ABSTRACT:
An integrated barrier fluid sealing apparatus includes an annular pressure intensifier surrounding a shaft of an operational device and defining a chamber extending around and along the shaft and containing a barrier fluid. The integrated apparatus also includes an annular sealing arrangement mounted to the pressure intensifier and surrounding the shaft so as to provide a seal around the shaft such that the pressure intensifier and sealing arrangement cooperate to prevent leakage of process fluid along the shaft to an external environment. A visual barrier fluid volume indicator mechanism also is provided which cooperates with operation of the pressure intensifier to visually indicate the volume of barrier fluid in the chamber of the pressure intensifier.
