Preparation of Pump set for installation
In order to avoid transit damage, motor and pump are supplied
in uncoupled condition. They are to be coupled at site, as
describe below
• Keep the motor, duly filled with water as per 3.3.1, vertically
on the ground.
• Couple the pump & motor shaft by a coupling. (use strong
crane / chain pulley block / hoist or any other similar lifting
device to lift the pump).
• Lock the coupling on the motor shaft with the help of grub
screw provided along with the coupling. (for 4" motor + 6"
pump combination, this is not required).
• Couple the pump and motor with the help of four studs and
nut provided on the top face of motor.
• Check free rotation of coupling / rotor.
• Fit the strainer on Suction casing.
• Pass the cable through cable protection pipe.
The pump set is now ready for installation.
4.0 Vertical installation
Before installing the pumpset in the bore well, it is recommended
to check the trueness of the borewell throughout its depth by
pattern. (Pattern: A piece of pipe of overall length and diameter
equal to the max diameter of the pumpset). A slight inclination
of the well is immaterial so long as the clearance is sufficient
for the pumpset to lower easily into the bore, but any twist or
bend can make installation difficult or even impossible.
