[Maintenance Service Case] Repair of Slurry Circulation Pump Casing using BY933 Primer BY922 Repair Agent
DeviceName：
pump casing
DeviceProblem：
The primary reason is that the slurry contains a large amount of solid particles (fly ash, limestone, gypsum, particle size 20–60 μm, concentration 5%–28%), which erodes the pump casing inner wall, volute, and splitter at high speed. The slurry is acidic (pH 5–6) and has high Cl⁻ levels (up to 80,000 mg/L), creating a highly corrosive environment. Long-term operation has caused severe damage to the pump casing inlet ring and splitter, requiring on-site repair.
