3 Transport and storage
3.1 Transport and handling
The transport and handling of the equipment must be
carried out using suitable means in line with the
weight to be supported. The weight is generally
shown on the delivery note or on the data plate. If it is not, and
the equipment cannot be handled safely, please contact KSB
ITUR.
Remember that the equipment should never be lifted using the
ring bolts of each of the elements, e.g. the motor and pump
ring bolts, which are exclusively for independent transport.
It is also important not to use the pump and
pipe flanges or joining elements, e.g.
couplings.

Impeller type:
- A (semi-open)
- C (channel)
- V (vortex)…
Series
If the equipment is to be lifted using straps,
these must always be run underneath the
motor and pump support.
Do not position the pump on the filter/suction
hood. When positioning the pump outside of
the well on the ground, place a wood plug at the height of the
casing in order to prevent the suction hood from being a
support point for the pump.
When the pumps are dismounted from their transport
pallet, suitable means must be used to ensure the
stability of the equipment, until it is finally secured at
its definitive location.
3.2 Provisional storage/conservation
During provisional storage, it is only necessary to protect with
preservation products those low alloy parts in contact with the
liquid (e.g. grey cast, nodular cast, etc). Preservation products
available on the sector market can be used, in line with the
manufacturer's instructions on application and disposal.
The pump, or motor pump, shall be deposited in a dry site
where the relative humidity is as constant as possible.
When stored outside, it is necessary to keep the pump/motor
pump in an impermeable box, ensuring it does not come into
contact with external humidity.
Protect the stored product from humidity, dirt,
parasites and unauthorised access! All
openings must remain closed, and must not be opened until
necessary during assembly!
The shiny (mechanised) parts and surfaces of the pump must
be protected from corrosion using silicone-free oil or grease.
The electric motor must be disconnected, the
connection cables removed and the terminal box
closed with its cover on. The switchboards must be
in vertical position and disconnected.

- 100 / 250 V
4.3 Form of construction
Volute pump casing with axial suction and radial impulsion.
Single-stage impeller semi-open, channel or vortex. Suction
hood.
Note
The RWCP series has a discharge pipe to the outside of the
base plate.
The RWCN series does not have a discharge pipe.
Bearings
: Both series are fitted with two classes of bearing:
grease-lubricated ballbearings or friction bearings lubricated
by the pumped liquid (when possible) or through the exterior
injection of liquid or grease.
Shaft sealing
: The standard sealing system is by way of a
retainer. This can be done optionally using a packing or
mechanical seal.
