RTM Custom Tank Mixing Eductor Manifolds

Efficient, No-Moving-Parts Solution for Uniform Tank Mixing and Agitation

Product Overview

Tank Mixing Eductor Manifolds are engineered systems that combine multiple tank mixing eductors into a pre-assembled manifold for rapid installation and optimized fluid circulation. Using the Venturi principle, these manifolds create powerful jets that entrain and multiply tank liquid flow—typically circulating 4–6 times the pumped volume—without mechanical agitators, impellers, or compressed air.

They ensure thorough blending, prevent stratification, suspend solids, and maintain uniform temperature, pH, and concentration throughout the tank. Ideal for large or irregularly shaped tanks where single eductors may leave dead zones.

RTM Custom Tank Mixing Manifolds

Key Applications:

  • Chemical processing and blending (acids, bases, solvents, slurries)
  • Wastewater treatment and pH adjustment
  • Food & beverage ingredient mixing and cleaning solutions
  • Oil & gas (drilling muds, fracturing fluids)
  • Plating, etching, and metal finishing tanks
  • Paint and coating preparation
  • Bulk storage and batch processing vessels
  • Agricultural chemical mixing (e.g., fertilizer or pesticide tanks)

How It Works

  1. Pressurized motive liquid (from a pump) enters the manifold and is distributed to multiple eductors.
  2. High-velocity jets exit each eductor nozzle, creating a low-pressure zone via the Venturi effect.
  3. Surrounding tank liquid is entrained (drawn in) at a ratio of 3:1 to 5:1 or higher.
  4. The combined flow is discharged at high volume, creating strong circulation patterns that sweep the tank bottom and eliminate settling or layering.

Result: Superior mixing with minimal energy input and zero maintenance from moving parts.

Features & Benefits

  • High Entrainment Ratio — Circulates up to 5–6× the inlet flow for efficient turnover.
  • No Moving Parts — Extremely reliable with virtually no maintenance or downtime.
  • Manifold Design — Pre-engineered distribution for even coverage; reduces piping complexity and installation time.
  • Corrosion & Abrasion Resistance — Available in durable materials for harsh chemicals and slurries.
  • Clog-Resistant — Flow-through chambers minimize plugging from solids or particulates.
  • Energy Efficient — Lower pump horsepower required compared to mechanical mixers or air sparging.
  • Flexible Placement — Mount near tank bottom for maximum agitation; customizable spacing (typically 12″ apart) for uniform flow fields.
  • Scalable — Manifolds can incorporate multiple eductors to suit tank size and shape (cylindrical, rectangular, or elongated).

Additional Advantages Over Traditional Methods:

  • Lower operating costs than propeller or paddle agitators.
  • No risk of mechanical failure or contamination from lubricants.
  • Better performance with viscous fluids, suspensions, and stratified layers.
