Slurry pump suction side liner with replaceable components

摘要

A slurry pump suction side liner with replaceable components is provided utilizing separate suction port assembly, wear ring assembly, wear plate assembly and backing plate assembly components connected together to form a rigid suction side liner for directing a slurry into an impeller inlet. A replaceable annular wear ring having a first wear resistant surface facing the inlet axis and a second wear resistant surface at right angles to the inlet axis is provided to maintain a predetermined gap between gap between the impeller and replaceable wear ring to prevent slurry flow between the impeller and suction side liner assembly. An annular wear plate assembly having a wear resistant surface flush with the second wear resistant surface on the wear ring assembly is also provided to extend the gap radially outward from the wear ring, which is positioned between a suction port and the impeller. The wear ring and wear plate are each made in sections so the suction side liner may be removed and replacement made of the suction port or individual sections of the wear ring or wear plate as abrasion on the components by the slurry takes place without necessity of replacing the entire suction side liner. The wear ring and wear plate wear resistant surfaces are made of wear resistant carbide.
