A double-suction pump with a short bearing span comprises a pump shell, a pump shaft is arranged in the pump shell in a penetrating mode, an impeller is installed on the pump shaft through a key block, a sealing ring is arranged between the impeller and the pump shell, a shaft sleeve and a bearing are sequentially installed on the two sides of the pump shaft, bearing installation openings are machined in the two sides of a shell body of the pump shell, and the bearing is located in the bearing installation openings. A bearing gland is mounted at the non-driving end of the pump shell, a mechanical seal gland is mounted at the driving end of the pump shell, and a mechanical seal is mounted in the mechanical seal gland and positioned by a positioning ring mounted on the pump shaft. The bearing span is small, the bearing stress is small, the service life is long, and the water pump runs more stably; the structure is simple, compared with a conventional structure, one mechanical seal is omitted, the pump boundary
