Abstract
A pump having tandem seals includes a pump shaft, a pump housing, an inboard seal, an outboard seal, and a gland assembly. The pump housing defines a primary chamber between an interior surface of the pump housing and an outer surface of the pump shaft when the pump shaft is disposed within the pump housing. The inboard seal, the outboard seal, and the gland assembly are configured to be disposed within the primary chamber of the pump housing. The gland assembly is disposed between the inboard seal and the outboard seal, and the inboard seal, the gland assembly, and the outboard seal are configured to form a plurality of chambers within the pump housing.
