Abstract
The pump has a pump body having a pump body portion with a vent hole to allow air entrapped in the pump body to bleed out to atmosphere and allow liquid to fill the pump body in order to get the pump running, and also includes a tab receiving portion having a rim defining an opening; and a pump/strainer assembly that includes a base with slots/openings formed therein to receive and strain liquid to be pumped, and includes a strainer retaining tab with a raised rim to be received in the opening of the tab receiving portion and circumferentially engaged by the rim of the opening to hold together the pump/strainer assembly and the pump body. The at least one tab receiving portion and the strainer retaining tab are dimensioned to conceal the vent hole and substantially prevent the liquid from bleeding through the vent hole and squirting outside of the pump body when the pump is running.
