Mechanical seal device with microsystem, pump device using the same and method of operating the same
Patent number: 11867292Abstract: The invention concerns a mechanical seal device (1) with a mechanical seal (10) which comprises a dry-running protection device (20), the dry-running protection device (20) having at least one microsystem (21) which outputs a digital measured value (W), the microsystem (2) being arranged adjacent to the mechanical seal (10) and/or on and/or in the mechanical seal (10). The measured value (W) makes it possible to protect the mechanical seal (10) from overloads. Furthermore, the invention concerns a pump device (100) with such a mechanical seal device (1), the mechanical seal (10) being arranged in a shaft passage (102) and sitting on a pump shaft (103). Furthermore, the invention concerns a method of operating this pump device (100) in which the speed of a drive motor (105) of the pump shaft (103) is adapted on the basis of the digital measured value (W) of the microsystem (21).Type: GrantFiled: October 7, 2019Date of Patent: January 9, 2024Assignee: Herborner Pumpentechnik GmbH & Co KGInventors: Sascha Korupp, Florian Schneider, Lars Runte, Nils Reeh -

Patent number: 9651074Abstract: A connection system (1) for detachably connecting a component element to a coated component part (3), includes a coupling element (2) that has a head (6) with a non-round outer cross-section and has a shank (5). The head (6) can be received by a frictional connection in a rotationally fixed manner in a head region (11) of a connection opening (4) of the component part (3). The shank (5) can be received in a friction-locked and/or firmly-bonded manner in a sealing region (12) of the connection opening (4). The head (6) has an internal geometry for connecting the component element.Type: GrantFiled: September 9, 2013Date of Patent: May 16, 2017Assignee: Herborner PumpenfabrikInventors: Sascha Korupp, Lars Runte, Felix Hees

Patent number: 9447793Abstract: The invention relates to a centrifugal pump (1) that has a suction-side inlet (3) and at least one pressure-side outlet (4), wherein a rotatably mounted impeller (5) for pumping a pump medium from the inlet (3) to the outlet (4) and an impeller seat (10) are arranged in the pump housing (2). In order to achieve a high degree of sealing and a long service life, the impeller seat (10) is formed in a ring-shaped impeller protector (8) which is made from a corrosion-resistant material and is received in the pump housing (2), wherein an insertion region (7) of the impeller (5) is radially surrounded by the impeller protector (8). This impeller protector (8) protects the coating against damage to the impeller (5) in the impeller seat (10).Type: GrantFiled: September 9, 2013Date of Patent: September 20, 2016Assignee: Herborner Pumpenfabrik J.H. Hoffmann GmbH & Co. KGInventors: Sascha Korupp, Lars Runte, Felix Hees
