is there such thing as a pressure rated submersible pump?

[nickyblase]

I thought for sure I had talked to someone about this at one point or another, but I must be getting senile... can't find the thread anywhere.

Is there such thing as a submersible pump that's pressure rated? I need one to run my ETSS 800, and the design of my sump is not conducive to an external pump.

Any thoughts are appreciated!

None that I'm aware of.

That said, "pressure rated" isn't a term that is used consistently or that has a universal definition. Any pump will run under pressure, it's just a question of how it actually performs and at what amount of head/back pressure it will cut out and stop moving water. Regardless, I don't think you can get away from a beefy external pump to properly drive an ETSS skimmer.

For your sump design, could you have the pump placed externally at a right angle so it's parallel to the end of the sump? It's not ideal to have an elbow on the intake of a pump, but I've done it with Iwaki 55 and 70 "pressure" pumps and had no issues with cavitation or premature wear.
