The Ace lobe pump has a double spiral rubber rotor, which meets the needs of most stations in terms of self-priming; in terms of dry running, the Ace lobe pump structure is designed with a separate intermediate isolation chamber containing a light lubricant that lubricates the mechanical seal, thus allowing the lobe pump to run dry for short periods of time in the absence of material.
