4 Description of the Product and
Accessories
4.1 Technical Specification
The KSB pump of the RDLO type series is a
horizontally installed, single-stage, axially split
volute casing pump with double-entry radial
impeller. Connecting flanges are manufactured on
option to ISO, DIN EN, or ASME.
RDLO is designed for use in waterworks, irrigation
and drainage pumping stations, power stations,
industrial water supply systems, shipbuilding as well
as general petrochemical applications.
4.2 Design Details
4.2.1 Pump Casing
Axially split volute casing with replaceable casing
wear rings.
Suction and discharge nozzles in the lower casing
half are at the same level (in-line design).
4.2.2 Impeller
The double-entry radial impeller is manufactured for
the individual operating data; including wear rings, if
requested.
In double-entry radial impellers the axial thrust is
largely balanced.
4.2.3 Pump Shaft
The shaft is fully sealed against the medium
pumped. Shaft protecting sleeves are fitted in the
seal area.
4.2.4 Shaft seal
The shaft is sealed on the driven and non-driven
ends by a gland packing or by a balanced
mechanical seal that is independent of the direction
of rotation.
The gland packings mounted on KSB pumps are
asbestos-free and suitable for drinking water
applications.
For a description of the mechanical seal, see
section 9.5.
4.2.5 Bearings and Lubrication
The pump is fitted on either side with grease-
lubricated or oil-lubricated (optional) rolling element
bearings. The locating bearing is situated on the
driven end.

5 Installation at Site
5.1 Safety Regulations
Electrical equipment operated in
hazardous locations of the zone 1 must comply
with the explosion protection regulations. This
is indicated on the motor rating plate.
If the equipment is installed in hazardous
locations, the applicable local explosion
protection regulations and the regulations of the
test certificate supplied with the equipment and
issued by the responsible approval authorities
must be observed and complied with.
The test certificate must be kept close to the
location of operation for easy access (e.g.
foreman's office).
5.2 Checks to Be Carried Out Prior to
Installation
All structural work required must have been
prepared in accordance with the dimensions
stated in the installation drawing.
The concrete foundations shall have sufficient
strength (min. BN 150) to ensure safe and
functional installation in accordance with DIN
1045 or equivalent standards.
Make sure that the concrete foundation has set
firmly before placing the unit on it. Its surface should
be truly horizontal and even.
5.3 Installing the Pump / Unit
Prior to installing the pump, check
the operating data. Check the
data on the name plate for compliance with the data
in the purchase order and the system data, e.g.
operating voltage, frequency, medium temperature,
etc.
The installation drawing in section 9.1 must be
observed.
