Abstract: Pitot tube pumps, which are high-lift and micro-flow,have better cost performance than high-speed pumps. The origin, the process of improvement, the structure, the working principle, the performance parameters and characteristics of pitot tube pumps are presented in this article, and by comparing with high-speed pumps, the advantages of pitot tube pumps are concluded. Pitot tube pump could be widely used in liquid transmission area instead of high-speed pumps due to its advantages in higher efficiency, lower speed, more steady operation performance, longer operational life and lower cost.
