The following chart visualizes the rising technological specs for impellers over the past 5 years. Key metrics—efficiency, lifespan, and compliance—are steadily increasing, reflecting R&D investments and new composite materials.

4. Manufacturing Process for Impeller — Step-by-step Diagram

1. Raw Material Inspection (ISO/ANSI)
Certified metals (SS, bronze, alloys) analyzed for composition, purity. Only ISO 9001-accredited sources used.

2. Casting or Forging
Sand or investment casting, followed by heat-treatment. For high-end, CNC-forged impellers minimize voids.

3. CNC Machining
5-axis CNC ensures precision of <0.01mm—critical for cap ends and pump casing fit.

4. Surface Treatment
Anti-corrosive coatings or polishing (Ra ≤ 3.2μm), extending lifespan and pump efficiency.

5. Inspection & Balancing (ISO 1940/1)
Dynamic balancing (G6.3 grade) & ultrasonic flaw detection guarantee vibration-free performance.
