The terms dispensing and dosing pumps are often used interchangeably, leading to confusion. And then we also have metering and transfer pumps to consider. While there is significant overlap - many pumps suitable for dispensing are also excellent for dosing - there are key differences in their precision, application, and control.
Here we summarise these differences and, most importantly, provide links to the most appropriate pump technologies for each category on our website.
| Dispensing Pump | Dosing Pump | Metering Pump | Transfer Pump | |
|---|---|---|---|---|
| Purpose | Precise, controlled delivery of set volumes | Continuous or intermittent injection of fluids | Highly accurate fluid delivery, often proportional to system requirements | Moving liquids from one place to another |
| Accuracy | High precision, repeatable volumes | Consistent dosing over time | Extremely precise, often adjustable | Low precision, prioritizes flow rate |
| CV (Coefficient of Variation) | <1% (Very high precision) | 1–5% (Good precision, depending on system) | <1% (High precision, often <0.5%) | >5% (Low precision, variable output) |
| Applications | Medical, lab, pharmaceutical, food, and beverage | Water treatment, chemical injection, industrial processes. Chlorine dosing pumps, chemical feeders | Chemical processing, pharmaceuticals, fuel injection | Bulk fluid movement, fuel transfer, wastewater handling |

Focused on delivering precise, repeatable volumes, commonly used in laboratory, pharmaceutical, and biotech applications.
Dispensing Very low CV (<1%), ensuring highly accurate and repeatable fluid delivery.
Designed for chemical and water treatment applications, ensuring accurate and repeatable delivery of fluids over time.
Dosing Pumps Moderate CV (1–5%), with accuracy depending on the pump type and control system.
Used in critical applications where highly accurate and adjustable flow control is required.
Metering Pumps Very low CV (<1%), ensuring highly accurate and repeatable fluid delivery.
Designed to move large volumes of fluid efficiently, prioritising flow rate over precision.
Transfer Pumps Higher CV (>5%), prioritising volume over precision.
Fluid Metering have recently updated their product catalog this year, should you have any questions about any of these products please let us know.
