A screw spindle machine having a tubular casing () that is made of cast metal and is lined with a wear resistant layer (), with the wear resistant layer () being encapsulated in a steel shell () that matches the outer peripheral shape of the layer ().

Screw spindle machine and method of manufacturing the same

A pump includes a cutting impeller () and a pre-chopper () driven by a shaft portion () that projects axially from the cutting impeller (), with the pre-chopper () being surrounded by an intake port () of the pump, the intake port having, at least on a part of its length, in the vicinity of the pre-chopper, a non-circular internal cross-section.

Pump with cutting impeller and pre-cutter

Method for manufacturing a machine housing having a fluid chamber () with a hardening layer () on an internal wall surface, in which the hardening layer () is made of a material, that, per-se, is not electrically conductive but has been made conductive by additives, and in that the surface of the hardening layer () is machined by electro-discharge machining.

Method for manufacturing a machine housing having a surface-hardened fluid chamber

A pump having an axial impeller () with helical blades () for sucking liquid through an intake opening () formed at a bottom side of the axial impeller (), in which the blades () are provided, at the bottom side of the axial impeller (), with a first cutting edge () which, when the axial impeller () rotates, are in cutting relation with at least one second cutting edge () formed at the intake opening ().

Pump with cutting impeller

Pump having a cutting impeller (), counter knives () associated therewith, and a pre-chopper () which is driven by a shaft portion () that projects axially from the cutting impeller (), characterised in that the counter knives () carry a cutting edge () that extends in longitudinal direction of the shaft portion ().

Pump with cutting impeller and pre-chopper

A rotary pump includes a pump chamber disposed above a liquid basin, and a radial impeller with a vertical axis disposed in the pump chamber. An intake connecting piece is disposed coaxially with the impeller and is positioned in the liquid basin. Either an inner part of the radial impeller or an axial impeller in the intake connecting piece, is provided for aspirating liquid in an interior region of the pump chamber. Venting channels lead from the interior region of the pump chamber to an outside and extend along a side wall of the intake connecting piece up to about a plane of the intake opening of the intake connecting piece. At least one venting channel has a lateral opening in the side wall of the intake connecting piece which opens essentially in a radial direction to the pump chamber.

Rotary pump with vented pump chamber

Centrifugal pump with a pump chamber (,) housing a radial impeller (,) and aspiration port arranged coaxially with the radial impeller, and at least one ventilating conduit (,) that leads from the inner radial area of the pump chamber to the outside, wherein the outer circumferential edge of the pump chamber (,) is fitted with interference contours (,) that are essentially directed tangentially to swirl the liquid flow.
