Best 120gph pump to pull water/air

[SantaMonica]

I'm looking for an external pump to use for spill cleanup, meaning it would pull water off the floor and then push it to a drain. About 120 gph seems good. No real height needed, just about 20 feet of horizontal run, using 1/2" tubing, and needs to be ok when pulling air when the water runs out. What pump has a strong pull for this?

The Sicce Zero has worked well for me, but I’ve never tried it on a mixed water/air surface like the floor.

The Zero looks very good. I'm sure that dry operation is taken into account. I'm also looking at bilge pumps, but they don't go down to 2mm like the Zero does.

Darn the Zero says it cannot run dry
