The utility model relates to the technical field of mechanical sealing of slurry pumps, and discloses a leakage-free dry oil lubrication slurry pump which comprises a bracket assembly, a rotating shaft is rotationally connected in the bracket assembly, a shaft sleeve is rotationally connected to the outer surface of the rotating shaft, and a shaft sealing mechanism is rotationally connected to the outer surface of the shaft sleeve. According to the leakage-free dry oil lubrication slurry pump, the first filler and the second filler are installed on the two sides of the first rotating shaft lip-shaped sealing ring and the two sides of the second rotating shaft lip-shaped sealing ring correspondingly, and therefore oil is effectively prevented from entering slurry or leaking out of the filler rings; meanwhile, granular slurry in the pump body is also prevented from entering the first rotating shaft lip sealing ring to cause abrasion to the first rotating shaft lip sealing ring and further cause damage to the ro
