A review of literature on research studies of optimal cooling of magnetic coupling of chemical rotodynamic pump is performed. Today, this subject is particularly relevant. Issues of ecology, as well as fire and explosion safety at workplace are increasingly being raised. In order to solve this kind of problem in chemical and petrochemical industry, it is advisable to use hermetic pumps with magnetic clutch and hermetic electric motor. The main problems of using such pumps, identified as a result of the review, were problems of heat balance in cooled magnetic coupling and calculation of fluid flow in auxiliary paths. These problems are solvable, but highly energy-intensive, so the use of hermetic pumps is advisable in cases where the benefit exceeds risks and complexity of design.
