摘要： A single-shaft multistage pump is provided to make small-sized and space-saved possible. The single-shaft multistage pump includes a rotary shaft (1) on which impellers (2) are disposed at multiple stages, bearings (31) and (43) for supporting the rotary shaft, and a balance device (8) adapted to apply, to the rotary shaft, a balance thrust force opposing an impeller thrust force. A water-lubricated bearing is used as each of the radial bearings, and the rotary shaft is supported by the water-lubricated bearings with a balance member (21) of the balance device interposed therebetween.
