Installing the Extracta Assembly (Ref. Figure 15)
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. Replace the lower o-ring (see Figure 20, Item #4) in the manifold and the one in the lower face of the Extracta
head (see Figure 20, Item #3).
2. Sparingly lubricate the lower o-ring located in the inside the manifold and the o-ring in the lower face of the
Extracta head. Use light grease, oil, or petroleum jelly.
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.
3. Utilize BOTH lifting eyebolts to suspend the pump vertically. Lower the Extracta into position through the
manifold assembly. Care should be taken to keep the unit as near to vertical as possible to avoid damaging the
o-rings. Start the four 1/2 inch Extracta retaining bolts. DO NOT TIGHTEN THEM AT THIS TIME.
4. Rotate the yoke-disconnect into position so that the brass boss aligns with the disconnect port in the packer
assembly.
5. Tighten the 5/8 inch bolt to fully engage the yoke.
6. Torque the four 1/2 inch Extracta retaining bolts to 50 ft lbs.(68 N•m).
7. Torque the 5/8 inch bolt to 50 ft lbs.(68 N•m).
8. Rotate the adjustment screw on the Pressurstat to reset line relief pressure.
9. Lubricate the o-ring on the Pressurstat with petroleum jelly and install the protective cover by rotating it until it
contacts the Pressurstat body. Hand tightening is sufficient, as the o-ring completes the seal.
10. Visually inspect the pumping unit for leaks while the pump is running. This is to ensure that no seals or sealing
surfaces were damaged during removal or installation of the Extracta assembly.
