3. DISASSEMBLY/ASSEMBLY WET END
To disassemble the Roto-Jet pump, refer to the figures in Section 2.5 and 2.6. The following
instructions are applicable to the pump being removed from its foundation and placed securely
into a vertical position in which the pump shaft is vertical and the manifold is facing upward.
WARNING:
Before lifting the pump into the vertical position first remove the lifting eye and
install swivel hoist. When tightening the swivel hoist ring, torque to 100ft-lbs. Once the pump
is re-assembled and in the horizontal position remove the swivel hoist and re-install the lifting
eye. Reference APPENDIX A Drawing.
3.1 PREPARATION FOR DISASSEMBLY
(1)
Disconnect the motor, lockout and tag.
(2)
Block off the suction and discharge.
(3)
Disconnect and remove all piping from the manifold.
3.2 CAUTIONS
The following precautions are recommended to insure satisfactory pump operation after
assembly.
Replace any o-rings that are exposed during the pump disassembly process as they lose their
seal integrity and may leak.
Be sure all parts are free of dirt, stray metal chips, or any foreign matter and have been
thoroughly cleaned.
All torque values given assume lubrication with anti-seize on threads and underside of cap
screw heads (except the pick-up tube nut). Refer to section 2.5 for torque values.
All three bearings should be replaced as a set.
To avoid creating an out of balance condition that makes the pump susceptible to vibration
damage, match mark cap screws and rotor cover relative positions for reassembly into the
same positions.
