What are the two pump styles?

• A. Inline and Submersible
• B. Close Coupled and Frame mounted
• C. Horizontal and Vertical
• D. Single-stage and Multi-stage

Answer: (A)

This item is testing understanding of how pumps are categorized by installation style in sewer systems. An inline pump is designed to be mounted directly in the flow path of the piping, fitting between sections of pipe with flange connections so the pump becomes part of the pipeline itself. It often remains dry and is not meant to be submerged. A submersible pump, on the other hand, is built to operate while fully submerged in the liquid, with the motor sealed and protected inside the wet well or sump. This setup allows pumping from beneath the surface without a separate dry housing. These two represent distinct installation approaches: inline focuses on integrating the pump into the piping run, while submersible emphasizes operation while submerged in the liquid. The other options describe different aspects that aren’t considered pump styles in the same sense—how the pump is mounted (close coupled or frame mounted), the orientation of the pump (horizontal or vertical), or the internal design (single-stage or multi-stage).
