3.1.1 Installation of support bracket & bend –
Before installing the pump, ensure that sump bottom is flat and leveled. The support bracket &
bend should be attached and fixed to the sump bottom with foundation bolts, so that the guide pipe
shall be exactly vertical.
Ensure that support bracket and bend are located correctly relative to descending pump vertical
guide pipe and discharge pipe.
3.1.2 Lowering the pump - Attach the guide shoe & guide pipe adapter to the pump. The unsupported
length of guide pipe should not exceed 6 m.
3.1.3 Fix the guide pipe in the support bracket and locate the vertical position of guide pipe holder at the
top of the pit. Now grout the guide pipe holder.
3.1.4 Insert the above assembly in the guide pipe by dismantling the guide pipe holder & refit the holder
in the guide pipe.
3.1.5 Check- Lower the pump with the help of chain. While sliding over the guide pipe into the sump,
check that the cable is not slagging and is not under tension.
3.1.6 Ensure that the pump position is exactly vertical on the support bracket. Check by giving a jerk.
3.1.7 Before taking the pumping station into use, check that there are no loose solid pieces or other
material on bottom of sump that would damage the pump.
3.1.8 DO NOT LIFT THE PUMP WITH THE HELP OF CABLES.
3.2 The NS pumps supplied for portable installation requires no foundation. Only ensure that the
delivery pipe line is well supported and its weight is not acting on pump casing directly.
3.3 Use chain with intermediate hooks for holding to lower or lift the pump. This type of chain is specially
designed to avoid the tendency of the operator to lift the pump with the help of cable causing
damage & replacement of the cable unit. While selecting size of the chain, refer weight of the pump
given in 7.6. and chain capacity as per chart in 3.4. We recommend use of non-return valve in

3.4 As per IS: 2429 the following sizes of chains can be used upto the weight as mentioned in the
below chart.
4. OPERATION:
4.1 Prior to commissioning of the pump, check the following.
FILL THE OIL INSIDE THE MECHANICAL SEAL HOUSING WITH PROPER GRADE REFER CHART IN
7.5 OF CLEAN OIL FREE FROM MOISTURE. ENSURE THE MECHANICAL SEAL HOUSING OF THE
PUMP IS DULY FILLED AS PER CHART IN 7.6. CHECK THE OIL PLUG OF THE MECHANICAL SEAL
HOUSING IS INTACT.
4.1.1 Check the insulation resistance of winding by using 500 V megger. The insulation resistance of
winding should not be less than 10 mega-ohms for motor rating upto 45kW and 50 mega-ohms
beyond 45kW at phase to phase and phase to Earth. This test should be carried out at free end of
the cable. If the insulation resistance is found less than mentioned above then please consult our
service personnel.
For continuity test, connect the two wires of megger between the two ends of the same phase of
motor. It should show zero resistance. This test should be carried out for the phases.
The resistance across two moisture sensing wires M1 and M2 should be above 5 MΩ. Make sure
to remove control cable connections from terminal board [M1 and M2] before testing this. If the
resistance found less, please consult our service department. The megger test for phase to phase
and phase to Earth should be conducted serially. The megger test should show insulation
resistance above 10 MΩfor motor rating upto 45kW and 50 MΩbeyond 45kW .
4.1.2 The control panel is provided with auto/manual switch. When the switch is on "Manual" position the
pumpset can be started manually by the start push button provided the liquid level is above the low
level electrode. If the switch is on "Auto" position it will start automatically if liquid level in the sump,
is above the high-level electrode. The pump set gets switched off automatically for any position of
Auto Manual switch if liquid level goes down just below the low-level electrode. This is indicated by
glowing of red lamp on control panel.
When the pumped liquid gets mixed up with the oil in the casing cover, it is indicated by glowing of
red lamp under name plate contamination. After rectification of the fault, resetting switch is to be
pressed first and then the pump set will get started by pressing "Starting switch" if it is operated on
"Manual position" or automatically if control panel is operating on "Auto position".
Before change over from star to delta connection, time delay should be sufficient to allow the motor
to attain its normal running speed. The same depends upon the load of the motor and it is generally
around 10 second.
4.1.3 LIQUID LEVEL CONTROLLERS ARE INCORPORATED IN THE PANEL TO PROTECT THE
PUMP FROM DRY RUNNING. THE LOW-LEVEL ELECTRODE SHOULD BE POSITIONED IN
SUCH A MANNER THAT LOWEST END OF ELECTRODE REMAINS ABOVE MOTOR BODY. IF
LOW LEVEL ELECTRODE IS NOT INSTALLED PROPERLY THE MOTOR BODY IS LIKELY TO
BE HEATED UP AS COOLING OF MOTOR IS DONE BY LIQUID IN THE SUMP AROUND THE
STATOR HOUSING. HENCE SUBMERGENCE UPTO FULL CORE LENGTH OF MOTOR IS
REQUIRED.

4.1.5 Hoist up the pump and momentarily switch on the power. If the connections are correctly made the
pump should jerk in anticlockwise direction when viewed from top. If the pump jerks in opposite
direction, change two phases of the incoming leads to the control panel. In no case the direction of
rotation should be changed by changing the leads of motor terminals. Do not run the pump dry.
Just check in which direction the pump jerks.
4.2 While putting the pump in operation, follow the procedure outlined below.
4.2.1 Start the pump. Let the motor pick-up its full speed.
4.2.2 Open the discharge valve slowly.
4.3 Check during running that –
4.3.1 The pump is running smooth.
4.3.2 Power consumption is within limit.
4.3.3 Head and capacity developed by the pump is as specified.
4.3.4 Stop the pump immediately if any defects are detected and must not be started unless they
are rectified. Report immediately to the supplier if it is not possible to rectify the defect.
4.4 STOPPING THE PUMP:
4.4.1 Pump should be switched off only after closing the delivery sluice valve.
5. MAINTENANCE:
Preventive maintenance schedule is the periodical checks and precautions by which possibilities
of failure and break-downs are minimized.
5.1 Daily checks –
5.1.1 An hourly record of the delivery pressure and power input to the pump should be maintained.
5.1.2 Noise and vibrations is the first sign of impending troubles like bearing failure, choking of impeller
or casing and such other operating troubles. The pump performance should be checked for noise
and vibration.
5.2 Periodical checks –
5.2.1 The lubrication of mechanical seals should be checked. The lubricant might get contaminated with
foreign material or get blackened due to overheating. In such cases, oil chamber should be flushed
and filled with fresh oil. Before filling, heat the oil [Servo system 317] to 140°C. This is required to
remove moisture present in the oil.
5.2.2 THE ELECTRODES/FLOAT SWITCHES SHOULD BE CLEANED WHENEVER POSSIBLE BUT
NOT LATER THAN 15 DAYS FOR SMOOTH WORKING OF PUMP.
5.2.3 Clean the sump if there are chances of deposition of the contents of liquid handled.
5.2.4 Replace the Oil from pump periodically after 2000 hrs.
5.3 Annual checks [after one year minimum] –
5.3.1 The pump portion of the motor pump set should be overhauled completely to check the clearance
and to replace the worn-out parts. Clearance between impeller and casing ring and casing cover
are very important.
5.3.2 The effect of liquid handled on pump components should be checked. If abnormal corrosion,
erosion is observed then the components should be replaced with that of suitable material.

vi) Place the unit on skids, pallets or shoring higher than 5 inches from the ground for good air
circulation.
vii) Maintain an even temperature of 15 degree Celsius or higher above the dew point.
6.2 Pump long term storage requirements (Above 3 months)
Submersible units require proper preparation for storage and regular maintenance during storage.
The unit is considered in storage when it has been delivered to the job site and is awaiting
installation.
6.2.1 Storage preparation
i) Although this is a submersible pump, storage in a clean, dry area will help preserve the paint
and prevent corrosion. Hand rotation of the shaft every fifteen days is recommended to keep
the seals free and the bearings lubricated.
ii) Spray oil inside the pump housing, paying special attention to the area around the impeller
wear ring. Spray oil through inlet and outlet flanges of pump. It is then recommended to cover
the flanges with plastic caps or similar.
iii) Take care of all indoor storage requirements.
iv) Use weather-proof coverings such as flame-resistant sheeting or tarpaulins.
v) Tie coverings down to protect the pump from wind damage.
vi) Place the unit on skids, pallets or shoring higher than 5 inches from the ground for good air
circulation.
vii) Maintain an even temperature of 15 degree Celsius or higher above the dew point.
6.3 Site condition before installation of pump:
Pit in which pump is to be installed should be clean, free from hard particles such as nails, cement/
sand particles etc. Submersible pumps are designed only to handle the soft particles such as
clothes, plastic bags, etc.
6.4 Measures for prolonged shut down periods
i) The pump remains installed ready for operation when required.
ii) To maintain pump availability, the pump should be started for 10 second, once in every week.
iii) Always keep cable ends out of the sump to avoid leakage through cable ends to pump.
6.5 The pump is dismantled and stored
i) Prior to storage the pump should be checked and maintained in accordance operator must
ensure that all maintenance, inspection and repair work is carried out by qualified, authorized
staff who are familiar with the equipment and who have read the operating instructions.
ii) O-ring need to change after dismantling the pump. Do not use old O-rings for reassembly of
the pumps.
6.6 Rubber components storage ideal conditions
If the pumps are stored in below conditions, rubber components shelf life should be of 5 years
otherwise all rubber components need to be replaced after 1 year.
Condition:
a. store in cool, dry place with temperature below 15 degree Celsius.
