Pump Performance with Sand Wear

In many installations, pump performance declines over time due to sand wear. In order to pinpoint the type and rate of wear caused by pumping water with higher-than-average sand concentrations and its direct effect on various pump impeller materials, vertical pump impeller/bowl assemblies of approximately 900 GPM were each pumped for up to 2500 hours with high concentrations of sand in the water. Two different impeller materials were used for a total of five configurations. Well pump operation was simulated by maintaining a constant discharge pressure. The degrading performance, in terms of changing flow rate and kilowatt load, was recorded over time.
