Axial Impellers for High-Efficiency Mixing

Optimized for Homogenization, Heat Transfer, and Wastewater Treatment

Milton Roy Mixing’s axial impellers deliver exceptional pumping rates and low power dissipation, making them ideal for applications requiring gentle yet efficient blending.

Designed for floating, top-entry, and side-entry mixers, these impellers handle low to medium viscosity fluids and ensure uniform mixing for processes like homogenization, solid suspension, and heat transfer.

A flow is described as axial when the liquid discharge has a predominantly axial direction.

Generally, the impeller blows the liquid towards the bottom of the tank, where it then rises along the tank wall, creating a continuous circulation loop.

Axial-flow impellers are characterized by a blade angle that is slightly inclined relative to the horizontal plane, promoting efficient top-to-bottom mixing.

  • 10 SG SABRE: High pumping efficiency for large tanks
  • HPM Series (5, 10, 20): Versatile for mining, fertilizer, crystallization, solid resuspension
  • PBT: Axial and radial flow for reactive dispersion
  • HXP HP1 & HP2: High-speed designs for flash mixing, homogenization and vigorous agitation

Ready to Optimize Your Mixing Process?

Our experts can help you select the right axial impeller for your application.

 

Our axial impellers combine precision engineering with robust design to deliver efficient, low-shear mixing for a wide range of applications. From flexible blade configurations to optimized technical specifications, they ensure high pumping efficiency, process versatility, and long-term reliability.

Frequently Asked Questions about Axial Impellers

  1. What applications are axial impellers best suited for?
    Axial impellers excel in various applications: homogenization, heat transfer, solid suspension, crystallization, and wastewater treatment processes such as coagulation and flocculation.
    Technical Note: Ideal for tanks up to 20,000 m³ with low to medium viscosity fluids (up to 5,000 cP).
  2. Can axial impellers handle high-viscosity fluids?
    They are designed for low to medium viscosity; for > 5,000 cP, use special impellers like HPM.
  3. What is the main advantage of axial impellers over radial impellers?
    Axial impellers provide superior pumping efficiency and gentle mixing, reducing shear stress on sensitive products. They deliver better energy efficiency, combining high pumping rates and low power dissipation.
  4. Are axial impellers compatible with side-entry mixers?
    Yes, especially 4-blade configurations for large storage tanks (diameter up to 800 mm / 2.62 ft).
