The design of the pumping system fits the operation requirement well not only theoretically but also experimentally. The data showed that the averaged pellet injection velocity and propellant gas pressure had a relationship submitting to the power function. The reliability of the injected pellet was mostly around 90% which is higher than the PI-20 system thanks to the improved pumping system and the new pellet fabrication and acceleration system.
