  • Patent number: 11441560
    Abstract: A pump housing (4) for an eccentric screw pump, comprising a housing casing (5) extending along a housing longitudinal axis (L), a first end-face opening (6), to which a shaft seal (7) for a connection shaft (8) can be connected, and a second end-face opening (10), to which a stator (I) can be connected, and comprising a tubular inlet nozzle (11), oriented transversely to the housing longitudinal axis (L), for feeding a medium that is to be conveyed, which inlet nozzle is connected to the housing casing (5) tangentially, offset in relation to the housing longitudinal axis (L). The geometry of the inlet nozzle (11) is designed in such a way that, as the medium flows into the housing interior through the inlet nozzle (II), a flow (S) is generated which has a radial direction component (RI) directed away outwardly from the housing longitudinal axis (L) and/or an axial direction component (R2) directed towards the first end-face opening (6).

  • Patent number: 10717612
    Abstract: A system for conveying pasty material through a conduit has an eccentric screw pump having a stator, a rotor that rotates in the stator, a housing with an intake port, and an output port connected to the conduit. A drive rotates the rotor and thereby draws the pasty material in through the intake port and expels the drawn-in material as a compressed-material strand into the conduit. A valve supplies gas pulses to the conduit at time intervals for separating the compressed-material strand into material plugs of limited length traveling through the conduit.
