Abstract:
Seal assemblies for sealing around a moveable shaft, such as rotary or reciprocating, or static, are described. The seal assemblies prevent the passage of lubricant or fluid from a relatively high pressure area on a first side of the seal to a relatively low pressure area on a second side of the seal. In some embodiments, these seals are energized by energizers, such as circular springs or canted springs, to keep the seal in contact with the moveable shaft. The seals have primary and secondary seals. The secondary seal provides initial moderate sealing against abrasive particles or contaminants to reduce the exposure and wear of the primary seal.
