    Abstract: A rotor positioning system for pressure exchangers using a central stationary axle. Hydrostatic bearing features on each end are separated by a hydradynaroic bearing surface. Each end of the axle contain a radial manifold directly connected to each high, pressure fluid stream from where the fluid flows through the annular- clearance space between the axle and the rotor bore towards a circumferential groove at each bore end. This groove drains through the end clearance between rotor and each end cover into the low pressure stream. Any rotor movement away from a central axiaf position builds up unequal, pressure in each groove and seeks to correct such movement Excessive radial movement of the rotor is resisted by the hydrodynamic action and in particular during start-up and low RPM by the hydrostatic bearing features.
