A 30' elevation change and a total distance of 150' ...... I would contact the mfg directly and ask them.
Moving the water is one thing.....having enough pressure/volume to do anything with it is something else.

Been a long time since I've done any friction loss calculations while running a fire pump or redesigning non-working irrigation systems but here are a couple of things to think about:
-the first thing to think about is friction loss which means how much more pressure you need to force the water through a container to achieve the pressure you need on the working end.
-the smaller the hose the higher the friction loss...friction loss on a garden hose is MUCH higher than say a 1 3/4" fire hose.
-hard pipe generally has a lower friction loss than "soft" hose because pipe is straight and smoother inside
-every bend, elbow, coupler, etc increases the friction loss
-depending on what size pipe you use you can probably use a general rule of thumb that you'll need an extra pound of pressure for every foot of elevation that you are trying to pump.
Probably should contact the pump manufacturer, tell them what pipe/hose/length/elevation you want to try to use their pump for and see what they say. Something tells me that you are really going to be working this pump with what you want to do.

I have not spoke with them yet. Just read several reviews on that pump where people were doing similar things with it. That pipe has a 1" outlet. I would run it 1" up the hill then split it to a garden hose with 1 or 2 springlers.
I would probably guess it closer to 25' than 30'.

Doubt it would have enough pressure to run 2, but you should be ok with 1. I used a 1.5 hp electric pump with about 300'ft of 1" hose and it would run 1 sprinkler. I now use a 5hp transfer gas transfer pump with 2" hose and reduce it down to 1". Depending on the distance it will run 2 and sometime's 3 sprinkler's at once.

I called the company and they calculated it for me. Enough pressure and flow to run 1 sprinkler. My other option is to pump it up to a holding tank then transfer the pump up the hill and run it from the holding tank. I could then run a couple of sprinklers. I would need to find a holding tank or several barrels. Anyone seen any cheap tanks or barrels?

I've already got a portable genset to run the pump.

Im sure you have already thought of this but it takes about 28,000 gallons of water to put 1" on 1 acre.
Even if your plot is tiny that is either one big water container or many, many, many times filling and emptying a smaller one.

I'm holding off this year now that rain has been coming in more steadily. I'm going to just buy a pump big enough to pump from my lake for next year.
