XS mining split-case double-suction pump project for Changsha Kuanghai Pump Industry ｜ Changsha, Hunan

Application scenario: long-term batch cooperation with Changsha Kuanghai Pump Industry. XS series split-case double-suction pumps with full assembly + wear-resistant casing + stainless wetted parts, integrated with Kuanghai VFD cabinets, bases, and explosion-proof accessories. Used in manganese, coal, and non-ferrous mines in Hunan, Guizhou, Sichuan, Yunnan. Covers mine drainage, beneficiation circulation cooling, tailings return, and domestic water supply. Mine water contains abrasive particles + weak acid/alkali + chloride corrosion + scaling; humidity 95%+ and dust cause rapid corrosion; flow fluctuation >40%; high energy loss due to throttling; limited maintenance windows; unstable power supply; old pumps efficiency 72%–76%, impellers wear out in 3–5 months, disassembly takes 6h+, no sensor interface for smart mining systems.

 

Solution content: XS500/600 (3600–4800 m³/h / 26–65 m / ≥87.2% / 10kV explosion-proof / 3 units 1 standby) main drainage; XS350/400 (1600–3200 m³/h / 30–60 m / 380V explosion-proof + VFD control) beneficiation/tailings; XS250/300 (800–2400 m³/h / 32–70 m) mine water supply. Quick split horizontal design reduces maintenance by 70%; double suction self-balancing axial force; interchangeable base with S-type pump 1:1; PT100/vibration sensor ready for smart mining system. Graded wear materials: 304 stainless for clean water, 2507 duplex for slurry, ZG20Mn casing + epoxy zinc-rich + humid corrosion coating, full stainless bolts; explosion-proof YE4 motors + electric tracing; CFD 3D impeller improves efficiency by 10–14%; VFD replaces throttling; water hammer absorber included. Local supply + onsite support + 2-year spares + quarterly inspection; compatible with remote monitoring cloud platform.

 

Project results: energy saving 23%–28%; major reduction in electricity cost; overhaul cycle extended to 12+ months; maintenance frequency reduced by 65%; downtime reduced by 70%; eliminates flooding risk; standardized interchangeability shortens installation time; rapid response capability for urgent orders.Replicable to mining equipment package suppliers in Xiangtan, Loudi, Tongren, Zunyi, and other areas across Hunan, Guizhou, and Chongqing.
