How do I troubleshoot pulsing or surging flow from my refractory pump?

Pulsing flow is often linked to air entrainment at the hopper from low material levels, or worn valve seats that no longer seal fully between pump strokes, both of which can cause segregation in the placed castable. Keeping the hopper adequately filled during operation and inspecting valve seats on a tonnage-based schedule addresses most cases. Sparkline Group's technicians can identify which of these is occurring and recommend the appropriate fix or replacement part. Addressing pulsing early protects both placement quality and pump component life.
