4. FUNCTION AND FEATURE
These types of model are suitable with independent floating impellers to provide easy starting and long life automatically adjusting to match pumping conditions for various applications. Heavy duty stainless steel inner and outer cover provides protection and accurate alignment of internal components. High quality shaft bearings provide low friction and high wear resistance. Strong stainless steel shaft ensures positive impeller and longer lasting life.
5. INSTALLATION
Basic
Our motors and pump supplied are already fitted and connected with cables. Parts or accessories are sometimes wrapped individually or fastened to the equipment. If any
damage or losses have been incurred; promptly notify your Prakash pump representative.
Along its entire length the well diameter must be wide enough to allow for passage of the
pump with clearance all round.
Handle the pump carefully; don’t drop it or let it fall. The safe movement of the equipment is on the user responsibility and any lifting operation
must be carried out by suitable trained and qualified personnel only.
Pump installation
Before installation, must check whether the cable is damaged, scratched, broken, etc. If they
are faulty, must consult Prakash pump representative.
The pumps are normally supplied with motor and pump disconnected; connect the coupling
and pump-motor suction lantern.
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
While installing the motor pump, avoid impact, rubbing or anything else that can damage the power cable or puncture the cable leading to short-circuit.
Direction of rotation The direction of rotation is clockwise,
Rotation speed
All the models are suitable for speed of 2900 rpm.

7. CONDITION OF USAGE
FAULT
POSSIBLE CAUSES
REMEDIES
Pump does not
start
Too low voltage; Impeller blocked; Stator winding burn up;
Capacitor damaged; in case of
single phase motor.
Absent phase; in 3phase or
single phasing
Too large resistance of cable
Adjust voltage to ±10% of the rated;
the shaft at the fan side to remove the sundries;
Repair; Replace capacitor; Check switch and cable connection etc; Check 3phase power. Use the proper cable;
Pump delivers
insufficient water
or no water
Highly delivery head;
The water level is low. Air locked; Pump worn off; Wrong rotation.
Lower the head; Throttle pump output or reset pump at
lower depth if possible.
Normal delivery may resume if pump is
started and stopped at one minute interval;
Replace pump or repair;
Inverse two phases in 3 phase.
For clean or slightly dirty water with maximum sand contents: 50 g/m³. Water temperature up to 35°C.Transfer medium: Clean cold water at ambient temperature 40°C.Pump should be submersed before starting. Minimum internal diameter of well: 4’ / 100mm.
8. MAINTENANCE
Often check cable and duly replace the cable if it is found with fault of furcated. Absorbed current and head supplied by the pump must be checked at regular intervals. This procedure should be carried out frequently when water contains considerable quantities
of sand.
In the case of emergency systems, it is advisable to operate the pumps once a month in order
to avoid the risk of blocking.
Run the pump at a sequence time as recommended.
