Abstract The seal parts for pump shaft are important parts of centrifugal pump.In this study several non-leakage rotary seals for centrifugal pumps(including stratiform shearing type packing seal,magnetic fluid seal,dry-gas seal,power seal,and stop seal etc.),the structure,the characteristics and applicable situations are discussed.Successful cases from home and abroad are enumerated.Moreover,a kind of pump of special structure that changes the inhalation to the side is introduced which makes the pumps having no leakage to some extent.By applying these radial sealing measures safe sealing can be realized.
