Title: Richard Hosanna: Innovator in Barrier Seal Systems

Introduction

Richard Hosanna is a notable inventor based in Morton Grove, IL (US). He has made significant contributions to the field of engineering, particularly in the development of barrier seal systems. With a total of 2 patents to his name, his work has had a considerable impact on sealing technologies.

Latest Patents

Richard's latest patents focus on barrier seal systems designed to seal the annular space between a housing and a rotating shaft. These systems feature inboard and outboard mechanical end face seals. The inboard seal faces are equipped with spiral grooves that pump a buffer fluid from a buffer chamber toward the high-pressure side of the inboard seal. The primary ring of the inboard seal may be double balanced, which enhances its performance in high-pressure applications. Additionally, the buffer fluid can be pressurized, and a pumping ring may be included in the outboard seal to facilitate the circulation of buffer fluid. High-pressure applications also necessitate the use of two hard seal rings and optimal dam and face widths. A reservoir connected by a gravity feed line supplies buffer fluid to the seal system, and a containment device may be attached to the high-pressure side to prevent contamination of the seal faces or secondary seals.
