Dolphin Pump model 77840

Does anyone know anything about the dolphin pump model #77840? I am trying to figure out the gph on them. I also have another one that does not work... i plug it in and nothing. Any ideas what may be wrong with it?

I think that pumps like 1250gph have you tried giving it a bump sometimes they free up if been sitting up awhile if not take front off impeller may be stuck or sand inside

just my thought if you drilled you sump and put a bulkhead in the side instead of drawing the water up it would be so much easier to prime pump .IMO

That looks very similar to the CSL/Poseidon/Velocity line of pumps.
