1. Precision Hydraulic Design
Open impeller + optimized flow paths → NPSHr≤1.5m at 3,000 rpm without an inducer (NPSHr 40% lower than standard OH2 pumps);
Axial force auto-balancing: Sector-vane impeller design and its 0.8~1.2mm clearance with pump casing neutralize 95% axial thrust → ≤2.5mm/s vibration at 1 m³/h ultra-low flow.
2. High Reliability and Ease of Maintenance
Centerline support structure: 3× API 610 nozzle load capacity → extends seal life by 60%;
Back pull-out design: Seal/bearing replacement in 45 minutes without pipe disassembly (70% faster maintenance).
3. Full-Range Adaptability
Tungsten carbide coating (≥HRC65) reduces wear rate by 50% for ≤50μm solids (≤1% concentration);
API 682 cartridge seals for corrosive/flammable media;
Performance coverage: 1~28 m³/h flow | 8~400m head | 11.0MPa design pressure.
