Abstract
A pump device (2), to be mounted coaxially in a pipe (3), includes an axial or mixed flow pump with a guide tube (7) arranged around a propeller portion of the pump device (2). In a mounting position, a gap (11) is formed between an upper end (16) of the guide tube (7) at an outlet portion (8) of the pump device (2) and the column pipe (3). The guide tube (7) has an elastic portion (12) connected to an outlet end of the guide tube (7). The elastic portion (12) is bendable in a radial direction towards the column pipe (3) in order to at least partially, in particular completely, close the gap (11) during operation of the pump device (2). Further, a pump system (1) includes the pump device (2).
