More Information
Summary:A hydraulic actuator for a cryogenic pump is provided. The hydraulic actuator includes a piston. The hydraulic actuator also includes a base housing. The hydraulic actuator further includes a push rod assembly. The push rod assembly includes a tube guide. The push rod assembly also includes a push rod. The push rod is adapted to reciprocate within the tube guide. The hydraulic actuator also includes a sealing assembly having a hollow cylindrical configuration. The sealing assembly includes a first static seal portion. The first static seal portion being connected to the base housing. The sealing assembly also includes a second static seal portion. The second static seal portion is connected to the push rod. The sealing assembly further includes an expandable annular bellow extending between the first and second static seal portions. The sealing assembly is adapted to prevent flow of a first fluid in a first direction.
