Three centrifugal flow pumps; the Biomedicus BP80, the Sarns Delphin and the Aries Lifestream 2100, were evaluated in vitro to determine each pump's individual tendencies for thrombus formation. Thrombogenic surfaces in the circuit were minimized by using heparin coated tubing and connectors. The centrifugal pumps, which were not heparin bonded, were placed in line in a circuit which consisted ...

Inducer is often used to improve the cavitation performance of pump. In order study characteristics inducer under low flow condition high-speed pump, photography technology was employed in this paper carry out visual experiments on a centrifugal rates, Cavitation distribution and evolution among were captured. The experimental results revealed that band-shaped backflow vortex inlet pipe would o...

In this paper, the performance of A1515 centrifugal pump was studied on a high parameters and precision large general test platform in combination with Huang-jin-xia hydro-junction Hanjiang-to-Weihe River valley water diversion project. The efficiency characteristics cavitation were tested measured respectively. All collected recorded through acquisition system. experimental results show that o...
