Dosing Pump Guides
What a dosing pump is, how the name relates to metering pump, how it works, and how to size, calibrate and maintain one. No prices and no invented duty.
What Is a Dosing Pump
A dosing pump meters a repeatable volume of chemical. On this site it is the same class of machine as a metering pump. No price and no duty figure on this page.
Dosing Pump vs Metering Pump
Metering pump is the usual US name. Dosing pump is just as common in Europe and the Middle East. On this site they are one list. The drive is what changes.
How a Dosing Pump Works
A diaphragm or plunger displaces a chamber. Check valves set the direction. Stroke length or stroke rate sets the flow. This page states no stroke volume.
How to Size a Dosing Pump
Size a dosing pump from the chemical, the flow and the back pressure. Use the selector to shortlist. Series ends on a card are not one duty point.
How to Calibrate a Dosing Pump
Calibrate an installed dosing pump with a calibration column or a timed drawdown, using the sheet that ships with the pump. This page has no stroke table.
Dosing Pump Maintenance
Diaphragms, check valves and seals are the usual wear parts. Spare kits on the support page name the models they fit. The interval there is the kit note.
Dosing Pump Troubleshooting
First checks for no flow, low flow and a leak on a dosing pump. This is not a repair procedure. For a named model, use the support page.
