APPENDIX A – ASSEMBLY OF
PUMP AND MOTOR
Most of the time, the pump and the motor are
shipped separately in two different boxes. They
need to be assembled together in the field prior to
being installed in the well. For the short pump
(lease than 5 stages), the motor and pump may
be assembled together on the ground horizontally.
If the pump is over 6 stages long, it is recom-
mended to assemble them in the vertical position.
1. Check that the pump shaft and the motor
shaft turn freely.
2. Clean the flange faces and the registers on
the pump and the motor. Remove all burrs
from these areas. Clean the exposed portion
of the pump shaft and motor shaft. If the
pump is supplied with the coupling assembled
on the shaft, clean the inside of the motor-
end of the coupling.
3. Install the key on the motor shaft, if it is not
the splined shaft.
4. If the shaft coupling has setscrews in the
motor half of the coupling, loosen or remove
these setscrews.
5. Align the motor with the pump and slide the
motor shaft into the shaft coupling on the
pump until the shaft butts. Make sure the
motor shaft lifts the pump shaft by 1/8" to
1/4". (for enclosed impeller only) Be careful
not to damage the shaft, the coupling or the
key. Orient the motor so that the motor leads
are aligned with the notch provided in the
pump’s mounting flange. If the shaft coupling
has setscrews in the motor half the coupling,
install and tighten the setscrews.
6. Install and tighten the mounting bolts (or cap-
screws) on the flange.
7. Untie the cableguard on the pump and re-
assemble it with the motor leads under the
cableguard to prevent damaging the leads
when lower the pump into the well.
Appendix B – SPLICING POWER
CABLE TO MOTOR LEADS
A waterproof splice must be made to connect the
power cable to the motor leads. A properly made
splice will last the life of the pump. An improperly
made splice will become a service problem. In the
market, there are different materials and methods
to make water proof cable splices.
For example: by waterproof tapes
by resin castings
by heat shrink tubes
All of these system are well-known and field-
proven for many years. It is installer’s decision to
choose one of the systems available. Following
are the procedures for waterproof tapes and resin
castings splices:
Taped Cable Splice:
1. Strip the insulation of each conductor of the
power cable back enough to allow the con-
ductor to extend half way through a sleeve
type connector. Crimp connector to the con-
ductor. Strip the insulation of the motor lead
same as the power cable. Fit it into the con-
nector and butt against cable end. Crimp
connector as before. Pull on wire to make
sure connector is firmly crimped to both the
motor lead and the power cable. Scrape the
insulation to move any loose bits of tape or
thread and roughen surface. Thoroughly
clean surface with solvent. This will insure a
watertight splice.
2. Tape individual joints with rubber electrical tape
start at the center of the connector, and tape 2
inches past the end of conductor insulation
end. Stretching tape about 10% while taping.
Overlap tapes about one half of tape width.
Make two layers. The end of 2nd layer should
be 2 inches beyond the end of the first layer.
3. Tape over the rubber electrical tape with #33
Scotch electrical tape or equivalent, using two
layers as in step #2 and making each layer
overlap the end of the preceding layer by
2 inches.
Cast Cable Splice:
1. To prepare the 3-conductor power cable for
splicing, insert a sharp knife blade between
the cable jacket and lead insulation and strip
the jacket back 2.5” from the end. Taking care
not to cut the lead insulation. Strip the cam-
bric wrapping (if any) off the conductors and
strip back rubber insulation 5/8” from the end.
Assemble the cable connectors and crimp
them in place using a crimping tool.
2. Cut off the motor leads to equal length. Clean
off the ends of the leads for about a foot,
using a cloth wet with gasoline or solvent.
Clean the end of the power cable also. Insert
