Bottom Entry Agitator Mixer

Bottom Entry Agitator Mixer

Selecting the perfect bottom entry agitator for a given process requires a thorough understanding of your specific needs and the various factors that influence agitator performance. Wahal’s expertise can help you with this. Here’s a breakdown of the key steps to ensure you choose the right one:

  1. Define Process Requirements:
  • Mixing Objective: What is the primary goal of agitation? Is it blending, solid suspension, gas dispersion, heat transfer, or a combination?
  • Fluid Properties: Understand the viscosity, density, and any non-Newtonian behavior of the fluid.
  • Vessel Size and Shape: Consider the dimensions and geometry of the tank or vessel.
  • Operating Conditions: Know the temperature, pressure, and any potential corrosive or abrasive environments.
  1. Choose the Right Impeller:
  • Flow Pattern: Match the impeller type to the desired flow pattern (axial, radial, or mixed).
  • Viscosity Range: Select an impeller designed for the fluid’s viscosity range.
  • Shear Sensitivity: If the product is shear-sensitive, choose low-shear impellers like anchor or helical ribbon.  
  • Solids Handling: For solid suspension, consider high-flow impellers like turbines or pitched blades.
  1. Determine Agitator Configuration:
  • Number of Impellers: Larger tanks may require multiple impellers for effective mixing.
  • Impeller Placement: Impeller position and spacing influence flow patterns and prevent dead zones.  
  • Shaft Design: Choose a shaft material and seal compatible with the process fluid and operating conditions.
  • Drive System: Select a motor and gearbox combination to deliver the required power and speed.
  1. Consider Additional Factors:
  • Cleanability: Ensure the agitator design allows for easy cleaning and maintenance.
  • Material Compatibility: Choose materials that resist corrosion and contamination from the process fluid.  
  • Safety: Implement appropriate safety features for hazardous environments.
  • Cost: Factor in both the initial investment and long-term operating costs.
  1. Consult with Wahal
  1. Validate with Testing at Wahal
  • Pilot-Scale Testing: Conduct pilot-scale testing with Wahal with different agitators to validate performance and optimize design.

Important Tips:

  • Don’t Oversize: An oversized agitator can lead to excessive energy consumption and potential product damage.
  • Don’t Undersize: An undersized agitator won’t provide sufficient mixing, impacting process efficiency.
  • Consider Future Needs: Choose an agitator that can accommodate potential future changes in process parameters.

By carefully considering these factors and consulting with experts, you can select the perfect bottom entry agitator to achieve your desired process outcomes efficiently and reliably. Remember, the ideal agitator is the one that balances performance, efficiency, and cost-effectiveness for your specific application.Please feel free to contact wahal for more information.
