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.
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 19).
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 in-
stallation 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.
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
