Horizontal installation -- 3 E
Works-No.: see nameplate
The operating manual contains important information and hazard/danger
warnings. It is imperative to read the instructions set out in the manual prior
! to installation, making electrical connections and commissioning. Additional
operating instructions relating to the components of this plant will also have
to be observed.
In principle if any work has to be carried out to the plant all electrical supplies
(inclusive of the control cable) should be disconnected at the mains supply
switch. The plant has to be safeguarded against accidental starting.

the manual.
Work on the machine must be carried out only during standstill.
The shutdown procedure described in the manual for taking the
machine out of service must be adhered to without fail.
Pumps or pump units handling media injurious to health must
be decontaminated.
Immediately following completion of the work, all safety--rele-
vant and protective devices must be re--installed and/or re--acti-
vated.
Please observe all instructions set out in the chapter on ”Com-
missioning” before returning the machine to service.
2.7 Unauthorized Modification and
Manufacture of Spare Parts
Modifications or alterations of the machine are only permitted Fig.1: Transport of pump (Fig.0)
after consultation with the manufacturer. Original spare parts
and accessories authorized by the manufacturer ensure safety.
The use of other parts can invalidate any liability of the manu-
facturer for consequential damage.
2.8 Unauthorized Modes of Operation
The warranty relating to the operating reliability and safety of
the pump / unit supplied is only valid if the machine is used in
accordance with its designated use as described in section 1
of these operating instructions. The limits stated in the data
sheet must not be exceeded under any circumstances.

The motor eyebolts must only be used for lifting the mo-
tor alone, never for lifting the complete unit.

Safe transport in horizontal position must be ensured by
suitable transport facilities. Make sure the pump cannot
slip out of the transport arrangement.
3.2 Interim Storage / Preservation
When the unit is temporarily put into storage, only the wetted
low alloy components, e.g. JL1040 (GG--25) must be preser-
ved. Commercially available preservatives can be used for this
purpose. Please observe the manufacturer’s instructions for
application / removal.

The KSB pump of the Omega series is a horizontally installed,
single--stage, axially split volute casing pump with double--en-
try radial impeller. Connection flanges are manufactured accor-
ding to EN, DIN, ISO, BS or ASME, as preferred.
Fields of application
In waterworks, irrigation and drainage pumping stations, power
stations, for industrial water supply, dock installations, fire ex-
tinguishing systems, refineries, pipelines and tank farms, also
for handling crude oil and refinery intermediates

6.4.1 Checking the Direction of Rotation
Caution For trouble--free operation of the pump, the
correct direction of rotation of the impeller is of
paramount importance.
If running in the wrong direction of rotation, the pump cannot re-
ach its duty point; vibrations and overheating will be the conse-
quence. The unit or the shaft seal might be damaged.

Cutting the packing rings to size
If moulded packing rings are not available, the rings can best
be cut to size using a special cutting gauge. If no cutting gauge
is available, take a tube with the same diameter as the shaft,
wind the packing around the tube in a spiral and cut the rings
from the spiral. We recommend a straight cut.
Installing the packing rings
Push the packing rings with the stuffing box insert into the gland
space one by one. The joints of the packing rings must be offset
by 90_. The number of rings and the arrangement of the lantern
ring are shown in the general drawing (see appendix). After fit-
ting all the packing rings, put on the stuffing box insert and gland
cover and tighten them so that the packing rings adapt to the
gland space. Then loosen the gland cover again to relieve the
load on the packing. This procedure is not necessary if moulded
packing rings are used.
Commissioning
When the pump is started up, the gland must only be gently tigh-
tened (by hand). A high leakage rate (approx. 50 to 200 drops
per minute), depending on the liquid being pumped, must be ac-
cepted until the packing material has settled and has adapted
to the temperature conditions (approx. 10 to 15 minutes).
Then the gland cover must be carefully and evenly tightened to
reduce the leakage to a minimum. If there is no leakage, there
is a risk that the packing will run hot.

8.2.1 Mechanical Seal ”Type M 7 N 4”
(Shaft unit dw 40 to 80 mm)
The mechanical seal type M 7 N 4 used is a single--acting, bi--
rotational, non--balanced seal which does not require circula-
tion pipework in cold water applications, due to the pump de-
sign.
Caution Dry- -running of the seal must be avoided at
all costs!
Installation
For the installation of the total seal assembly (mechanical seal,
seal housing) see operating instructions for the pump.
The shaft protection sleeves and also the surfaces of the casing
are subjected to accurate finishing processes with regard to the
O--ring seats, in order to achieve a complete and reliable seal.
Care must be taken during installation to keep these parts ab-
solutely clean, to avoid the surfaces from being damaged and
prevent entry of foreign particles.
The seat ring (8) together with the relevant O--ring (9), is fitted
into the seal cover (see general drawing). The O--ring can be Item Description Material No. of

the seat ring into its position slowly and evenly, lubricating
it with a generous amount of water or alcohol. Use a spacer
sleeve, if necessary. Verify that the seat ring position is nor-
mal to the shaft axis.
-- In the mechanical seal area, the shaft shall be slightly lubri-
cated with water, alcohol or silicone grease. Sealing ele-
ments made of EP rubber must never come into contact
with mineral oil base lubricants (swelling, possibly de-
composition).

J COMMISSIONING
Prime the pump and the seal chamber with the fluid handled
and vent thoroughly. The seal is now ready for operation.
J SAFE OPERATION
For single mechanical seals, the pressure in the seal chamber
of the pump must always exceed ambient pressure, to prevent
any air intake at the seal faces, which would result in dry running
and thus failure of the mechanical seal.
In all operating conditions, the product to be sealed off must be
available in liquid state at the mechanical seal, particularly du-
ring pump start--up and shutdown.
If the operating conditions indicated are observed and the in-
structions given in this operating manual are complied with, the
mechanical seal can be expected to give trouble--free opera-

Sealing / flushing water piping
The pump is equipped with sealing / flushing water piping.
These pipes are sheathed PTFE hoses which are flexible, tem-
perature and highly pressure resistant.
Another favourable property of PTFE (polytetrafluorethylene)
is the extremely low friction coefficient which prevents pipe
clogging.
Normally we supply this assembly ready mounted to the pump.
If this is not the case, mount the hoses and fittings as per the
attached drawings (see appendix).

Push the machines to be coupled together.
Take appropriate precautions to prevent injury by

Make sure to observe dimension S1. On types A and ADS, the
connection between parts 2 and 3 shall be re--established be-

tightening torques and clearance S1 please refer to point 6.6).
Aligning the coupling
(Also refer to section 5.3.2).
The couplings will only tolerate misalignment of the shaft ends
to be coupled to a certain extent.
When aligning the coupling, the radial and angular misalign-
ment of the shaft ends should therefore be minimized. With
identical operating conditions, the useful life of the flexible cou-
pling blocks will be increased as a result.
Coupling alignment shall be effected in two planes which are
normal to each other. Use a straight--edge (radial misalign-
ment) and feeler gauge (angular misalignment) as shown be-
low to verify.

Dismantling and assembly of the rotating unit
The first step is to remove the snap ring (096) from the retainer
(780). The springs are compressed to achieve this. This can
be done by using a simple tool, as illustrated.
Caution Lapped surfaces of the rotating face must
be protected.

The following must be noted during assembly:

Fit the snap ring (096) into the groove of the retainer (780), lea-
ving one end of the snap ring protruding by approx 6 -- 12 mm
to the side of the drilled hole.
At the outer circumference of the retainer (780) there are 2 mar-

The upper groove assists during installation. If the initial ten-
sion of the mechanical seal is set correctly to the installation
length, then the thrust ring shall be in alignment (be flush) with
this groove.
