That is a pitless adapter. If there is a hole in the top of it, you screw a piece of 1" pipe in it with a tee handle on it to pull the pump but... It may be too heavy depending on the depth and size of the pump and drop pipe material.
If you lift it, since you say PVC, you must hold the weight while you unscrew the sections of pipe as they come up. If it is galvanized, you need a pulling machine or derrick truck usually. If it is PE pipe, you lay it on the ground away from the well.
Pulling a submersible pump can be a character building experience.
