A method of manufacturing a metallic rotor of an eccentric screw pump, comprising clamping a workpiece extending along a central longitudinal axis in a workpiece clamping device and removing material from the workpiece by cutting with a cutting tool. The invention further comprises not producing the surface of the rotor in a three-axis whirling process, using the cutting tool to produce the outer surface geometry of the rotor, advancing the cutting tool along an axis of advance that is parallel to the longitudinal axis of the rotor, and rotating the cutting tool about an axis of tool rotation that is parallel to the longitudinal axis of the rotor.

A dual-shaft shredder for comminuting solids or solids in liquids comprises a housing defining an interior comminuting space, an inlet opening, an outlet opening, and a first and second cutting disc block each having a plurality of cutting discs disposed on a hub body such that an intermediate space is present between each two adjacent cutting discs. Some of the first cutting discs each engage in the intermediate space between two adjacent second cutting discs and some of the second cutting discs each engage in the intermediate space between two adjacent first cutting discs. A first shaft stub and a second shaft stub extend into an axial recess of the first and second cutting disc blocks for transmitting torques, and a first clamping device and a second clamping device clamp the shaft stubs against the cutting disc blocks.

The invention relates to a rotary lobe pump including a pump housing with a pump chamber, an inlet opening and an outlet opening. A first multi-lobed rotary piston is rotably mounted around a first axis in the pump chamber. A second multi-lobed rotary piston is rotably mounted around a second axis in the pump chamber and meshes with the first rotary piston. The first and second rotary pistons are rotated by a drive unit to create a fluid flow from the inlet opening to the outlet opening. The drive unit includes a first electric drive motor mechanically coupled with the first rotary piston and a second electric drive motor mechanically coupled with the second rotary piston.

The invention relates to a rotary lobe pump for conveying a fluid medium containing solids, comprising an inlet and an outlet for the medium being conveyed, and further comprising a pump casing and two rotary lobes arranged in said pump casing and having intermeshing rotary lobe vanes. According to the invention, the pump casing has two opposite casing half-shells which seal the pump casing fluid-tightly. The casing half-shells are double-walled.

A screw conveyor for introducing organic matter into a biogas digester that is under internal gas pressure. A biogas plant may be provided with such a screw conveyor, and methods for feeding organic solids to such a biogas plant may be performed. A plug section of the screw conveyor has an expansion region in which the passage cross-section between the conveying screw and the screw pipe widens in the conveying direction and a constriction region located downstream from the expansion region, in which the passage cross-section between the conveying screw and the screw pipe is reduced in the conveying direction.
