A screw pump (1) comprises a body (2) which has a cylindrical duct (12) formed therein. A screw shaft (10) is located in the cylindrical duct (12) and is arranged to transport liquid between an inlet (18) and an outlet (20) of the screw pump (1). The screw shaft (10) has a screw thread (11) which defines a helical liquid path (16) within the cylindrical duct (12). The body (2) of the screw pump (1) includes a groove (26) extending along an inside surface (12a) of the cylindrical duct (12), the groove (26) defining, in part, a ball-passage (24) which extends alongside the screw shaft (10) and intersects with the helical liquid path (16). The ball-passage (24) contains a plurality of balls (22) which are guided along the ball-passage (24) by the screw thread (11) when the screw shaft (10) rotates relative to the body (2).
