650 Pump Optimization for a Copper Concentration Line

Project Background

A large 650-class pump feeding a copper concentration line was consuming wear parts at a rate that    placed steady pressure on the maintenance budget. The installed pump itself was sound; the issue was    the combination of part grade, operating point and the actual slurry it was seeing.

Review & Supply

• Re-evaluated the liner material grade and impeller profile against the real operating duty rather than the original nameplate

• Specified a high-chrome wet-end set for the most abrasive part of the curve

• Recommended running the unit nearer its stable window where the process allowed, within the existing installation

• Delivered a complete wet-end set plus a spare impeller so the first service could be completed without a second order

Result

Over the following operating period the maintenance team recorded longer intervals between impeller    changes on the 650 pump, and the parts cost per tonne processed came down. The optimized set is now the    site's standard repeat order for that pump.
