Abstract
A centrifugal impeller with a single inlet and dual outlets that include a low pressure outlet and a high pressure outlet. The impeller includes low pressure blades with high pressure blades located downstream. The impeller can be shrouded or unshrouded, and can include an inner shroud that forms a flow path for the low pressure fluid and a high pressure flow path for the high pressure fluid. The impeller can include a high pressure volute and a low pressure volute that forms a dual volute with dual diffusers for both fluids.
