Abstract
A mechanical seal assembly is disclosed in which the seal faces of the primary seal members remain essentially perpendicular to the shaft of the equipment regardless of any misalignment. A sleeve is mounted on the shaft, providing a support structure to align all primary seal member faces regardless of loading. The primary seals are biased toward the support structure, by the combination of net hydraulic pressure at the mated seal faces plus steady bias from a biasing source. A piston area is defined on the rear of each primary seal member. Each piston area is equal to a major portion of the associated primary seal face contact area. Another embodiment further includes a gland mounted to the equipment concentrically to the equipment shaft and an axially floating annular flow ring located within the gland. The ring supplies a fluid flow channel associated with the shaft vanes.
