Pump Impellers — Municipal Water System Upgrade

We produced 300 enclosed impellers in CD4MCu duplex stainless steel for a municipal water treatment plant pump upgrade. The impellers required precise vane geometry and dynamic balancing to G2.5 standard.

  • Material: CD4MCu (Duplex SS)
  • Impeller diameter: 200-400 mm
  • Dynamic balance: G2.5
  • Surface finish: Ra 3.2 μm on flow surfaces
  • Quality: 100% PT + dimensional inspection
  • Application: Horizontal split-case pumps

Chemical Pump Casings — Sulfuric Acid Plant

High-alloy pump casings for sulfuric acid service required exceptional corrosion resistance and precise dimensional control for seal face flatness.

  • Material: CN7M (Alloy 20)
  • Part weight: 45 kg
  • Corrosion test: ASTM G48 (pitting)
  • Seal face flatness: 0.05 mm
  • Pressure test: 1.5x working pressure
  • Result: 3+ years service life, zero leaks
