What are the two basic propeller pump types?

• A. Axial Flow and Mixed Flow
• B. Diaphragm Pump
• C. Submersible Pump
• D. Centrifugal

Answer: (C)

Propeller pumps use two main impeller designs that define their performance: axial flow and mixed flow. In an axial flow design, the blades push fluid mainly along the pump’s axis, producing very high flow with relatively low head. This makes them ideal for moving large volumes of water or wastewater with minimal lift. Mixed flow blades combine axial and radial components, delivering more head than axial flow while still maintaining a strong flow rate, so they’re suited for applications needing more lift without sacrificing too much throughput. Other options describe different pump categories or configurations that aren’t defined by the propeller impeller style: diaphragms are a positive-displacement type, submersible refers to how the pump is installed, and centrifugal is a broad family that can include various impeller types, not the two basic propeller configurations.
