Abstract: Methods of producing impeller castings from very hard materials are disclosed in which the formation of a selectively configured core produces an impeller casting that does not need to be machined to receive the drive shaft and eliminates the need for employing a lead babbitt or soft insert, as is known in the prior art, to receive the drive shaft, thereby producing a hard material impeller for a centrifugal pump that is significantly less costly to produce and is environmentally safe.

Abstract: In a centrifugal pump of the pitot tube type, a replaceable wear ring is positioned in the rotating assembly of the pump in that area of the rotating case which is most subject to erosion from the processing of abrasive fluids by the pitot tube pump. The replaceable wear ring can be easily and quickly replaced when eroded, thereby eliminating the need to replace the rotating case of the pump and eliminating the need for costly and time-consuming rebalancing of the pump.
