摘要： An eccentric screw pump for delivering solid-laden liquids includes a rotor and a stator within which the rotor is rotatably arranged. The rotor and stator are arranged and designed with respect to one another in such a way that at least one chamber is formed, which serves to transport the liquid. The eccentric screw pump has a drive motor for rotating the rotor, a control device for controlling the drive motor at least in a working state, in which the rotor is rotated, and an idle state, in which the rotor does not rotate, and an engagement unit, which is designed to set an engagement between the rotor and stator to an idle engagement in the idle state and to a working engagement in the working state. The idle engagement is less than the working engagement. A method for operating the eccentric screw pump is also disclosed.

摘要： A distributor device for solids-containing liquids includes a distribution chamber with an inlet opening which leads to a chamber interior space of the distribution chamber, wherein the distribution chamber has a first end wall with several connection ports and a first side wall arranged laterally to the end wall. The distributor device also includes a connecting part connecting the rotor and the blade drive shaft, which connecting part is detachably connected to the rotor and/or to the blade drive shaft, wherein a movement of the rotor is guided by the connecting part relative to the first perforated blade disk. The distribution chamber has at least one closable opening which is located in the first side wall, wherein the opening is designed at least so large that the rotor is removable from the distribution chamber through the opening.

摘要： A seal assembly for sealing a pump shaft in a rotary piston pump configured for conveying pump-conveyed fluid comprises a sealing-fluid pump device having a pump inlet and a pump outlet. A blocking chamber is connected to the pump outlet and is disposed so as to neighbor the pump chamber of the rotary piston pump and is sealed in relation to the pump chamber by means of a first shaft seal that encloses the pump shaft. The blocking chamber by way of the pump outlet is impinged with a fluid pressure resulting from the fluid pressure differential that is generated by the sealing-fluid pump device, whereby said fluid pressure interacts with the first seal assembly to seal the pump chamber in relation to the egress of pump-conveyed fluid from the pump chamber along the pump shaft.

摘要： A comminuting device for solids-conducting liquids includes a housing with an inlet opening, an outlet opening, and a housing interior extending from the inlet opening to the outlet opening, a first comminuting shaft extending through the housing interior and arranged to rotate about a first comminuting axis. A second comminuting shaft extends through the housing interior and is arranged to rotate about a second comminuting axis. A screening device has a screening wall comprising a plurality of slots arranged in the housing interior adjacent to the first comminuting shaft. A clearing device has a plurality of clearing elements which can be moved relative to the screening wall along a movement path and which extend through the plurality of slots starting from a clearing shaft arranged on one side of the filter wall to at least one portion of the movement path.
