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?

I'd suggest a Shop-Vac over a pump; they're extremely efficient and you can then just empty the receptacle.

I think a vac would overfill, and shut off. It needs to be automatic, with a water sensor switch that I'll connect.

You talking one of these? Sucks down to 2mm.

I was just looking at that one. And also some bilge pumps. But the Zero looks good.

Darn the Zero says it cannot run dry

Where is the water coming from?

No pump can run dry. I thought you were controlling it with a sensor?

A leak from the rain. But some pumps can run dry, and say they will self prime.

I was tired of having to dip my hands in my tank because the tubes on these gravel vacuums were too small! This Hygger aquarium water changer is the perfect size for my 10-gallon and I’m sure would do wonders on larger tanks too! Suction power is great too!
