1. GENERAL
The booklet covers instructions for following models of submersible pump.
This model is suitable for domestic water supply, sprinkler, Garden water application,
pressure boosting from deep well, etc.
The complete range of Submersible pumps is covered by three driving units’ there by
reducing inventory and achieving interchangeability of parts.
Pumps when properly installed and given due care in operation and maintenance should
operate satisfactorily for a long period.
All the pumps and motor are carefully installed and tested in our factory, so as to ensure the
performance and features given in our catalogues.
Regular operation of the equipment depends on its being used correctly and serviced
periodically or regularly by our authorized service center.

Clean the surface to be coupled.
Put the suction lantern of the pump in correspondence of the motor studs.
Couple the grooved joint of the pump to the motor shaft.
Screw in the nuts to the suction lantern, and then fix the crosswise starting from the one
opposed to the cable.
The torque recommended is 10 Nm for 4’ motor.
Connect the cable to the pump with the cable guard and place the filter on the suction lantern.
When threaded connections are used, delivery pipes must be tightened to avoid any risks of
the pump falling into the well.
A safety rope or chain on non-perishable material should always be used to secure the pump.
Attach the power cables to the delivery pipe with cable clamps placed at intervals of
approximate 3 meter.
Lower the pump into the well, making sure the feed cables are not damaged in any way during
the operation.
Install the pump with its axis placed at least 0.5 meter above the bottom of the well.
Power supply
Note:
All work of an electrical system must be carefully carried out by skilled person only.
Make sure the frequency and mains voltage correspond with the name plate data.
Check whether the power supply is conformed to the stipulation of name plate before
installation.
Power supply connected with the pump must be assembled with ELCB, and the voltage
fluctuation must be controlled within ± 10% of rated.
For connection of cables in the well, use thermo-shrinking insulation sheathes or other
system used for submerged cables.
The operating temperature limiting the drop in voltage to at most 3%.
The live wire should made dead before making the connection.
The connection between the pump and the other part must be made using suitable material
for submersed cables and in compliance with the current regulation from local electricity
board authority.
All checking of connection should be checked by appropriate instruments.
Important
