A400 Double Spiral Impeller

Overview

The A400 Double Spiral Impeller is engineered for complete tank turnover and enhanced thermal performance. Its dual-blade configuration and close-clearance design make it ideal for jacketed vessels and applications requiring efficient mixing and heat transfer.

Key Features

  • Dual-blade design:
    • Inner blades pump downward
    • Outer blades pump upward
    • Creates full circulation and turnover of tank contents
  • Close-clearance operation improves heat transfer in jacketed vessels
  • Superior to open-style impellers like A200 (pitch blade turbine) and A320 (wide-bladed hydrofoil)
  • Bolted construction available for tanks with small-diameter manways
