Abstract: An assembly for being dragged by a vessel, wherein the assembly includes a filtering system and a fluidum guiding system, wherein the filtering system is suitable for filtering large volumes of fluidum, and wherein the fluidum guiding system defines a channel configured such that at least in a channel portion the current velocity of the fluidum guided through that channel portion is reduced downstream, and wherein the fluidum guiding system and the filtering system are mutually arranged such that current velocity of fluidum filtered in the filtering system is reduced for decreasing drag.

Abstract: An impeller for a centrifugal pump comprises a rotor; a shaft shield connected to the rotor and having an axial supply; a suction shield connected to the rotor and axially set apart from the shaft shield; and a plurality of blades between the shaft shield and suction shield and connected to the rotor. Each blade comprises a leading edge and a trailing edge connecting between the shaft shield and the suction shield and a suction side and a pressure side, wherein each blade cross-section is thicker near the leading edge on the suction and pressure sides, and tapers to a thinner cross-section near the trailing edge. Each blade connects to the suction shield at the leading edge with an extensive fillet providing curvature toward the suction shield along the leading edge.

Abstract: A blade for an impeller comprises a blade with a front portion with a leading edge and a trailing portion with a trailing edge joined by spaced apart pressure and suction sides to form an exterior blade surface. The blade pressure side is formed from an outer envelope of a first blade profile aligned in a first position; and at least a part of the front portion of the blade suction side is formed by rotating the first blade profile around the leading edge to match an angle of the incoming flow at a lower flowrate condition of the impeller.
