🔍 Key Concepts

• Positive displacement pumps vs. dynamic pumps and how they move fluid • Key parts of a centrifugal pump such as an impeller, volute, and suction/discharge nozzles • Visual differences between piston/diaphragm/reciprocating pumps and rotary pumps

💭 Think About

• Look at the main moving element in the illustration: does it move back-and-forth in a straight line, flex like a membrane, or spin around a shaft? • Examine the casing shape: is there a volute-shaped housing that gradually enlarges around a rotating element, or a straight cylinder for a reciprocating motion? • Consider how fluid would enter and leave this pump: is it trapped and pushed by a piston/diaphragm, or flung outward by rotation into a volute casing?

✅ Before You Answer

• Identify whether the picture clearly shows an impeller mounted on a rotating shaft • Confirm the presence (or absence) of cylinders, pistons, or diaphragms in the cross‑section • Note the volute-shaped casing and how discharge is taken off tangentially from the housing
