When using a rotary lobe pump for self-priming, the permissible dry working time of the pump is an important evaluation indicator. At the beginning of pump operation, there is no medium in the pipeline, so the pipeline from the pump inlet to the medium layer needs to be pumped to form a negative pressure. This requires that our pumps have a certain dry running capability or that certain measures are taken to avoid dry running of the pump. Our Ace rotary lobe pumps can run from 0 to 30 minutes.
