In-Tank Eductor Mixing Systems

Venturi-MXR for Reliable, Efficient Fluid Handling

The PFS Venturi-MXR is a proven solution for tank mixing, agitation, and fluid conditioning. Using the Venturi effect—based on the Bernoulli principle—the system leverages fluid velocity and pressure differentials to entrain and circulate tank contents without moving parts inside the vessel.

For over 40 years, Primary Flow Signal has been a trusted leader in Venturi design, engineering, and manufacturing. The Venturi-MXR continues that tradition, providing efficient, reliable, and low-maintenance mixing for industrial, municipal, and hygienic applications.

Venturi Mixer Capabilities

Venturi-MXR systems are engineered to solve a wide range of process challenges:

  • Suspend Solids — to prevent settling in tanks or pipelines
  • Blend or Mix Fluids — of varying densities or compositions
  • De-stratify Layers — to eliminate gradients in storage or process vessels
  • Temperature Stabilization — by promoting uniform heat transfer
  • Accelerated Heating — through direct steam injection

Low Shear Mixing

Safe for sensitive compounds, live cell cultures, enzymes, and complex chemical processes.

High Turnover Efficiency

Moves up to five times the pumped volume for accelerated tank turnover.

Improved Aeration & Heating

Produces smaller bubble sizes than spargers, increasing efficiency.

Process Optimization

Accelerates blending, reduces chemical usage, and increases cycle throughput.

Temperature Control

Often saves more than 50% of circulation time compared to conventional methods.

No Moving Parts

Eliminates internal mechanical wear, minimizing maintenance needs.

How the Venturi-MXR Works

The Venturi-MXR uses motive energy—recirculated fluid, secondary fluid, steam, or gas—introduced through a specially engineered nozzle. As the motive accelerates through the Venturi throat, it entrains a calculated volume of surrounding liquid and discharges as a high-momentum jet.

This discharge jet performs the mixing work inside the tank, achieving goals such as solids suspension, fluid blending, temperature control, or liquid de-stratification.
