A rotary machine such as a pump has a vertical driveshaft suspended from the upper end and provided at the lower end with an impeller surrounded by a casing in which provision is made for a suction chamber fitted with stationary radial vanes integral with the casing. The driveshaft is rotatably mounted in a hydrostatic bearing placed beneath the impeller, a removable sleeve being mounted coaxially with the shaft between the suction chamber and the impeller.
