3 Ways to Find Ram Pump Lift Height

The ram pump needs input head pressure to opearate. For every 1 foot of water falling into the pump you can expect to get 7 feet of lift up from the delivery pipe. But how do you measure the lift height from the pump to the top of your hill? In this video I show you 3 ways to find the lift height. There are other ways to find this value but these 3 are a good place to start.

I like the way you capture and explain your mistakes, noticed that on a few of the videos. It’s good to see the authenticity.

[DragonUdo]

That is some really great info! I'm glad that you thought of doing something like this because some of us might be ignorant to this type of thinking.

[patrickhoffmann]

Nice, I like this more accurate/scientific approach. Haven't you done this already a long time ago with your brother-in-law? And probably the first time you showed a formula on Land to House!?? Btw., if you account for the 1.5 feet your head was above the ground when using the goniometer/protractor, then the values for the last two methods are quite equal!

[benjaminwatkins]

thank you for helpful and simple ways a non engineer can make the ram pump successful. great job!

[MStrickkk]

These were so much more simple than the ideas I had to find distance

[keithsexton]

Yeah use that before this helped all trees are around my house and it works.

Great video! If you don't have strings or long tapes, you could use that protractor + straw method and using a barometer/altimeter app (most phones have this) can measure its change in Z axis (height) with relative accuracy. So using the same formula, but plug in the height value and solve for hypotenuse to get triangular distance between the two points.

You can also use laser range finder for hunting

Great video, very informative!

Although the efficiency of homemade pumps does show here! 1:7 fall to lift ratio whereas the papa pump can achieve over 1:30

[keithsexton]

I have used that method to to find out the degree of slope in my driveway.

[REMRETS]

I would really like to see more of the rampum powered generator

[jllaine]

Neat exploration, thank you for that. The water filled pipe and pressure gauge might be more useful for folks actually installing a ram pump, since the delivery pipe has to be run anyway.
BTW next time you run a camera down a mine shaft, use that long long tape measure instead of string and it will spin a whole lot less.

A short cut on Method #3. When you have multiple steps to get the elevation change, you can measure the distance from the ground to your eyes once (say if you are 6 ft tall, your eye level is about 65 inches.) Then, on each step down the hill run the line out to where it shows level right at your eye level. Then only on the last step will you actually have to make a tape measurement. <bb

Great examples. I like the .433 method. :-).

Thanks for taking time to explain how you determine your difference in elevation. Never seen the straw thing before. Just wanted to say you’re using the terminology wrong when describing pump performance, specifically lift. . Lift is actually how high a pump can pull water on the suction side, not how high it can push it. A ram pump cannot develop suction lift, the water level has to be higher than the pump for it to work this is called suction head when water lever is higher than the pump. Discharge head is used to describe how far a pump can vertically push a liquid. The height of the water on the suction side has to be subtracted from the head on the discharge side. (Total head = Discharge head-suction head ) for example. If you have a ram pump installation where the discharge head tops at 100 feet above the pump. The source of water is 10 feet above the pump suction, the total head for the pump would be 90 feet. Say the suction line is in a pool of water in the creek and summer drought lowers it to 5 feet. The pump discharge head would be also be reduced 5 feet so you could only push water to 95 feet. Not a big deal if the pump has plenty of discharge head for the application. When someone is pushing the limits of a pump they may find themselves out of water if the source starts to dries up.

[keithsexton]

Don't forget to add the distance between your eye and the ground is a factor too.

[SkilletintheWoods]

Great video! Thanks for explaining how to do this.

[davidgroff]

There's a elevation app i use to measure elevations on my phone

[hayderalsalman]

Great Job...I need to ask what the ratio between water out from Waste valve to water flows to discharge of ram pump?

[ImbaCore]

What about using GPS data? Could You compare to basic cellphone gps app with this video?
