Which pump for a long horizontal run?

[kpalas]

Hello, I'm in the process of planning my saltwater mixing station, which will be located in my garage.I want to be able to push the water approx. 70 horizontal feet, then maybe up approx. 6 vertical feet to the tank, which will be in my office. Can anyone recommend a external pump that can handle that? All the ratings seem to be in vertical head pressure, so I'm not sure how to convert it. Thank you!

You can use a pump head calculator like this.

You need to know approximately how much flow you want to start. So let’s just say you want 5 gallons a minute (300 ghp). Assume five 90’s and 3/4” pipes, plus the 70 feet and 6 feet you gave. Then the calculator gives a total head of 10 feet.

This means you’d need a pump rated for 300 gph at 10 foot head.

Because pumps are rated max flow @0 feet head, or max head at 0 flow, you have to use a curve like this one. It shows 792gph but only at zero feet head. Or you get ZERO flow at 13 feet head. So obviously that pump won’t work.

Here’s a pump the could work for the assumptions above. If you want a specific pump recommendation we need to know a little more info from you.

Ok thank you. All I'm looking at doing is to refill the tank after a water change so it doesn't need to be crazy fast, but I don't want its to take all day either. I appreciate the info.

Any of the medium sized pressure rated panworld pumps would work - 40PX or 50PX.

Ok thank you.
