispose of materials in accordance with local regulations or in another
controlled manner.

with a maximum shaft power of 150kW) implementing "Ecodesign"
Directive 2009/125/EC
▪ Minimum efficiency index: see name plate, key to name plate
▪ The benchmark for the most efficient water pumps is MEI ≥ 0.70.
▪ Year of construction: see name plate, key to name plate
▪ Manufacturer’s name or trade mark, commercial registration number and place
of manufacture: see data sheet or order documentation
▪ Product’s type and size identificator: see name plate, key to name plate
▪ Hydraulic pump efficiency (%) with trimmed impeller: see data sheet
▪ Pump performance curves, including efficiency characteristics: see documented
characteristic curve
▪ The efficiency of a pump with a trimmed impeller is usually lower than that of a
pump with full impeller diameter. Trimming of the impeller will adapt the pump
to a fixed duty point, leading to reduced energy consumption. The minimum
efficiency index (MEI) is based on the full impeller diameter.
▪ Operation of this water pump with variable duty points may be more efficient
and economic when controlled, for example, by the use of a variable speed drive
that matches the pump duty to the system.
▪ Information on dismantling, recycling and disposal after decommissioning:

Design
The pump is designed with a radial fluid inlet (suction nozzle) and a radial outlet
(discharge nozzle) arranged on the same axis. The hydraulic system is rigidly
connected to the motor by a shaft coupling.
Function
The fluid enters the pump via the suction nozzle (2) and is accelerated outward by
the rotating impeller (4). 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 (1), where it leaves the pump. The clearance gap (3) prevents any fluid from
flowing back from the casing to the suction nozzle. At the rear side of the impeller,
the shaft (7) enters the casing via the casing cover (6). The shaft passage through the
cover is sealed to the atmosphere with a dynamic shaft seal (5). The shaft runs in
rolling element bearings (9 and 11), which are supported by a motor housing (10)
linked with the pump casing and/or casing cover via the drive lantern (8).
Sealing
The pump is sealed by a standardised mechanical seal.
