🔍 Key Concepts

• Centrifugal vs. positive displacement pumps – how fluid moves through each type • Shape and flow path in a volute casing around an impeller • Difference between axial flow and radial flow through an impeller

💭 Think About

• Look at the housing around the impeller: does it trap fixed pockets of liquid, or does it form a spiral passage that gradually widens? • Observe the direction the liquid would leave the center of the impeller: does it move mainly outward from the center, or straight along the shaft? • Which pump type relies on building velocity in the fluid and then converting it to pressure in a volute, rather than squeezing fixed volumes of liquid?

✅ Before You Answer

• Does the illustration show a spiral (volute) casing around the impeller? • Are there curved vanes throwing liquid outward from a central eye, instead of pistons, gears, or sliding vanes? • Confirm whether the design looks like it does NOT create sealed chambers of fluid (a sign it is not positive displacement).
