Pistonless pump technology developed by Flometrics, Inc., shows considerable promise in eliminating these roadblocks by pressurizing and pumping rocket propellants without the use of any rotating machinery or physical pistons. This is achieved through the use of two pressurized "pump chambers" that alternate pressurizing and draining of the propellant. Unlike traditional rocket turbo-pumps, which are extremely sensitive to high vibration environments and two-phase flow, the pistonless pump design features no moving parts aside from valves commonly used in microgravity space fluid applications.
An industry-university partnership has been created to develop a full capability pistonless pump test apparatus for testing on a commercial suborbital vehicle. The proposed working fluid will be a simulated cryogen, carbonated water, which exhibits many of the difficulties encountered when pumping a cryogenic propellant near saturation, without problems associated with safety.
