7 Pump Disassembly and Reassembly
7.1 Pump Disassembly
NOTICE:
Pump shall not be operated outside of the preferred operating range except during startup. Do
not operate pump below recommended minimum flow as severe damage may occur.
NOTICE:
Pump components should be match marked prior to disassembly.
1. Clear a large area adjacent to the pump as a storage space for pump parts as they are disassem-
bled. If the pump has a long column arrange parallel timbers on the ground to support the pump
column horizontally. After disassembly for repair or replacement of pump components, reassemble
in all cases in the reverse order of disassembly.
2. It is recommended that maintenance personnel become thoroughly familiar with the VIS pump be-
fore performing any removal of the components. Consult the manufacturer's instructions for detailed
disassembly information for the prime mover.
a) Remove the electrical connection at the conduit box and tag electrical leads at the motor.
NOTICE:
Before opening the conduit box of an electrical motor, be sure that the current to the motor
is shut off. Severe injury to personnel could result if contact with live motor leads is made.
NOTICE:
Match-mark parts in sequence of disassembly to aid in the reassembly procedure.
b) Disconnect the discharge piping from discharge elbow.
NOTICE:
Do not work under a heavy suspended object unless there is a positive support under it which
will protect personnel should a hoist or sling fail.
3. In the following pump disassembly procedures references are made to installation sections of this
manual, these sections will aid in the disassembly of the pump.
a) Disconnect discharge elbow and begin removal of column sections. Refer to 5.6 Lowering
Pump into Well on page 19 .
b) For removal of bowl assembly and motor, hoist the bowl assembly from the well, using elevator
clamps. Hoist in the same manner as for the column 5.6 Lowering Pump into Well on page 19 .
