Title: The Innovative Mind of Rudolf Fehlau

Introduction

Rudolf Fehlau, an ingenious inventor based in Downey, CA, has made significant contributions to the field of engineering through his innovative patents. With a total of two patents to his name, Fehlau's work primarily revolves around enhancing the efficiency and functionality of industrial pumps, aimed at addressing specific challenges in fluid mechanics.

Latest Patents

One of Rudolf Fehlau's notable inventions is the multi-stage centrifugal pump that incorporates a sealed thrust bearing. This advanced pump design features a linear series of impellers mounted on a common impeller shaft. The axial thrusts on the shaft, generated by the impellers, are effectively balanced by a sealed high-pressure thrust bearing assembly attached to the pump casing. This invention is particularly relevant for pumping abrasive fluids, as it prevents wear and erosion of pump components by ensuring that lubricating oil, supplied at a higher pressure than the abrasive fluid, migrates across the mechanical seal instead of the abrasive fluid itself.

His second patent involves a closure fastening means for a pump housing that includes a generally cylindrical bore. This design features a closure member connected to the housing via a closure ring and multiple shear studs. Each shear stud is received in threaded openings to enhance the structural integrity of the pump. The incorporation of compression bolts is designed to act on the closure member, ensuring that the assembly remains secure and robust under operational conditions.
