Pumps and their Applications

Lift Station Submersible Pumps

Lift Station submersible pumps, pumping raw untreated wastewater may include

upgraded impellers with sharp edges designed to chop rags and debris. This

feature helps lift station process commercial, institutional, or industrial materials

that could jam the pumps.

Submersible pumps must be routinely lifted from the wet well, visually inspected

and cleaned. It is important to keep a lift station wet well free of accumulated

sediment and surface grease, which can interfere with pump off/on controls and

in doing so, could burn out a submersible pump.

Submersible pumps can also be utilized within a pipe and not just in a wet well.

In line submersible pumps are becoming a common design application and can

be cleaner and more reliable than a standing pump exposed to corrosion and

weather.
