Eductor sizing calculator

Determine the size and number of eductors required based on your tank configuration, volume and the number of turnovers required.

* Required field

Not sure?

  • For light/mild agitation, use 5-15 turnovers
  • For average agitation, use 15-25 turnovers
  • For heavy agitation of solutions with high particulates or viscous solutions, use 30-50 turnovers

Rule of thumb

Eductors are usually spaced 1ft apart, 1ft from the bottom and pointed in the desired flow direction.

* Consult performance chart to select eductor size that best matches desired flow rate.

The total inlet flow rate per eductor is

GPM LPM
