A cleaning system for cleaning tubing using cleaning balls ( 20 ) circulated with the fluid through tubing ( 8 ). The system includes a separator ( 12 ) having a perforated funnel, which permits the fluid, but not the cleaning balls ( 20 ), to pass through. A housing ( 21 ) having an apertured partition ( 28 ) is used to divide the housing ( 21 ) into an first compartment ( 19 ) and a second compartment ( 27 ). An entrance ( 2 ) of a fluid supply pipe ( 23 ) and an exit ( 3 ) of a ball supply pipe ( 24 ) are formed for creating a difference in pressure to create a suction force to recirculate the cleaning balls ( 20 ) from the housing ( 21 ) via the ball supply pipe ( 24 ), back to the tubing ( 8 ) for cleaning the walls of the tubing ( 8 ). An entrance ( 13 ) of a ball return pipe ( 17 ) and an exit ( 14 ) of a fluid return pipe ( 16 ) are formed for creating a difference in pressure to create a suction force to recirculate the cleaning balls ( 20 ) from the separator ( 12 ) via the ball return pipe ( 17 ), into the housing ( 21 ).
