A sewage pump (wastewater pump) moves water that contains solids, sludge or suspended material without clogging. Solids-handling size and impeller design are the key selection factors.
This guide covers the main wastewater pump types and how to choose one.
Types of sewage pumps
| Type | Description |
|---|---|
| Submersible sewage (WQ) | Sits in the sump; non-clog impeller for solids |
| Non-clog self-priming (ZW) | Above-water mounting, easy service, handles solids |
| Construction-site | Rugged self-priming for muddy, gritty water |
| Grinder | Cuts solids for pressurized sewer lines |
What sewage pumps are used for
Wastewater pumps serve municipal sewage, lift stations, industrial effluent, construction and treatment plants.
How to choose
Choose by required solids-passage size, flow and head, plus material resistance for corrosive or abrasive media. Submersible suits sumps; self-priming eases inspection.
Tip: Share your flow, head and application with a supplier to get the right size and configuration.

FAQ
Submersible or self-priming sewage pump?
Submersible sits in the sump and saves space; self-priming stays accessible for inspection and service.
What solids size can it pass?
Check the rated solids-handling diameter; match it to the waste the system will carry.
