Service and Repair
Removing the Extracta Assembly
Disconnect, lock out, and tag power at the panel before servicing the pump
When servicing equipment, use non-sparking tools and use caution when removing or
installing equipment to avoid generating a spark.
The Discharge Head attached to the Extracta Assembly has a mechanical interlocking dowel
mating with the Red Jacket manufactured Submersible Pump Motor Assembly. Competitive
units are no longer compatible with the Maxxum® Extracta Assembly.
Only Pump Motor Assemblies listed in Table 10 are compatible with the Maxxum® Pump. These
are marked with an “FM” on the nameplate (Figure 15).
1. If a ball valve is installed down line from the pump, close it.
2. Unscrew the 5/8-inch bolt and pull the yoke up and rotate it 90° counterclockwise (see Figure 15).
3. Remove the protective cover from the Pressurstat. Rotate the adjustment screw counterclockwise to relieve pressure in
the packer/manifold assembly.
4. Unscrew and remove the four 1/2-inch Extracta retaining bolts.
Confirm that the lifting eyebolts are properly 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 extractable and the eyebolt. If corrosion has occurred,
the extractable and eyebolt should be replaced.
5. Utilize BOTH lifting eyebolts to suspend the pump vertically. A vertical lift will ensure that the o-ring in the
manifold will not be damaged. Remove the pumping 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.
