Abstract
A seal cartridge for providing a fluid seal between a rotating shaft and a housing such as found in a centrifugal pump. The seal cartridge includes rotating and non-rotating seal portions which prior to installation are maintained in alignment and carried by a tubular or sleeve-like support member so that the cartridge forms a unitary assembly. The non-rotating seal portion includes a seal ring seat that is connected to the support sleeve by a frangible element. During an installation process, after the seal ring seat reaches its installed position, the frangible element fractures and releases the non-rotating portion of seal from the support member thus enabling the rotating portion of the seal to rotate relative to the non-rotating portion. The support sleeve can be rigidly clamped to the shaft by a conventional pump impeller.
