The water desalting installation comprises at least an auxiliary pump (1) and another high pressure pump (2) in parallel with an internal circulation pump (3), and at least one pair of feed chamber (5 and 5') which are pressurized alternatively, each of them forming a closed circuit, preferably toroidal, so that the water circulates always in the same direction and continuously, taking advantage of its kinetic energy in the valve actuation; it may have separation means to separate the water masses of different salinity, said separation means being comprised of pistons (7 and 7') having a spherical shape and of which the apparent density is similar to that of the water, said pistons being retained briefly during the cycle change by baskets (6 and 6') or equivalent devices, while the water circulates to the expense of its kinetic energy, the cycle changes being controlled by approximation (29 and 29') and housing (28 and 28') sensors, or by flowmeters (31, 31' and 32) or by salinity measures when such separation means are not available.
