ABSTRACT:
A refrigeration compressor seal for inhibiting the loss of refrigerant between a compressor shaft and a compressor housing. The seal includes a face seal comprising a seal nose and a mating ring positioned in opposing relation to the seal nose. The mating ring includes tungsten carbide (e.g., solid tungsten carbide with 6% nickel binder). The seal nose comprises a maximum of about 0.5 weight percent lead (e.g., a low lead tin bronze allow, such as alloy C90300). A lip seal is operatively positioned between the compressor housing and the compressor shaft. The lip seal and the face seal collectively form a seal cavity for retaining fluid adjacent to the face seal. The seal assembly can further include a bypass channel for bypassing fluid around a top portion of the lip seal.
