Floating rings are widely used in the sealing assemblies of the shafts of pumps and turbine pump units. However, information about the use and design of floating rings is not widely available in the literature and does not satisfy the practical interest in their use. The article touches on questions related to the operating mechanism of seal assemblies with floating rings and the structural realization of these assemblies, and considers questions related to their design. The potential of the computational method in the use of the traditional approach to the calculation of the flow through a seal and the input losses in a groove channel is analyzed and a technique of improving the computational method is proposed.
