Vertical frame bars (20) extend to a lower coupling piece (17) to the pump. A spiral (14) is formed by bent frame bar and is fastened at one end (21) to a frame bar (20) and fixed (20) to the other frame bar, extending at least to the latter bar and having its other end (23) left free at the height of the frame bars. Preferably the frame bars extend over a distance above the fixing point and the cross piece is in the upper third of the spiral.
