Abstract (en)
A discharge head for a vertical pump is proposed comprising a base plate (11) for mounting the discharge head, a top plate (12), at least one support member (13) connecting the base plate (11) with the top plate (12), a discharge pipe (15) with an outlet (16) for delivering a fluid, said discharge pipe (15) extending through the base plate (11), and an inner tube (17) for receiving a shaft (4) that connects a drive unit (3) with an impeller (21) of the vertical pump, wherein the inner tube (17) extends in an axial direction (A) and coaxially within the discharge pipe (15) in the region of the base plate (11), passes through a wall of the discharge pipe (15) at an intersection (18), and further extends to the top plate (12), wherein the inner tube (17) comprises a bellows member (19) being located between the intersection (18) and the top plate (12). In addition, a vertical pump with such a discharge head (10) is proposed
