Q

The diffusion ring installed in many high pressure centrifugal pumps, such as feed pumps, __________.

🔍 Key Concepts

• Function of a diffusion ring (diffuser) in a high‑pressure centrifugal pump • Difference between where kinetic energy is added (impeller) vs where it is converted to pressure (diffuser/volute) • Sources of axial thrust and radial thrust in centrifugal pumps and typical ways they are controlled

💭 Think About

• Think about which pump component actually adds velocity (kinetic energy) to the liquid, and which component slows it down and builds pressure. • Ask yourself: Does a diffusion ring mainly deal with flow direction and velocity or with mechanical balancing of thrust on the shaft/impeller? • Consider whether using a diffusion ring would reasonably replace a double suction impeller, or if those two design features address different problems.

✅ Before You Answer

• Identify which part of the pump (impeller vs diffuser) is responsible for increasing fluid velocity. • Recall what design features are typically used to handle axial thrust (e.g., double suction impellers, balance drums, thrust bearings). • Recall what design features are typically used to reduce radial thrust (e.g., volute design, diffuser vanes, casing geometry).
