Abstract
A limit ring for use in a pump arrangement includes a cylindrical body positioned about a central longitudinal axis, a first end and an opposite second end. A central passage is defined through the cylindrical body and is centered about, and extends, along the longitudinal axis between the first end and the second end. The central passage has a circular cross section when viewed along the longitudinal axis. The limit ring further includes a number of channels defined in the cylindrical body radially outward from the central passage, each channel extending between the first end and the second end of the cylindrical body.
