Inlet Sieve for Self-Priming Floating Pumps

In combination with a self-priming floating pump having a pump body and an inlet opening at an underside thereof that communicates with an impeller chamber of the pump to draw liquid into and through the impeller chamber under operation of the pump when floating in a body of said liquid, an inlet sieve comprising:

• a bottom wall;
• and
• a perforated outer wall upstanding from a topside the bottom wall and extending about an axis that passes through the bottom wall;
• wherein the inlet sieve is connectable to the pump in a position placing a bottom wall beneath the inlet of the pump at a distance therebelow with the inlet of the pump aligned with the axis, whereupon openings in said perforated outer wall enable liquid to flow into a space bound between the bottom wall of the inlet sieve and the underside of the self-priming floating pump for uptake of said liquid into the inlet opening of the self-priming floating pump;
• and
• wherein the bottom wall of the inlet sieve comprises an outer area spanning inwardly from the perforated outer wall toward the axis, and a protuberance that bulges upwardly from the outer area to an apex of the protuberance that is situated at the axis, whereby the liquid flowing into the space between the bottom wall and the underside of the self-priming floating pump is guided upwardly into the inlet opening of the self-priming floating pump by the protuberance of the bottom wall of the inlet sieve.
