Segmented impeller channels prevent particle lodging while cement grooves strengthen the shaft connection.
- Nuclear Reactor Pump Diffuser Axial Alignment
Groove-tenon axial alignment eliminates studs to prevent stress corrosion cracking in nuclear reactor heat-transfer pumps.
- Centrifugal Pump Molten Metal Delivery System
Centrifugal pump delivers molten metal to die-casting molds, eliminating tube degradation and leakage issues.
- Composite Fan Containment Case with Metallic Backing
A composite fan containment case uses a metallic backing plate to enable secure bolt attachment for gas turbine engine components.
- Recessed Impeller Vanes Double Curvature Vortex Control
Double curvature vanes eliminate end vortices and reduce wear while generating a coherent vortex for improved pumping efficiency.
- Variable Speed Pump Torque Control for Fluid Density
A variable speed pump system regulates rotational velocity by monitoring motor torque to maintain stable operation across varying fluid conditions.
- Submersible Pump Reversible Plate for Solid Particle Evacuation
A submersible pump uses a reversible plate to configure flow channels for either clear liquid or solid-laden fluid evacuation.
- Solid Feed Pump Thermal Management via Coolant Paths
Internal coolant paths in a solid feed pump divert heat from the housing and rotor, extending component lifespan while enabling use of standard materials.
- Pump Pressure Relief Shearing Element
A pump pressure relief arrangement uses a shearing element to move a side wall section, preventing overheating and blockages in slurry pumps.
- Epicyclic Gearbox for Natural Gas Compressor Systems
Replacing parallel-axes gears with an epicyclic design reduces footprint and lubrication complexity while maintaining high compression efficiency.
