Abstract: A pump assembly has at least one electronics receiving space (54; 54; 54″). The electronics receiving space (54; 54; 54″) includes at least one defined ventilation opening (40; 40; 40″). The ventilation opening (40; 40; 40″), at an outer side of the electronics receiving space (54; 54; 54″), runs out into an air duct (41; 41; 46; 46; 48, 48′) which is led along at least one condensation surface (60; 60; 60″).

Abstract: A sensor arrangement includes a sensor which is arranged in a housing constructed of two plastic injection molded parts (2, 3). The electrical leads are sealingly led through the housing (1) and are sealed by way of O-rings which on the one hand bear in a groove of the lead and on the other hand bear in a recess forming the housing feed-through.

Abstract: A pump assembly includes an electric drive motor with a terminal box (6) arranged on the electric motor (4). At least one metallic component (34) extends from the electric drive motor (4) into an inside of the terminal box (6). A capture device (38, 40), for capturing condensation water collecting on the metallic component (34), is arranged in a proximity of the metallic component (34) in the inside the terminal box (6).
