Abstract: A shaft sealing assembly for static and dynamic sealing includes a stator member attached to a housing and a rotor member attached to a shaft rotatable about an axis. The rotor member includes first and second pocket sections extending from upper and lower radial flanges extending in a cantilevered fashion from a tubular member. At least one static sealing member is attached to and encapsulates each pocket section. Each static sealing member presents a core portion and a pair of radial lips extending from the core portion. The stator member presents an annular wall extending to inner walls inclined conically to a central radial rim or flange separating two pocket portions and the static sealing members presenting a contact and frictionally engaging with the central radial rim as the rotor member is at a stand-still or static position.

Abstract: A seal assembly includes a stator attached to a housing and a rotor attached to a shaft. A static sealing member is attached to the stator presenting a contact with the rotor at stand-still. An electromagnetic is attached to the stator at a distance from an end of the static sealing member. The static sealing member is activated and moved away from the rotor by the magnetic force exerted by the electromagnet as the shaft rotates. The electromagnet is controlled by a control system for controlling the equipment in which the bearing isolator is used. To deactivate the static sealing member during shaft rotation, the bearing isolator may have its own control system with a sensor to indicate if the shaft is rotating. As the shaft rotates, contaminants are expelled through gaps between the stator and the rotor.

Abstract: A wear sleeve assembly for a seal on a shaft includes a sleeve having inner and outer circumferential surfaces, the outer surface being engageable by a seal inner surface at a contact location to prevent fluid flow between the seal inner surface and the sleeve outer surface. The sleeve inner surface defines a bore sized to receive a portion of the shaft with clearance. A coupler is configured to connect the sleeve with the shaft and provides a clearance space between the sleeve inner surface and a shaft outer surface at about the seal contact location. Thereby, the sleeve is adjustably positionable relative to the shaft so that the sleeve remains generally centered within the seal as the sleeve and shaft rotate about the axis. The coupler preferably includes an annular body with first and second axially-spaced, relatively displaceable sections for displacing the sleeve relative to the shaft.
