Rotating elements that add head to the propellant. The inducer suppresses cavitation ahead of the impeller.
What decides the purchase: Head rise · flow rate · shaft speed · suction specific speed · NPSH required
Typical materials: Titanium 6Al-4V, Inconel 718, aluminium for low-temperature service
Typical processes: 5-axis machining, investment casting, additive
What changes when it has to fly: Cryogenic service and cavitation margin dominate design. Blade surface finish directly affects efficiency.
