Sump pump basins and sump pump covers contain the pump, float, and pipe inside the sewage pit.
This is a solid heavy duty sewage ejector.......probably weighs twice as much as similar made in China pumps I have been using and which have only lasted a couple of years.
I expect this to last several years like similar pumps I have used in the past.
