Question about Goulds LS & GS Pumps

[kirkdj]

Can anyone tell me the difference in the Goulds submersible pumps......   they have a LS series and a GS series.......I'm guessing the LS is a lesser quality pump because it's what the contractor used......does anyone know?

The working parts are all the same.  The GS just means it has a Stainless Steel discharge head and suction adapter.  I think LS is the model for brass head and suction adapter.  The internals are all plastic and are the same on all models.
