Beschreibung
Zusammenfassung:	A gerotor device for a pump apparatus is disclosed. The gerotor device includes at least two gerotor stages that respectively include an inner rotor rotating during operation about an inner axis with teeth projecting radially outside, and an outer rotor rotating during operation about an outer axis radially offset relative to the inner axis with radially inner open tooth gaps, in which the teeth of the inner rotor engage. A rotor body rotating during operation about a rotor axis includes radially open tooth gaps of a first gerotor stage of the at least two gerotor stages and teeth projecting radially outside of a second gerotor stage of the at least two gerotor stages. The tooth gaps of the at least two gerotor stages are fluidically sealed at least one of against one another and relative to a surrounding area.
