Circulation rate is the volume of liquid pumped by the impeller per unit time. In industrial mixing, this parameter should be reviewed along with tank geometry, impeller type, fluid properties and operating objective.
Common Applications
- Tank turnover
- Bulk blending
- Heat transfer
- Solid suspension
Selection Factors
Correct selection depends on the process objective and site conditions. For Circulation Rate, Premix usually reviews these points before recommending equipment:
- Nq = flow number
- N = revolutions per second
- D = impeller diameter
Why It Matters In Plant Operation
Circulation Rate affects process stability, chemical usage, equipment life and final output quality. A correctly selected solution helps reduce trial-and-error at site and supports more predictable daily operation.
