Which option is NOT a pump type discussed in the material?

• A. Rotary Pump
• B. Reciprocating Pump
• C. Centrifugal pump
• D. Diaphragm pump

Answer: (D)

This item tests your ability to recall which pump types were covered in the material. The material discusses three main pump types: rotary pumps, which use rotating parts like gears or lobes to move fluid; reciprocating pumps, which push fluid with a piston or plunger in and out to deliver a fixed volume per cycle; and centrifugal pumps, which use an impeller to create flow through dynamic pressure. A diaphragm pump is a valid pump type that uses a flexible membrane to displace fluid, but it isn’t described in the material. Since it isn’t part of what you were given, it’s the option that doesn’t fit with the discussed content.
