PROBLEM TO BE SOLVED: To provide a rotary displacement pump capable of providing stable displacement without being influenced by accuracy of components and assembly, and capable of materializing high reproducibility of flow rate irrespective of drive types such as short period drive and continuous drive. SOLUTION: A drive control part 2 controls rotation quantity of a stepping motor M by pulse drive. Drive of the stepping motor M is controlled to set minimum delivery quantity of fluid to unit delivery quantity during one rotation of a drive gear 7 or a driven gear 8, or integral multiple thereof.
