Artur Hager

Title: Artur Hager: Innovator in High-Pressure Pump Seals

Introduction

Artur Hager is a notable inventor based in Munich, Germany. He has made significant contributions to the field of engineering, particularly in the design of seals for high-pressure pumps. His innovative approach has led to the development of a unique sealing mechanism that enhances the efficiency and reliability of gear pumps used for melted polymeric materials.

Latest Patents

Artur Hager holds a patent for a "Seal for high pressure pump or the like." This invention features a seal for the drive shaft of a gear pump, which includes a reduced pressure zone, a mechanical packing seal, and a liquid-filled chamber positioned in succession along the drive shaft. The liquid serves as a solvent for the polymeric material and is maintained under a pressure slightly above that in the reduced pressure zone. This design allows a small quantity of the liquid to move axially into the reduced pressure zone, effectively dissolving any polymeric material that may leak into it. The functionality of the seal can be monitored by tracking the volume of the liquid, as any polymeric material leaking through the packing seal will be dissolved, thus increasing the liquid volume.
