The pump comprises a motor having a shaft (4) supported by bearings (3) and having an impeller (6) mounted at each end of the shaft. Conduit means (10) connect the discharge branch (8) of one pump casing (7) to the suction branch (9) of the other pump casing (7). In use, a number of the pump units can operate in series by connecting an outlet (13) of one unit to an inlet (14) of the next unit. The pump can be used to pump slurry, acid or air and may be driven electrically, hydraulically or by a turbine. By mounting the impellers at each end of the shaft, axial thrust loads are balanced. <IMAGE> |
