Digital dosing pumps, by contrast, come with a range of features that make them most suitable for automated plants or where higher levels of monitoring and control are required, including remote functions. Grundfos has been a pioneer of digital dosing for over 20 years.

“Automation functions are particularly valuable for companies who have plants in different parts of the country,” he says. “If loadshedding leads a pump to trip, for instance, an alarm will notify the user, and they can remotely reset and restart the operation.”

They are also preferred where accuracy of dosing quantities is prioritised, or where dosing volumes are very small. Some digital dosing pumps boast high turn-down ratios as low as 1:3,000, and can deliver pressures of down to 0,002 bar.

“They can even pick up leaks in the line, and will help prevent liquid losses by automatically alerting the operator,” he says.

The automatic de-aeration function is another valuable element in advanced digital dosing pumps, allowing them to detect and remove bubbles from a line. This is important as bubbles will impair the accuracy of dosing.
