ABSTRACT:
An apparatus for raising and lowering a submersible pump in a well. A cylindrical drum for reeling flexible water pipe is mounted for rotation at one side of the well. A cavity is provided in the drum for accommodating connectors or other large items at the top of the well, and a guide is provided at the top of the well for guiding water pipe vertically from the well and substantially horizontally to the cylindrical drum. An electric drive is provided for rotating the drum, the drive being mounted to accommodate sudden stopping of the drum due to jamming of the submersible pump or the water pipe secured to the pump as the pump is being withdrawn from the well.
