PROBLEM TO BE SOLVED: To provide a non-leakage pump capable of transferring even a fluid to be flowed with non-leakage and high slurry density. SOLUTION: There is provided a magnetic non-leakage pump 1 whose rotating shaft 18 rotates by magnetic force. In the magnetic non-leakage pump 1, a portion between the anterior chamber 16f of a casing for housing the anterior part of the rotating shaft 18 and the posterior chamber 16b of the casing for housing the posterior part of the rotating shaft 18 is sealed by a mechanical seal 28. The inside of the posterior chamber 16b is filled with a lubricant fluid to lubricate the bearings 26a, 26b of the rotating shaft 18 inside the posterior chamber16b, and a thrust bush 50 by the lubricant fluid. A blade 48 formed in a holding portion 38 is rotated to give a centrifugal force to the lubricant fluid, while the centrifugal force circulates the lubricant fluid between the posterior chamber 16b and a lubricant fluid tank 58, and filters the lubricant fluid by a filter 62 inside the lubricant fluid tank 58.
