This article describes the use of non-balanced mechanical seal to solve the problem of light hydrocarbon shaft seal. The influence of the vapor phase and the liquid phase on the fluid membrane is analyzed in detail. An example of the unbalanced seal applied to the light hydrocarbon pump is given. Experimental studies are carried out to obtain satisfactory results.
