4.4 Installation
4.4.1 Safety instructions
DANGER
Before starting any installation work
or removing any parts of the pump-
ing unit, read Chapter 1.6 "Safety",
Page 6.
Tighten all screws in accordance
with Chapter 12.3 "Tightening
torques".
4.4.2 Sequence of installation
Perform the installation in the following order:
1. Prepare installation site, see Chapter 4.4.3,
Page 23.
2. Arrange components for installation, see
Chapter 4.4.4, Page 24.
3. Inspect components, see Chapter 4.4.5,
Page 25.
4. Install motor, see Chapter 4.4.6, Page 26.
5. Install coupling, see Chapter 4.4.7, Page 27.
6. Install pump bowl assembly, see Chap-
ter 4.4.8, Page 30.
7. Install impeller, see Chapter 4.4.9, Page 32.
8. Vent motor, see Chapter 4.4.10, Page 33.
9. Install power cable, see Chapter 4.4.11,
Page 35.
10. Fasten the power cable to the cable guard,
see Chapter 4.4.12, Page 39.
11. Install riser pipe, fasten power cable to riser
pipe, see Chapter 4.4.13, Page 40.
12. Connect power cable to terminal box, see
Chapter 4.4.14, Page 43.
13. Connect terminal box to main power supply,
see Chapter 4.4.15, Page 43.
4.4.3 Prepare installation site
1. Verify that the wellhead foundation is poured
and cured, if made of concrete.
The total load on the wellhead foundation will
consist of the motor, pump bowl assembly,
riser pipe (full of water), wellhead assembly
and power cable. See Chapter 12.2 "Data
sheet", for weights.
2. Verify that open discharge run-off, ditch, etc.
for flushing out well and testing unit is pro-
vided for.
3. Verify that a log of the well recording depth,
straightness, casing variations, standing water
level, rated capacity, pumping level, etc., is at
the installation site.
4. Ensure that the well diameter is large enough
down to the installation depth so that the
pumping unit can be fitted without difficulties.
See Chapter 3.4.1 "Survey of well", Page 16.
5. Check the dependability of auxiliary equip-
ment, particularly of hoists.
6. Compare the information in Chapter 12.2
"Data sheet" with that on the rating plate on
the motor.
7. Ensure that the line voltage (measured be-
tween two phases) is equal to the motor volt-
age according to the rating plate.
The maximum permissible voltage fluctuation
is given in Chapter 12.2 "Data sheet".
Greater voltage and frequency fluctuations
must be reported to Flowserve and be con-
firmed by Flowserve in written. In case of
doubt, ask Flowserve before starting up the
pumping unit.
8. Measure the insulating resistance of the motor
according to Chapter 6.8.1 "Insulation test",
Page 53.
CAUTION If the ascending riser pipe is made
of flanged pipes, the flanges must
have recesses for the power cable if
the well diameter is narrowly pro-
portioned.
