ABSTRACT:
An aquarium filtration system is formed as a filter assembly for mounting on the wall of an aquarium tank, and includes a pair of filter chambers, each having a filter element, mounted side by side along the aquarium wall. An inlet conduit is located in a transverse medial plane of the assembly. A water pump including a rotating impeller is located between the two filter chambers, and pumps water from the aquarium tank, via the inlet conduit, into a corridor which communicates with the two filter chambers. The impeller is constructed with relatively closely spaced radially extending blades, each of which is formed of a circular disk. A base edge, or chord, of each blade is inclined upon a frustoconical surface of a central hub of the impeller. A discharge end of the inlet conduit directs water upon the impeller blades, the latter urging the water outward along a horizontal plane into the corridor. A lower end of the inlet conduit terminates in a housing structured as a cage with plural ports for unrestricted delivery of water from the impeller into the corridor. A stream diverter is located adjacent the impeller for directing water from the impeller in equal quantities to both of the filter chambers. In smaller single filter chamber systems a single fin diverter can be used. This construction reduces noise and turbulence in the filtration system.
