The paper describes the construction and operation of a multistage centrigugal pumps driven by a water-filled electric motor. The pumpe set can be installed submerged in water at great depths, and is capable of satisfactory operation for several years, without maintenance or service. The present paper describes the advantages of this type of pumpe for offshore and onshore technology appications, with the aid of a few examples: a) for pumping of hydrocarbons out of underground storage caverns, b) for trimming and ballast duties on drilling and production platforms, c) for fire-fighting duties, because of their reliable and maintenance-free operation, d) for deep sea applications, where the pumpe set is capable of operating submerged at depths of several thousand metres. The submersible motors described represent the culmination of many years of research and development; they are available in outputs up to 2000 kW and for high tension supply voltages from 3000 to 10000 volts.
