A filtering pump assembly for pumping and filtering a fluid includes a pump subassembly and a filter subassembly. The pump subassembly has an inlet portion with a first cross-sectional shape. The preferred cross-sectional shape of the inlet portion is circular. The filter subassembly includes a foraminous cage member, having an opening formed therein of a shape corresponding to the first cross-sectional shape of the inlet portion and being configured to fit engagably thereon. The filter subassembly also includes a filter element formed of a porous material for placement in covering relation to the cage member. The preferred filter element is either bag-shaped or formed as a cylindrical sleeve. Preferably, the filter assembly includes a retainer for retaining the filter element in covering relation to the cage member. The retainer may be an annular spring clip having two ends which overlap one another, and having a finger grip formed at each end thereof. |
