septic lift station
I've installed commercial/industrial ones that were quite a few miles from anything. There's really no limit.
It depends on what you're trying to accomplish. Are you pumping raw sewage uphill to a septic tank? Effluent uphill to a drainfield? Raw sewage into a force main (pressurized main)?
Generally speaking, pumps like this are not rated in PSI, but feet of head. 2.31 feet of head = 1 PSI.
Figuring the pump capacity can be a somewhat complex equation, for a small system some of the factors can be estimated.
If you can give us a bit more info, we can help you choose a system that'll work well.
