ABSTRACT:
In a pumping installation having an above-ground prime mover driving an axial-flow pump below through a relatively long drive shaft unit, the drive shaft unit is coupled to the pump shaft through a sliding coupling which accommodates axial expansion and contraction of the relatively long drive shaft unit due to temperature changes. The pump shaft is provided with combined rotational and axial thrust bearings for taking up axial thrusts in either direction, and an improved shaft seal is provided for the pump shaft.
