PCT No. PCT/AU95/00532 Sec. 371 Date Mar. 28, 1997 Sec. 102(e) Date Mar. 28, 1997 PCT Filed Aug. 25, 1995 PCT Pub. No. WO96/06999 PCT Pub. Date Mar. 7, 1996An apparatus for generating water currents in a swimming pool is provided in which an intake chamber, a discharge channel and a pump impeller are contained within a common housing. The discharge channel is defined within an open-ended discharge tube which extends longitudinally within the cylindrical housing. In use, the pump operates to suck water into the intake chamber around the tube through the front end of the housing. The water flows around the rear end of the discharge tube into the discharge chamber where it is expelled forcibly into the swimming pool through the discharge outlet at the open front end of the discharge tube. A pump stator member with radially extending guide vanes is provided in the discharge tube in front of the impeller to reduce swirling in the discharge channel. A safety guard may be provided over the inlet and the outlet at the front end of the housing.
