Abstract
A system including a seal cartridge is provided. The seal cartridge includes a housing defining a passageway that receives a driveshaft. A dry gas seal is circumferentially disposed about the passageway within the housing at a first axial location along the housing. A magnetic liquid seal is circumferentially disposed about the passageway within the housing at a second axial location along the housing. A fluid leakage cavity is formed between the dry gas seal at the first axial location and the magnetic liquid seal at the second axial location. An extraction port is disposed in the housing and enables recovery of a leaked fluid from the fluid leakage cavity.
