6. Commissioning, start-up / Shutdown

Do not use the pump for fluids to which its materials are not
resistant.
Before starting up the pump make sure that the following points
have been checked and carried out in acc. with sections 5.3, 5.4
and 5.5.
Make sure to check:
-- the operating data
-- the direction of rotation
-- the electrical connections
-- the correct installation of the pump
-- that all shut--off elements installed in the system are fully
open
6.1 Commissioning / start- -up
Before starting up the pump, make sure that the liquid level can
never drop below dimension R (see dimension tables, p.
68--69).
For continuous operation (S1) the pump must be fully sub-
merged.
Operation outside the fluid will result in increased wear
and must be avoided!
6.1.1 Filling level in the tank
Maximum filling level: 4 m
6.1.2 Fluid temperature
The plant operator is responsible for ensuring that fluid tem-
perature does not exceed 40°C.
Operation at a temperature of 70°C is permitted for a short
period (3 to 5 minutes).
6.1.3 Switching frequency
Maximum number of start--ups per hour: 15
6.1.4 Operating voltage
Deviations between the operating voltage and the pump volt-
age must be less than 10 %.
6.1.5 Density of fluid pumped
Max. density: 1.1. For higher densities please contact KSB.
6.2 Shutdown / storage / preservation
6.2.1 Storage of new pumps
-- Store the pump in upright position in a dry location at tem-
peratures above 0°C in its original packaging.
6.2.2 Measures to be taken for prolonged shutdown
The pump remains installed
In order to make sure that the pump is always ready for instant
start--up, start the pump set regularly once every 3 months for a
short time (approx. 1 minute). Before doing so, make sure that
the liquid level in the sump or tank is above dimension R.
6.2.2.2 The pump is removed from the sump and stored
Before putting the pump into storage:
-- Carry out the checks and maintenance work stated in section
7.1.
-- Clean the pump and spray paraffin oil into the pump through
the suction and discharge nozzles.
-- Protect the pump against dust.
-- Check the electric cable for damage and attach it to the pump
handle, to prevent it from trailing on the floor. Cap the cable
end.
-- Then apply preservatives as described in section 6.2.1.

Servicing / maintenance

7.1

General instructions

Work on the unit must only be carried out with
the electrical connections disconnected (incl.
control cable).
Pumps handling liquids posing health hazards must be
decontaminated. When draining the fluid see to it that
there is no risk to persons or the environment. All relevant laws
must be heeded.
7.2 Servicing / inspection
In case of damage or if the pump needs to be overhauled, we
recommend to contact KSB's customer service (see enclosed
directory of addresses).
Please observe the following when performing mainten-
ance work:
• Check the pump set for even, quiet running and make sure
that the impeller turns smoothly. Then disconnect the pump
from the power supply.
• Hose down the pump and waste water reservoir at least once
a year.
• Check the electric cable for damage and replace, if necess-
ary.
• Visually inspect the pump, incl. accessories and fastening
elements (replace defective parts).
Replace damaged components by original spare parts.
Recommended oil quality:
Paraffin oil, thin--bodied, HAFA CLAREX OM, Merck No. 7174
or equivalent non--toxic and ecologically acceptable oil (type
Codex).
Alternatively, all non--doped and doped motor oils of grade SAE
10W to SAE 20W can be used. Please observe the local laws
applicable to the disposal of such substances!
7.3

Dismantling the pump

General instructions
Repair and maintenance work must only be performed by
specially trained personnel.
Observe the safety regulations laid down in section 7.1.
The pump set shall be dismantled in accordance with the asso-
ciated sectional drawing on p.
1. Undo screws 914.01 at cable gland 834.
2. Take the cable gland off pump casing 100.
3. Disconnect the cable gland from stator 81--59.
4. Undo screws 914.03 on suction cover 162.
5. Remove the suction cover.
6. Undo screws 914.02 on bearing bracket 330.
7. Position the pump with impeller 230 pointing upwards and
pull out the entire rotor assembly (818 + 330 + 230) by the
impeller.
8. Unscrew the impeller from the rotor assembly.
9. Push the spring--loaded mechanical seal ring 433.02 along
the shaft.
10. Drain the bearing bracket.
11. Pull the bearing bracket off the rotor assembly.
12. Remove the seat ring of mechanical seal 433.02 and shaft
seal ring 421 from the bearing bracket.
13. Pull rolling element bearings 321.01 and 321.02 off rotor
assembly 818.
14. Take circlip 932 off the rotor.
