ABSTRACT:
First turbine stage 14 rotates at low speed, doing moderate work, and driving a low pressure pump (22). Second turbine stage 16 rotates at high speed, doing a major portion of the work, and drives a high pressure pump (28). The low speed pump is compatible with suction requirements, and the second turbine stage does the substantial work at high efficiency.
