Submarine seawater reverse osmosis desalination system

The centrifugal pumps find a wide application in the area of technology because of their hydraulical qualities, their capabilities to adapt oneself to variable operating conditions, and their ability to discharge different kinds of fluids. Today the designers of desalination and power plants pumps attempt to develop low cost and high efficiency pumps with a high reliability for the plants. This paper indicates the requirements to successful application of centrifugal pumps for desalination and power plants, and their realization, to optimise the reliability, the energy usage, the maintenance costs and to avoid an unsatisfactory hydraulic performance, high energy costs, high maintenance costs and poor reliability.
