Abstract

Eine Radialpumpe für Fluide weist einen zentralen Wassereinlass auf, der zu einem rotierenden Impeller führt, der von einer ringartigen und radial außerhalb verlaufenden Pumpenkammer umgeben ist, aus der ein Wasserauslass herausführt. In der Pumpenkammer ist eine Zwischenwand angeordnet, die ganz umlaufend ausgebildet ist und die Pumpenkammer in einen radial innenliegenden ringförmigen Innenbereich und einen radial außenliegenden ringförmigen Außenbereich unterteilt. Diese Bereiche gehen an einem vom Impeller entfernten Ende der Pumpenkammer ineinander über durch Ausnehmungen der Zwischenwand, wobei der Wasserauslass vom Außenbereich abgeht.

Figure imgaf001
A fluid radial pump has a central water inlet leading to a rotating impeller surrounded by an annular and radially outwardly extending pumping chamber from which a water outlet passes. In the pump chamber, an intermediate wall is arranged, which is formed completely encircling and dividing the pump chamber into a radially inner annular inner region and a radially outer annular outer region. These areas merge into one another at an end of the pump chamber remote from the impeller through recesses of the intermediate wall, wherein the water outlet leaves from the outside area.
