Abstract: Disclosed is a main liner for a centrifugal pump having a main pumping chamber, the main liner being located within an outer housing of the centrifugal pump, when in use, and comprising: a main pumping chamber; an inlet opening for the introduction of a liquid into the main pumping chamber; a discharge outlet extending from the main pumping chamber; and an outer surface of the discharge outlet for contact with the outer housing for the liner, the outer surface having at least one alignment portion for engaging with a corresponding alignment portion on the outer housing, the engagement of the alignment portion with the corresponding alignment portion limiting movement of the discharge outlet relative to the outer housing.

Abstract: There is provided a drive side liner for a centrifugal slurry pump, wherein the centrifugal slurry pump includes an outer casing, a main liner and an impeller driven by a drive shaft, wherein the main liner and drive side liner are housed within the outer casing of the centrifugal slurry pump, the drive side liner including: an inner liner portion including a central aperture configured to receive the drive shaft, the drive side liner further including an outer liner portion arranged to surround the inner liner portion, wherein the inner liner portion and the outer liner portion are each configured to removably engage with one another and the outer casing.

Abstract: A method of producing a composite metal article and/or a composite metal wear component. The method including the following steps: casting a component composed of a host metal composition wherein one or more cavities are formed in the component during casting; inserting a wear resistant composition in solid form into the one or more cavities formed in the component composed of the host metal composition; and, bonding the wear resistant composition into the one or more cavities of the component composed of the host metal composition to form the composite metal article.

Abstract: Described is a wear part for minerals processing equipment. The wear part comprises an inner surface for contact with slurry when the minerals processing equipment is in use and an outer surface of the wear part. The wear part further comprises at least one sacrificial wear sensor located at a predetermined distance between the inner surface and the outer surface, the at least one sacrificial wear sensor being arranged to wirelessly communicate with a remote wear monitoring unit.
