Difference Between Sewage Pump And Sump Pump

Comparisons, Knowledgebase

Last Updated on November 25, 2022 by mdmtool

Whether you’re a homeowner, business owner, or municipal employee, you may need a sewage or sump pump at some point. Although these two types of pumps may appear very similar, they are pretty different.

Sewage pumps are designed to handle larger volumes of fluid and solids and can typically handle up to 3 inches of solids. They are also built to withstand more wear and tear and can run for extended periods.

On the other hand, Sump pumps are designed to pump smaller volumes of fluid and are not built to handle as much wear and tear.

So, when choosing between a sewage pump and a sump pump, it’s essential to consider the volume of fluid and solids that need to be moved, as well as the level of durability and lifespan you need.
