Abstract
A system for separating particulates from a liquid prior to pumping of the liquid. The system is amenable to use, for example, in a wellbore environment for separating sand or other particulate matter from a production fluid. The system uses a sand separator, a submersible pump and a mechanism for reinjecting the particulate matter downstream of the pump discharge. This permits the sand and other particulates to be routed around the pump to reduce the potentially detrimental effects of such particulate matter on certain pumps.
