Dosing Pump Stroke Setting Calculator
Stroke % to set on a metering pump for a target dose rate.
Diaphragm metering pumps stay linear mid-range but drift at the extremes. Calibrate with a draw-down cylinder — nameplate capacity assumes rated back-pressure.
Formula
Dosing Pump Stroke Setting Calculator is a free dosing pump stroke 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 Dosing Pump Stroke Setting Calculator
Stroke % to set on a metering pump for a target dose rate. The calculation implements stroke % = Q_required / Q_max × 100 (API 675 — controlled volume pumps). Diaphragm metering pumps stay linear mid-range but drift at the extremes. Calibrate with a draw-down cylinder — nameplate capacity assumes rated back-pressure.

Frequently asked questions
What formula does the Dosing Pump Stroke Setting Calculator use?+
It computes stroke % = Q_required / Q_max × 100, per API 675 — controlled volume pumps. 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?+
Diaphragm metering pumps stay linear mid-range but drift at the extremes. Calibrate with a draw-down cylinder — nameplate capacity assumes rated back-pressure.
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 Dosing Pump Stroke Setting 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.
