Abstract
The invention relates to a cleaning unit for power driven pumps which are required to pump fluids containing significant quantities of particulate material of greater spcific gravity than the fluid. A portion of the pressured fluid output of the pump is utilized to drive a fluid motor which in turn rotatably drives a centrifugal separator. The separator has its inlet connected to the source of particulate containing fluid and effects the centrifugal separation of such fluid into two streams, respectively a clean fluid stream and a particulate containing stream. Means are provided for discharging the particulate containing stream and a diffuser means is provided for converting the rotational energy in the clean fluid stream into a pressure head which is employed to transfer the clean fluid to the inlet of the pump.
