A gas spiral housing ( ) has a gas spiral ( ) at its lower end positioned beneath a plurality of perforations ( ) in tubular member ( ). A solid spiral ( ) is positioned below upper gas spiral ( ) and a swirl chamber ( ) is provided between gas spiral ( ) and solids spiral ( ). Gas separated by gas spiral ( ) flows upwardly in inner gas annulus ( ) to gas reservoir ( ) for discharge by ball check valve ( ). The solids are separated by solids spiral ( ) and the clean liquid after the gas and solids have been separated flows upwardly in flow tube ( ) and pipe string ( ) from lower swirl chamber ( ). An embodiment shown in FIG. provides a shroud ( A) about a downhole motor ( A) to effect cooling of motor ( A).
