Abstract
To enable centrifugal filtration of fluids which contain abrasive contaminant particles the rotor bearings (3) must be isolated from the fluid which passes into and through the rotor chamber (21). This is achieved by a design in which the spindle (4) is connected to the rotor so as to rotate in unison with the rotor (5, 6, 7) relative to the base (1). The bearings (3) for the spindle (4) are provided in a bearing housing (2) which is fixedly mounted to the base (1) and a sealing arrangement, preferably a spring-loaded axial seal (14, 15), is provided between the spindle (4) and the base (1) at a location below the bearings (3) in the bearing housing (2).
