4" Standard Pump Installation, Operation & Service Manual
Replacing The Quad Seal
When servicing unit 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. If an electronic line leak detection transducer is installed, it must be removed from the leak detector port
following instructions in the appropriate Line Leak installation manual (see Figure 32). A mechanical line leak
detector does not need to be removed.
3. Back out the electrical yoke disconnect bolt (see Figure 28 on page 33).
4. Swing the electrical connector aside.
5. If a siphon system is in place, disconnect the siphon tubing. If ball valves are installed, close them.
6. Remove the two lock-down bolts. To relieve pressure, rock the pump to allow excess pressure to flow into the
tank or back out pressure adjustment screw (see Figure 24 on page 28). \
Confirm that the packer wiring compartment cover/plug (with lifting eye bolt) is
properly torqued at 50 ft-lbs (70 N•m). Confirm that the lifting eye bolt is properly
torqued to 10 ft-lbs (13.6 N•m) with a minimum of 6 full threads installed.
Occasionally, eye bolts are removed after pump installation and corrosion may occur
in the threaded areas of the wiring compartment cover/plug and the eye bolt. If
corrosion has occurred, the cover/plug and eye bolt should be replaced.
7. Utilize the lifting eye bolt 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 portion
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.
8. Lift out the extractable unit.
DO NOT damage the surface above the manifold's discharge port. The quad seal
below the packer's leak detector port seals on this surface.
Disconnect, lock out, and tag power at the panel before servicing the
pump.
