Abstract: An impeller includes a shell having a plurality of blades. The shell may also define a cavity. The impeller may further include a backplate that engages at least a portion of the shell. The backplate can include a post which can be coupled to the impeller through a fastener such as a threaded nut. The backplate can be thereafter clamped to the impeller shell. Seals can be provided in the impeller, such as in the backplate. The backplate and impeller shell can be piloted onto each other. In some forms splines can be used to secure the backplate to the impeller shell.

Abstract translation: 叶轮包括具有多个叶片的壳体。 外壳也可以定义一个空腔。 叶轮还可以包括接合壳体的至少一部分的背板。 背板可以包括可以通过诸如螺母的紧固件联接到叶轮的柱。 之后可以将背板夹紧到叶轮壳体上。 密封件可以在叶轮中提供，例如在背板中。 背板和叶轮外壳可以互相引导。 在某些形式中，可以使用花键将背板固定到叶轮壳体上。
