Mixer Torque Pre-Sizing
Calculate the required torque from your tank, product and impeller data — the real process need, not the motor nameplate.
Every question can be answered by a plant engineer by looking or measuring with a tape. The result is a pre-sizing; final motor selection is confirmed by EMF engineering.
What is the purpose of mixing?
What is being mixed?
Pick the closest match. The calculation always uses the worst case (coldest, thickest).
Are there solids in the product?
Select the impeller type
Pick the drawing that looks most like your impeller.
Measure tip to tip. A 10 cm error changes the result significantly — measure, don’t guess.
Tank dimensions
Operating conditions
Speed of the impeller shaft — from the gearbox output or the drive display.
If you know your existing system (optional, for comparison)
We show the installed torque next to the calculated real need.
