ABSTRACT:
The wear resistance of impellers used in multi-stage turbine pumps is tested by using a multi-stage turbine pump having impellers with different physical properties to pump a fluid containing small amounts of an abrasive material. After the fluid has been pumped for a time period sufficient to provide measurable wear to the impellers, the impellers are inspected to determine their relative resistance to wear.
