How often should refractory pump wear parts be replaced?

Material valves, cylinder liners, and hoses should be tracked against cumulative tonnage pumped rather than a fixed calendar schedule, since wear is driven by material abrasiveness and volume handled, not time elapsed. Coarse or angular aggregate castables accelerate wear considerably compared to fine, rounded aggregate mixes. Sparkline Group helps clients set up tonnage-based replacement triggers and stocks genuine wear parts to support this approach. This method catches wear before it causes an unplanned mid-shift failure.
