Replacing the UMP

WARNING
When servicing unit use non-sparking tools and use caution when removing or installing equip-
ment to avoid generating a spark.

Kits Required:

• UMP replacement kit (P/N 144-327-4)
• Hardware/seal kit (P/N 410154-001)
• Die Spring kit (P/N 410485-001

Procedure:

1. If a ball valve is installed down line from the pump, close it.
2. Remove the two extractable lock-down nuts (see Figure 22). The springs on the lock-down studs between the
extractable's flange and the manifold will push the extractable up, breaking the seals.
Confirm that the packer wiring compartment cover (with lifting eyebolt) is properly
WARNING
torqued to 10 ft-lbs (13.6 N•m) with a minimum of 6 full threads installed.
Occasionally, eyebolts are removed after pump installation and corrosion may occur
in the threaded areas of the wiring compartment cover (eyebolt plug) and the
eyebolt. If corrosion has occurred, the cover and eyebolt should be replaced.
3. Utilize the lifting eyebolt to lift out the extractable unit and place it on a clean surface. Removal of the
extractable section of the pump must be conducted with caution. Make certain that the extractable
section remains centered within the riser pipe and that no portion of the extractable binds during the removal
process. If binding occurs during removal, stop and determine the cause of the binding and correct the
situation before proceeding with removal.
4. Remove the old UMP by removing the four bolts holding the discharge head as shown in Figure 23. Discard
the old gasket and fasteners.
Disconnect, lock out, and tag power at the panel before starting to
