Pneumatic capsule pipeline (PCP) uses wheeled capsules (vehicles) to carry cargoes through a pipeline filled with air. Modern large diameter PCP systems utilize through flow booster pumps, also known as jet pump injectors. These create the pressure differentials required to propel multiple capsules through a pipeline, while allowing both terminals at atmospheric pressure. This is done by placing a booster pump midway along the pipeline, and designing it in such a way that capsules can bypass the pump.
