Christoph Boehnisch has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Eccentric screw-type pump with spare stator
    Patent number: 7104770
    Abstract: The present invention relates to the arrangement of a stator and a spare stator. In order to avoid a permanent correction in the length of the driving shaft, the spare stator is connected to the instantaneously operated stator or is configured in a single piece. Upon occurrence of a defined amount of wear, this stator combination is merely reversed through 180° relative to the longitudinal axis or an intermediate tube is inserted so that the spare stator arrives in the rotor region.
    Type: Grant

  • Eccentric screw-type pump with spare unit
    Publication number: 20040057846
    Abstract: The present invention relates to an eccentric screw-type pump. Due to their contact with the product to be pumped, the rotor and the stator of an eccentric screw-type are subject to a permanent wearing process. As the exchange of corresponding components subject to wear involves down times or requires special tools, the inventive eccentric screw-type pump is provided with a spare unit including, in particular, the stator, the rotor, the shaft, the driving shaft and the seal.
