Abstract (en)

A pump assembly (100) includes a pump housing (110) adapted to house a drive motor (112) therein. The pump housing (110) defines an inlet opening (114), an outlet opening (116) and a drainage opening (118) therein. A drainage plug (120) is adapted to be engaged with the drainage opening (118). The pump assembly (100) is characterized in that the drainage plug (120) includes a first plug element (120A) having a first cross-sectional area (A1) and a second plug element (120B) having a second cross-sectional area (A2). The second plug element (120B) is coupled to the first plug element (120A) through a coupling rod (120C). A cross-sectional area (A3) of the coupling rod (120C) is smaller than the first cross-sectional area (A1) and the second cross-sectional area (A2).
