Chemical Dosing Pump Calculator
Dosing-pump flow to hit a target ppm in a process stream from stock-solution strength.
Size the metering pump so the duty lands at 30–70% stroke — full-stroke running leaves no headroom and tiny strokes lose accuracy.
Formula
Chemical Dosing Pump Calculator is a free dosing pump calculation for pump engineers, plumbers and plant designers — instant, accurate and 100% client-side, with the governing formula and reference shown next to the result so the number can be defended, not just quoted.
About Chemical Dosing Pump Calculator
Dosing-pump flow to hit a target ppm in a process stream from stock-solution strength. The calculation implements Q_dose(L/h) = Q(m³/h) × dose(g/m³) / C_stock(g/L) (AWWA — water treatment chemical feed practice). Size the metering pump so the duty lands at 30–70% stroke — full-stroke running leaves no headroom and tiny strokes lose accuracy.
How to use Chemical Dosing Pump Calculator

Frequently asked questions
What formula does the Chemical Dosing Pump Calculator use?+
It computes Q_dose(L/h) = Q(m³/h) × dose(g/m³) / C_stock(g/L), per AWWA — water treatment chemical feed practice. The formula is displayed under the result along with a worked example substituted with your own inputs.
What should I keep in mind when using this calculator?+
Size the metering pump so the duty lands at 30–70% stroke — full-stroke running leaves no headroom and tiny strokes lose accuracy.
Can I use this for pump selection?+
Use it to establish the duty (flow, head, NPSH, power) and then pick a pump whose curve passes through that point near best efficiency. The tool gives you the engineering numbers a supplier will ask for.
Is the Chemical Dosing Pump Calculator free to use?+
Yes — completely free, no sign-up, no limits. It runs client-side in your browser, so inputs stay private and results are instant even on slow connections.
