A wastewater pump for conveying solids-laden wastewater includes a spiral housing with an inlet opening, an impeller with at least one vane having a leading edge running from the impeller hub in a backwardly curved manner, and at least one finger for wiping off contaminants from the leading edge. The at least one finger is arranged on the inlet inner wall and extends in the direction of the impeller rotational axis. At least one groove is present in a suction-side inner wall of the housing to receive and convey material that is removed by the at least one finger from the leading edge to. The leading edge of the impeller and the surface of the at least one finger which faces toward the leading edge are at an angle of 5° to 75° with respect to the rotational axis.

A pump assembly for delivering a medium via a flow chamber () defined by a hydraulic housing and a housing cover, includes a pump shaft rotatably drivable about an axis of rotation, an impeller fixed to one end of the pump shaft inside the flow chamber, a bearing carrier. The pump assembly further includes a lubrication and cooling system with oil recirculation in the bearing carrier.

Pump assembly comprising a lubrication—and cooling system

A centrifugal pump for delivering a medium comprising solid admixtures includes a blade-free space arranged in front of an impeller. The centrifugal pump has a suction-side arrangement that permits variable sizing of the blade-free space. The suction-side arrangement permits the efficiency of the centrifugal pump to be increased while avoiding blockages.

Vortex pump

A vortex pump with an impeller is provided. The impeller includes blades for delivering solids-containing media which are arranged in bundles. The spacing the blades in the bundles is smaller than the spacing of the bundles from each other.

A pump arrangement, in particular a magnetic clutch pump arrangement, includes a pump housing containing an impeller shaft, a containment shell which seals an enclosed chamber within the inner chamber of the pump housing, an impeller mounted on one end of the impeller shaft, an inner rotor mounted on the other end of the impeller shaft, an outer rotor which is mounted on the drive shaft and co-operates with the inner rotor, and an auxiliary impeller mounted in the chamber adjacent to a domed base of the containment can. The auxiliary impeller is secured to the inner rotor and includes vanes and impeller channels for circulation of media.

Pump arrangement

An immersion pump is provided, the pump having an integral housing with an inlet opening on an intake side, an outlet opening on a delivery side, a passage for electrical lines, an electronic unit for processing power and optionally information signals, an electric motor, a pressure chamber and a pump unit. The electronic unit, the electric motor, the pressure chamber and the pump unit may be pre-assembled to an insert, with the pre-assembled insert being supported on one end of the housing. An axial clamping and/or fastening system, in particular a tapered locking arrangement, is provided on the opposite end of the housing.

Immersion pump and method for assembling an immersion pump

A rotor mounting on one end of a shaft, particularly a shaft end of a centrifugal pump unit, in which an adjusting surface and at least one contact surface are constructed on the shaft end, and in which a rotor hub is provided at least on the end facing the shaft with a central bore having an internal thread. The rotor hub is attached to the shaft end by a screw connection. The shaft has a central bore () having an internal thread () at least on the end facing the rotor hub (); a threaded pin () constructed as a separate component is disposed in both central bores () in a connecting, torque-transmitting and force-transmitting manner, and the rotor is aligned on the shaft solely by the adjusting surfaces () and contact surfaces ().

Rotor mounting

A pitot tube pump having a hydraulic chamber, a fluid supply line, a fluid discharge line, and a drive, in which the supply line, the discharge line and the drive are all arranged on the same side of the hydraulic chamber. A pitot tube preferably is mounted in the hydraulic chamber on a shoulder of a fixed shaft in communication with the discharge line. The drive is preferably an electric motor with a stator which is connected in a rotationally secure manner to the fixed shaft, and a rotor which forms a part of the hydraulic chamber or which is connected in a rotationally secure manner to the hydraulic chamber.

Pitot tube pump

A feed pump with a variable-speed drive for adjustably metering a feed quantity, which is designed as a single-stage centrifugal pump with a radial wheel arranged to rotate, without a sealing gap, in an impeller chamber of a pump casing, to convey a fluid between a pump inlet and outlet. The radial wheel is connected to a variable speed drive motor having a five-digit rotational speed range, receives the flow centrally, is provided with feed ducts, and has an outside diameter of up to 50 mm, while the centrifugal pump is designed for partial-load operation, the feed quantities of which range from 0 to 3600 ml/min with lifts of 20 to 300 meters. The inside diameter of the impeller chamber is at most 4% larger than the outside diameter of the radial wheel. A seal is arranged between the impeller chamber and the radial wheel or its shaft, and the circumference of the impeller chamber is provided with one or more outlet ducts arranged at an acute angle or tangentially to the outside diameter of the radial-wheel.

Feed pump

A valve for switching over liquid paths, particularly for pressure exchanger installations with tubular pressure exchanger chambers () through which an alternating flow occurs, in which a rotatable control element () having a plurality of flow paths is mounted in a housing (), which in turn comprises a plurality of connection opening () connected to a first pipe system and to an end of at least one pressure exchanger. Another end of the pressure exchanger is connected to a second pipe system through a valve. A motorized drive shaft () rotates the control element so as to alternately connect the control element flow paths to openings inside housing (). Oncoming flow to the control element may come from an axial direction or from a radial direction, and outgoing flow from the control element occurs in the axial direction.

Valve unit for pressure exchanger installations

A valve for switching fluid paths, particularly for pressure exchanger installations with tubular chambers through which fluid flows in an alternating manner, including a rotatable closing element () provided with a motorized drive shaft () and arranged inside a housing () having a plurality of connections () for connecting lines leading to a pipe system and to a respective end of at least one pressure exchanger. Another end of each pressure exchanger is connected through a valve arrangement to a second pipe system. A splitter () provided with a plurality of overflow paths () is arranged inside the housing (); mouths of the overflow paths are located on two axial end faces () and on the circumference of the splitter (), and a rotatable, disk-shaped control element () is arranged in a sealing manner at each end face of the splitter ().

Flow-reversing valve

An impeller of a centrifugal pump for transporting dirty liquids has transport elements, for example back-vanes or grooves disposed on the pressure side of a cover disk. The transport elements are arranged asymmetrically and are limited to one arc sector of the cover disk to create a transverse stream that rotates with the impeller. Solids which have penetrated into the space to the side of the wheel are carried out by this stream in the direction of the transport elements.
