What is Dosing Rate?
The volume of chemical injected per unit time or per unit volume of process fluid, expressed in LPH or mg/L.
View Dosing PumpsDosing Rate Explained
Dosing rate (LPH) = Process flow (LPH) x concentration (mg/L) / chemical strength (mg/L). The dosing pump should operate at 60-80 percent of maximum output at design dose rate to retain adjustment range.
Common Applications
- Pump sizing calculation
- Chemical consumption estimation
- Control system setpoint
- Process optimisation
Selection Factors
Correct selection depends on the process objective and site conditions. For Dosing Rate, Premix usually reviews these points before recommending equipment:
- Process flow rate
- Required concentration
- Chemical solution strength
- Variation range required
Why It Matters In Plant Operation
Dosing 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.
