2 Installation
2.1 Installation and operational accessories
The motor is supplied with a 3 meter long, 3 core waterproof
cable.
The following accessories are necessary for installation and
commissioning :
• A cable with vulcanizing rubber compound (which is normally
used for repairing the punctures in automobiles) and electric
insulation PVC tapes.
• Control panel
• 2 pairs of supporting or installation clamps for vertical
installation and 1 set of stands for horizontal installation.
• Overload trip unit, water level guard, single-phase preventor
(for 3 phase motor).
2.2 Motor preparations
2.2.1 Motor fill
For filling the motor with pure cold drinking water, follow the
procedure given below :
• Place the motor vertically up.
• Remove the two plugs provided at the top of the motor (Here
one plug is provided to escape the air and another for filling
the water).
• Fill the motor completely with pure water having no impurities
(Do not use distilled water).
• After filling the motor let it stand for 30 minutes and rotate the
rotor by hand to accelerate the escape of trapped air.
• At the same time pour more water to fill the loss of volume
caused by the escaped air bubbles.
• Refit the plugs.
• Check the motor completely for any leakages of water.

Submersible motor pumps (100 mm)
Now motor is ready for operation.
If a unit has been in storage for more than 2 months, check for
the motor filling and for rotor freeness.
2.2.2 Insulation resistance (IR)
The insulation resistance value of the new motor with 500 V DC
megger is generally 20 Mega Ohms. For older motors if the value
observed to be less than 2 Mega Ohms, please contact KSB or
Authorized Dealer before switching on the motor.
2.2.3 Extended Cable connection
Only the proper cable connector ensures a perfect watertight
joint and provides a protection against mechanical damage to
the cable jointing. While connecting extra cable beyond standard
length along with the pump set, it is necessary to have a water
tightened cable joint.
a. To connect the cables, cut off and strip the motor cable and
join it is staggered fashion where no 2 joints overlap each
other.
b. Colors of the leads, which are to be joined together must be
identical as per following sketch (Fig. 1).
c. Wrap vulcanizing rubber compound to each cable joint and
again wrap with electric insulation tape on the top of it.
d. To ensure proper insulation once again wrap with vulcanizing
rubber compound and electric insulation tape for each joint.
e. Finally wind the total cables with electric insulation tape.
f. Oil or grease should not have any contact with the tape.
g. Complete the taping over core insulation at each side.
Please see that each turn of the tape should have a 50% overlap
over the previous turn. The tape should be wound on to a
thickness at least equal to that of core insulation.
2.2.3.1 Selection of Cable
Voltage drop for extended cable should not be more than 3% of
rated voltage i.e.
Permissible voltage drop = Available voltage x 0.03
For Single phase :
Voltage drop = 2 x Cable Length in meters x Resistance / meter
for particular cable size x motor current
Allowed voltage drop is up to 7.0 volts (Considering available
voltage 230 volts).
e.g. For the cable length of 50 m and area of cross section 1.5
mm2, with rated current 3.5 A,
Voltage drop = 2 x 50 x 0.0121 x 3.5
= 4.24 volts (which is permissible)
For three phase :
Voltage drop = Cable Length in meters x Resistance / meter for
particular cable size x motor current
Allowed voltage drop is up to 12.5 volts (Considering available
voltage 415 volts).
e.g. For the cable length of 50 m and area of cross section 1.5
mm2, with rated current 2.4 A,
Voltage drop = 50 x 0.0121 x 2.4
= 1.45 volts (which is permissible)
Resistance / meter according to cross-section area :

2.2.4 Coupling of pump and motor
Couple the shaft to motor in vertical manner.
Before fitting the suction strainer the effortless rotation of the
coupled rotor should be checked at the sleeve coupling.
Please ensure that the top face of sand guard presses the bottom
face of the sleeve coupling to avoid the entry of sand inside the
coupling.

Submersible motor pumps (100 mm)
2.3 Typical installation at site
Use lifting device of capability of carrying the weight of pump
unit as well as the weight of pipe filled with water for installation.
2.3.1 Vertical installation
Before installing the unit in narrow deep wells, the well should be
tested for trueness of size over its entire length (e.g. by running
a dummy cylinder of diameter 98 mm and length about 2 m inside
the well). A slight inclination of the well is immaterial, whereas
any twists or bends can make installation difficult.
Installation depth should be selected such that the motor would
never run dry even when the water level is at its lowest mark
(i.e. draw down of bore well capacity).
The minimum water level should be 0.5 m above the top of the
non-return valve.
The pump should always be installed with the suction strainer
above the slotted casing pipe. The effect is that the pump draws
in the water free from loose sand.

4. Expansion joint
Note : Generally the horizontal installation of submersible pump
unit is equipped with two storage tanks to increase the water
capacity.
1. Referring to the above figure (Fig. 4) for horizontal installation
only two supports are needed. One is placed at the extreme
end of the NRV while other is placed at the center of motor.
2. Install adapter pipe to the pump with 2 Water reservior and
the motor with proper fittings.
3. Ensure that the cast RCC foundation is incorporated with
the recommended foundation bolts of proper height.
4. To make up the correct center height of aligned pump - motor,
provide sufficient metallic packing in the RCC foundation
itself. To attain precise alignment, minor shims up to 2 mm
thick made of M.S. sheet may be used below the pump or
motor stand.
5. Such installed pump shall be either perfectly horizontal or
maximum of 5 degree inclination with motor down and pump
lifted up from the ground. Precise tightening of foundation
bolts has to be done at the final stage.
6. Surface of the motor should be cleaned periodically for

It is important to ensure that pump does not sit on the base of the
well and there is no risk of sand or sludge deposition around the
motor. This would disrupt heat dissipation from the motor.
2.3.3 Plastic / Flexible Rubber riser piping instead
of normal GI riser piping
Consult the HDPE / rubber pipe suppliers for the capability of
pipes for withstanding the pressure. If the pump is to be fitted
with HDPE raising piping, it is to be firmly tied up with stainless
steel wire ropes of dia. 2-3 mm to the eyelets on the non return

valve body and the vertical pipe line. This precaution will help
even in case of GI riser piping.
2.3.4 Installation of water level guard
Install a water level guard for dry running protection to avoid the
damage of pump unit in case of water level fluctuations.
2.3.5 Protection against electric shock
Submersible motors are provided with external earthing plug at
upper bearing body as a standard. A three-cored cable is led out
of the motor. The operator / user shall be responsible for proper
connection of the earthed conductor and of control unit at site.
2.3.6 Fixing the power supply cable to the riser pipe
During installation of pump into the bore well, power supply cable
should be fixed to the raiser pipe by means of cable clips at a
distance of approx. 3 m immediately after the flange or coupling
of the pipe.
2.3.7 Verification of power line with respect to
motor design
Verify the voltage and frequency of main supply with the data
given on the motor’s nameplate.
If it is not matching then consult with concerned electrical
authority.
Ensure that the main power supply is stable.

2.4.2 For three-phase motor
2. Using pressure gauge, check the discharge pressure in both
the direction of rotations. The higher value corresponds to
the correct direction of rotation. OR
3. By visual inspection see the flow rate in both cases. If water
comes out up to the short length through the raiser pipe, flow
rate is lower while if it comes farther, results in higher flow
rate. The higher flow indicates the correct direction of rotation.
For Single-phase motors
In case of single-phase AC motors the direction of rotation of the
motor itself corresponds to the correct direction of rotation of the
pump, irrespective of mode of connection to the power supply.
3.4 Discharge valve position during initial start-
up
During initial start-up the pump should run with the discharge
valve slightly open (approx. 1/3 of full opening). The water is
examined for sand content (The permissible sand contents for
warranty is 50 mg / liter) at this stage it is important that pump is
run continuously without stooping (if pump is stop, sand will settle
inside the pump and pump is block resulting in damage) till the
sand content in the water falls to an unnoticeable level OR Flush
the bore well completely before new pump installation.
3.5 Operation against a closed discharge valve
Pumps should not be allowed to run against a closed discharge
valve for longer than 5 minutes. This would cause the water in
the pump to warm up quickly and the heat would be transferred
to the motor, which causes a risk to the motor.

3 Commissioning and start up
3.1 Verification of rated current
Please refer to the motor nameplate for the values of rated current
required for relay setting.
3.2 Switching ON of mains
The pumping set should be switched on only if it is fully immersed
in the water.
3.3 Checking the direction of rotation
For three-phase motors
1. Let the pumping set run for a short time against a closed
discharge valve, in both the directions of rotation and check
the flow. Reversing of two points of connection, reverses
the direction of rotation. The higher flow rate gives the
direction of rotation. OR
3.6 Operation against a throttled discharge valve
If the pump set is to be operated against a throttled discharge
valve for a prolonged period of time, the minimum rate of flow
should be at least 10% of flow at the best efficiency point * (BEP)
of the characteristic curve, this must be observed in order to
reduce noisy operation and the overheating of the pump set.
* For best efficiency point (BEP) of the characteristic curve
consult with KSB dealer.
Actual start-up
• Check the power supply condition as per the name plate.
• Do proper earthling.
• Fix the pressure gauge before discharge valve.
• Set the relay as per current value given on name plate and
start the pump.
• Set the duty parameters as per value given on name plate by
control valve.
• Pump should run always on duty point specified on name plate
3.7 Operating limits of pump
Operational safety requirements stipulate that pump may only
be operated continuously within the flow rate and pump head
limits which are specified on nameplate. Otherwise ±10% of best
efficiency flow rate should be the pump operation range, provided
that motor is not overloaded. (For ensuring this the motor current
should not exceed as specified on name plate).
3.8 Switching frequency
In order to prevent the motor from heating up excessively due to
many switching cycles, a maximum of 15 starts per hour are
permitted with a minimum of 3 minutes interval as a shut down
period between two successive starts.
5
Submersible motor pumps (100 mm)
3.9 Interruptions / Shutdown periods
In order to ensure a long motor service life, pumps should not be
allowed to remain idle in water for more than 8 to 10 days.
Otherwise fine deposits like lime, iron and other substances tend
to settle in the bearings and impeller gaps. This might block the
pump rotor. In case the situation is unavoidable, it is
recommended to run the pump for at least 10 to 15 minutes every
week. This will enable the pump to resume instant service at
any time.
4 UMT (S) 100 motors
Special attention on following points is required :
4.1 The motor is hermetically sealed induction
motor
It is pre-filled with liquid at works with rotor and bearings being
lubricated and cooled by the filled liquid. The motor is designed
for vertical and horizontal location in clean water, with a maximum
sand content of 50 g/m3. The maximum installation depth is 300
m.
