Decreased pump performance and life expectancy can occur if
the water is not cold and clear or contain air and/or gasses.
The maximum sand content in the water must not exceed
50 g/m3. A greater sand content in the water reduces the service
life of the pump and increases the risk of blocking.
When pumping liquids with a density higher than that of water,
motors with correspondingly higher outputs must be used.

For submersible pump's reliable, efficient and trouble free and
long operational life, please ensure the following:
1. A suitable operating environment.
2. An appropriate size of submerisble motor.
3. Completely submerged in cold & clear water.
4. An adequate supply of electricity
Before installation please make sure that:
• The borehole is of appropriate size; ideally the borehole
should have an ID of 8 inch for KPS6 and 10 inch for KPS8.
If the borehole is very large or if the pump-set is to be
installed in an open well or tank, the use of cooling jacket
is recommended.
• The brake horse power of the motor is at least 10% greater
than that the shaft power of the pump.
• The bore is properly treated and tested for the required
discharge.
• The borehole is perfectly vertical and there is no hindrance
inside such as fallen wood etc.
• There is easily accessible IN/OUT from the installation
chamber.
Before starting the installation carefully check the bore visually,
measure the static water level and the total bore depth, also
examine the strata chart of the borehole to locate the blinds and
filters/stainer. Record this obtained data carefully.
Also recheck the intended depth of lowering with the data
obtained and mark the lowering depth of the pump-set on the
strata chart of the borehole for record.
• The water temperature must not exceed 50 °C.
• The maximum density of the pumped liquid must not
exceed 1000 Kg/m3.
• pH of the pumped liquid should be 6 – 8.
• The Supply Voltage variation must be under +6% & -10%.
• All the necessary protections such as overload protection,
under and over voltage protection, phase asymmetry
protection and dry run protection must be installed in the
control unit.
• The motor pump-set should not be operated for more than
3 minutes in zero flow state.
• The fluid flow velocity over the pump-set should be from 16
cm/sec to 96 cm/sec.
• Make sure that the power cable supplied with the motor
pump-set is in good condition and the insulation is not
damaged.
• The installation tools should be placed in proper order for
easy access.
• In order to prevent possible water hammers able to
damage thrust bearing, the use of check valve is highly
recommended.

SERIOUS DAMAGES TO PERSONS AND/OR TO THE PUMP
Submersible pumps and motors are carefully constructed of
high quality materials and are designed to give long trouble free
life. This manual describes the basic procedure for installing,
operating, and maintaining a submersible pump and motor.
Failure to read, understand, and follow the instruction in this
manual, the motor manual, and the instructions for accessory
equipment can cause personal injury, poor performance of the
equipment, shortend life of the equipment, and can void the
warranty on the equipment.
A major portion of the works associated with submersible motor
installation, operation, and maintenance is electrical. It is not
the intent of the manual to provide detailed instruction for this
electrical work.
Read the motor manual and the instructions for other equipment
that is part of the installation and integrated these instructions
with the basic instructions contained in this manual.
Hoisting equipment cable of controlled hoisting and lowering of
the combined weight of the pump, motor, drop cable, column
pipe, and discharge head.
The height of the equipment must be sufficient to
accommodate the longest component to the installed.
Pipe elevators (or equivalent) and lifting bail (or equivalent) for
handling and installing sections of column pipe. The elevators
and lifting bail must be capable of carrying the combined weight
of the pump, motor, drop cable and column pips.
The pump is suitable for both vertical and horizontal installation,
however, the pump should never be installed inclined downwards.
The well should developed with a test pump prior to installing
the submersible pump. Test pumping the well serves several
purposes. It removes the excess sand encountered during the
initial pumping of the well. Attempting to pump mud or sand
with a submersible pump can bury the pump motor causing it
to overheat and burnout. Test pumping also provides a means
of determining the capacity and drawdown (lowering of the
water level in the well during pumping). Pumping sand or other
abrasives with a submersible pump will shorten the life of the
pump and can void the warranty.
The well capacity should equal or exceed the pump capacity. If
the pump removes water at a higher rate than the well produces,
the drawdown will be excessive and the pump will caviate or
"starve" resulting in damage to the pump and motor
The well must be deep enough so that the pump suction is at
least 10 feet below the expected drawdown level. The lower end
of the pump should be at least 10 feet from the bottom of the
well.
At the time of installation of submersible unit minimum one
check valves always be used. If the pump does not have a built-in
check valve, a line check valve should be installed in the discharge
line within 25 feet of the unit and below the water draw down
level. For deeper settings, more than one check valves may be
required (as per manufacturer’s recommendations).
Internal pump check valves or spring loaded check valves close

quickly and help eliminate water hammer. Check valves are used
to hold pressure in the system when the pump stops. They also
prevent backspin, water hammer and upthrust. Any of these
can lead to early pump or motor failure. Although drilling the
check valves or using drain-back check valves may prevent back
spinning, they create upthrust and water hammer problems.
Following are the main disadvantage of not using a check valve,
leaking check valve, or drilled check valve with submersible
pumps.
• The water in the drop pipe and the water in the system can
flow back in the discharge pipe when the motor stops, this
can cause the pump to rotate in a reverse direction. If the
motor is started while it is backspinning, an excessive force
is placed across the pump-motor assembly that can cause
impeller damage, motor or pump shaft breakage, excessive
bearing wear tear etc,
• The pumpset starts under a zero head condition, this causes
an uplifting or upthrust on the impeller-shaft assembly in
the pump. This upward movement carries across the pump
motor coupling and creates an upthrust condition in the
motor, repeated upthrust can cause premature failure of
both the pump and the motor.
Place the pump on the motor in order that they are positioned
along the same axis and insert the motor shaft in the pump shaft
joint; the coupling must not be forced. Tighten the screws or the
nuts that diagonally fix the pump motor flanges with a driving
torque as quoted in below table.
Motor Type Screw Size Driving Torque Nm
Motor 4 inch M8 18
Motor 6 inch M12 100
Motor 8 inch M16 200
If the pump is already coupled to the delivery piping and you use
a chain pipe wrench, tighten the pump, holding it only by the
delivery opening. The threaded pipes must be connected in such
a way as to support the unscrewing action due to the starting
and stopping of the pump. The thread of the pipe, which has to
be screwed into the pump, should not be longer than the thread
of the pump.
After screwing the pipe into the delivery opening, tighten the
screw assembled to avoid the loosening of the first section of the
pipe. When plastic pipes are used, the pump should be secured
by an unloaded rope to be fastened to the delivery opening.
Use cable tie/clamp every 3 meters to fix the cable to the support
rope or to the delivery pipe. Once the cable has been fastened,
cut off the remaining part of the clip.
If plastic pipes be used, do not stretch the electric cable and the
support rope in order to avoid the tearing of the electric cable
due to the plastic pipes stretch caused by the weight of the water
contained in it.
When flange pipe used, the cable tie/clamp must be positioned
before and after each flange.
Verify that the well is not clogged along its total length. Lower the
pump into the well, paying attention not to damage the electric
cable.
Be extremely careful not to scrape or damage the
submersible power cable, hold the cable up away
from the well casing at the time of lowering.

The dynamic water level must always be above the suction
support of the pump. The pump suction is atleast 3 meter below
the expected drawdwon level. The lower end of the pump should
be at least 3 meter above from the bottom of the well.
Block the delivery pipe with proper hangers on the well head.
Loosen the support rope and fix it to the ground work.
The electrical connections should be carried out by an authorized
electrician according to the regulations in forece. Supply voltage,
current and cosɸ are mentioned on the motor name plate that
has to be kept within the electrical panel.
The motor must be earthed and connected
to the electrical panel.
When the pump has been connected to the power supply,
establish the current direction of rotation as follow.
1. Start the pump and check the head/pressure supplied with
gate valve not completely closed.
2. Stop the pump and interchange two of the phase
connections.
3. Start the pump and repeat the setp 1, with gate valve in the
same position.
4. Stop the pump, compare the results obtained in step 1 and
step 2. The connection, which supplies the highst head/
pressure, is the correct one.
The pump must not be started until the suction
support has been completely submerged.
When the pump has been installed and submerged, it can be
started with the gate valve closed to one third (1/3). If there are
impurities in the water, the gate valve should be opened gradually
until the water becomes clearer. The pump should not be stopped
until the water is completetly clean again, since otherwise the
pump parts and the non-return valve may be damaged.
If the pump flow rate is higher than that of the well, the use of a
protection device against dry operation is recomended. Without
any protection against dry operation, the water level falls under
the suction support and the pump sucks air. In long term, this
causes damages due to poor cooling and lubrication.
The system must be designed to match the flow and pressure
produced by the pump. Systems that allow the pump to operate
at low pressure/high flow conditions cans cause cavitation or upthrust problems and damage the pump or the motor. Systems
that allow the pump to run at high pressure/low flow conditions
(i.e. operating at or very near shutoff) for extended periods of
time can cause the motor to overheat and burn out. A pressure
relief valve should be installed if the pump shutoff pressure
exceeds the pressure rating of the system.
The system must be designed so that the pump is not cycled ON
and OFF excessively.

8.12 Start Up
A submersible pump, properly installed in a clean well, will run
for a long period of time with a minimum of attention. However,
conditions are not always ideal and can change for the worse in the
course of time.
Submersible pump usually run unattended and automatic control
devices are used to stop and start the pumpset and to protect it from
abnormal conditions such as overloads, line faults, etc. It is important
that these automatic devices be adjusted properly and maintained in
good working condition. Failure of these devices can easily cause the
failure of a pump that is in excellent condition. Unfortunately these
protective devices may not protect the installation against all of the
hazards that may be encountered.
In order to assure that potential problems are identified and
corrected as soon as possible, a program for regular inspection and
testing of the unit should be established. The frequency of inspection
and testing will vary depending on the complexity of the controls,
the consequences of a failure, the cost of making the inspections
and tests, the age and condition of the unit, the results of previous
inspections and tests, and the operating philosophy of the owner/
operator.
On a periodic basis, the unit should be given a quick inspection, that
routine inspection should include the following checks.
• Check for any obviously abnormal conditions such as gross
leakage or gross damage.
• Check that the unit is not making excessive noise.
• Check the electric panel for alarms, blown fuses, etc.
• Check the electrical system for signs of overheating or other
abnormal conditions.
Any problems noted should be carefully investigated and corrected
immediately.
Note that a large portion of the probable causes are electrical and also
that a large portion of these electrical problems are due to above ground
equipment. Before going to the time and expense of pulling the unit from
well, be sure that all above ground problems have been corrected and
that a thorough diagnosis has been made indicating that the problem is
underground.
