Smaller pumps, manageable by two people, typically offer a runtime of up to 3-4 hours when powered by diesel. To extend this operational duration, you can attach an extra diesel tank to the pump, effectively doubling the runtime from 3 to 6 hours.
High-volume pumps come equipped with larger tanks but are not intended for manual lifting. It’s crucial to emphasize that all pumps, regardless of their capacity or fuel type, should be continuously monitored during operation.
