How far will a irrigation pump pull water before it gets to the pump. I need to pull water about 60ft to 70ft up hill before it gets to the pump. Will it work

There are pumps that are designed to pull water up 100's of feet. It all depends on what kind of pump it is, and the demands of the system.

So a 1.5 hp pump from lowes will not work

No it will not.

Sure it can, depends on static head.

It's easier to push water than to pull it...most pumps will pull about 25' max (especially irrigation pumps from lowes). Right now I'm pushing about 50' - 60' vert and about 350 total length through 1.25 pipe...and running a boaster at the top of the hill. The pump at the creek is 4 hp and although it will push 150 gpm, frictional and head losses are so great that I need a booster. I have plenty of water with just one pump but I lack pressure to irrigate, hench the second pump.

It's best if you locate pump closer to the water source if you can. If you can't do this you may consider using a jet pump. For me wire cost is prohibitive so I am using a gas pump at creek. At the cost per 1000 gallon of water here I am still saving.

Not even a chance with this pump.

It is physically impossible to lift still water as much as 35 feet in a suction line, because the water will begin to vaporize in the vacuum conditions in the suction line. If you have to have the pump 70 feet above the water level, you can use a more expensive convertible jet pump, with two pipes running into the necessary ejector assembly in the water. The amount of water you get with this kind of arrangement will less than with any other pump, because a good deal of the pump effort is in pushing water from the pump to the ejector assembly far below it.

I have plenty of 1.5 POC pumps pulling water 100 - 150 ft from the source. Question is how much lift. Here I got about 5-10 ft lift from the lake or canal and 100+ to the pump. Check valve @ the source, once primed, not a problem.

His problem is the 60-70' elevation lift, not the distance to the pump.

He might have a run of 60-70 feet up an undetermined slope, and can maybe have 20 feet or less of actual suction lift. 20 feet of lift is about as much as I'd want to see in a design, and of course the suction pipe diameter has to be bumped up a size or two, so that it has almost zero friction loss.

Your lowes pump should contain a paper which has pump curves...that should tell ypu all you need to know.

That's not what he said:

He didn't say 60-70' of lift, he said 60-70' to the pump.

1.5 hp will lift 25ft & vertical & 100ft horizontal. I'm with Boots though; 20ft of suction lift through a 2" pipe is a comfortable design parameter.

We dont know if he's talking vertical or horizontal.

Right, so to tell him 1.5hp from Lowes won't work is stupid.

If the op read my reply he would have all the info he needs.
