Packing & Shipping

  • Casting/Forging: Pump body, impeller, and diffuser are made using precision casting (ASTM A351/CF8M for 316SS) or forging for high-load components. Bronze or duplex alloys are used for challenging environments (e.g., seawater, mining).
  • CNC Machining: All sealing interfaces and dynamic points undergo CNC tolerance control (within 0.017mm), ensuring minimal vibration and stable long-term operation (Mean Time Between Failures ≥ 18,000 hours).
  • Surface Treatment: All flow channels are polished or epoxy coated; stainless steel models use electropolishing for increased corrosion resistance.
  • Hydraulic Testing: Each pump passes a performance & pressure test per ISO9906 Grade 2B. Sample batch vibration and sound-level analysis confirm smooth, silent running.
  • Final Inspection: Each unit includes unique QC traceability, certified to ISO9001/CE/WRAS.

4. Technical Advantages & Industry Certifications

  • High Efficiency: Custom hydraulic impeller design reaches up to 82% pump efficiency, a leading level per ISO9906.
  • Certified Durability: Test data from a 2022 field study (Shaanxi, China) showed a 5-year failure-free rate of 97.4% in full-time operation. All series compliant with ISO9001, CE, and WRAS.
  • Advanced Material Options: Model variants offered in 316L stainless steel, bronze, and high-chrome cast iron for the toughest water chemistries and abrasive wear environments.
  • Deep Well Compatibility: Supports well depths up to 300m, with stable sealing, balanced axial force, and minimal energy consumption (≤7.6 kWh/100m³ water delivered).
  • Anti-corrosion & Anti-abrasion: Double mechanical seals, specialized bearings, and non-toxic polymer coatings ensure stability in high-saline/acidic applications (tested to ASTM B117 salt fog for 720h+).
  • Integrated Motor Protection: Built-in temp probe and overload relay per IEC60034 extend service life, reduce accident risk.

5. Application Scenarios
