Size Your Own Eductor with the JT Eductor Sizing Tool

Sizing an eductor for your specific application used to require contacting a sales engineer or working with detailed specification sheets. Now, Jacoby-Tarbox has simplified the process with an online eductor sizing tool that lets you specify and size your own eductor application in minutes.

What Are Eductors?

Eductors (also called jet pumps or ejectors) are simple, reliable fluid-handling devices with no moving parts. They use the momentum of one fluid to move or mix another fluid.

Common applications include:

• Pumping liquids where a motor-driven pump isn't practical

• Mixing fluids for blending or chemical reactions

• Agitation in tanks or vessels

• Creating vacuum for degassing or dewatering

• Moving slurries or high-solids content fluids

Eductors excel where conventional pumps fail — they handle abrasive materials, work with corrosive fluids, and eliminate complex machinery in harsh environments.

Why Online Sizing Matters

Traditionally, engineers had to:

• Calculate flow rates, pressure drops, and density relationships manually

• Work through complicated vendor documentation

• Call for quotes before knowing if a standard size would work

• Wait days or weeks for engineering support

The online sizing tool changes this. You input your application parameters and get instant results.

How to Use the JT Eductor Sizing Tool

Step 1: Access the Tool Go to the Jacoby-Tarbox online sizing calculator at: http://eductors.clarkreliance.net/login.php

Step 2: Enter Application Parameters

• Motive fluid (what drives the eductor — usually compressed air, steam, or pressurized liquid)

• Suction fluid (what you're moving)

• Desired flow rate (GPM)

• Inlet pressure (on the motive side)

• Suction pressure (vacuum required)

• Fluid properties (density, viscosity)

• Temperature

• Connection type (in-line or in-tank)

Step 3: Get Results The tool calculates:

• Eductor model and size

• Pressure drop through the system

• Expected flow performance

• Connections and materials recommended

Step 4: Download Specs Export the specification sheet or CAD drawing for your sized eductor.
