Abstract
The present cartridge seal assemblies pertain to rotary lip-type seals. In certain embodiments, a sealing member is constructed of a relatively hard material that increases the lifespan of the sealing member. The sealing member is energized with a canted-coil spring, which in some embodiments includes an adjustable spring force. The present embodiments enable control of sealing force to achieve an appropriate sealing force between the sealing member and the shaft based on factors such as temperature, pressure, rotary speed, properties of fluid media, etc. to achieve longer seal life.
