Title: Protection of downwell pumps from sand entrained in pumped fluids

Abstract: A separation system for protecting a pump disposed in a well. The separation system separates sand from the well fluid prior to pumping of the well fluid. The separated sand, or other particulates is routed past the pump used in producing the desired well fluid. The sand is then reinjected into the produced fluid stream at a location downstream of the pump.
