ABSTRACT:
This invention is a packer which is a short pipe designed to attach to a screen or filter device at one end. The other end is designed to attach to the well pipe or nipple extension or provide a seat for a submersable pump. On the outside of the pipe are four annular rings to provide a seal between the packer and the adjacent strata of earth or pipe casing. Three of the four annular rings extend perpendicular from the pipe. The fourth which attaches to the end of the packer extends in an upwardly concave fashion from the short pipe. On the inside of the packer is an annular ridge in approximately the middle of the short pipe. This ridge keeps the well pipe, nipple extension, submersable pump, and the screen from touching when they are attached to the packer. The packer is made of plastic and can be cast in a single step process.
