Ram Pump Height vs Flow Chart Building

The ram pump is a water pump capable of lifting water to a ratio of 7 feet for every 1 foot of input head pressure. In this video I test out how much water flow there is at a few lift heights. I am using the 1/2" ram pump in this example.

I really am enjoying your videos on ram pumps. It seems like it would be perfect for irrigating a garden up a small hill. Thanks!

You've come a long way in a short period of time.

I noticed that, on your first test, the hose was dripping outside the edge of the container, making your first reading slightly less than it should have been. This could be why the second test was almost the same as the first one.

If you put a clear short hose on your non-running ram pump (maybe where the pressure gauge goes) you can hold the end up and see how high the water goes in the hose --- that will be level with the top surface of the water in your source bucket and you can measure from that to the ground to get the exact head height.

thanks, was just wanting to watch exactly this type of video♡♧♡

Ive been doing testing with a 1/4 in. Line ram pump i made and i came up with a intresting addition to it you or others might be intrestid in .
I hooked up a bicycle pump to the first check valve to quick charge the pressure for a instant start up and it worked on my first test, gonna redesign that it into this build i have by adding 2 more check valves on other sides of output and pressure tank with 1 of the valves for the hand pump inlet and see if its a practical addition or not .

quick question, could you make a staircase of ram pumps (for every foot of head pressure you get 7 feet out) what i am asking is, on a hill every 5 feet down there is a bucket with a 1 foot drop supply pipe to a ram pump that feeds the next bucket up the hill, do this for a few "steps"?

[CraigTaylor]

Is there an optimum air pressure inside the pressure tank? Have you ever put a pressure gauge on that? Would supplying some compressed air help?

[BeezyKing]

quite interesting to see that drive pipe length and diameter affects your lift height

[farmerjim-fat-man-do]

Good demonstration of the ram pump lift ability. Question regarding the measured heights mentioned in the video. Are the 20’, 25’ and 32’ test points measured from the pump or the bucket? If measured from the pump you will need to subtract the head height between the bucket and the pump. If measured from pump the actual 20’ measurement would be 14.5’.

Hi Sam, so far so good .
I appreciate your hard work 👍❤ and I am so wonder what happen if you add a small electric or solar pump to the system

[railroaded]

Was wondering if one could use multiple ram pumps to pump an amount of water up higher than with one. In other words you have a large one initially. Then up higher you utilize the water delivered by the big pump to run a smaller pump. OR multiple pumps at each elevation. ????

[steve-o]

People spend a lot of effort matching the ram pump diameter to the drive pipe diameter but not to the delivery pipe/hose diameter. For instance, they will have a 1 inch drive pipe and ram pump but a 1/2 inch or 5/8 inch delivery hose. I would think any delivery pipe/hose diameter that is not matched to the ram pump diameter would have a decreased amount of water delivered. Maybe people could get substantial water throughput improvement just by using a correctly sized delivery pipe/hose. Perhaps you could test that on one of your very informative videos with a 1 inch ram pump and various sizes of delivery pipes??? BTW, really enjoy your RP videos!

Does 1:7 ratio stays the same if you increase the input and output pipes' diameter?

[petersboro]

Have you done a video how your pump could be modified to do better than 1:7? Would a steel drive pipe help? Would a shorter drive pipe with the same rise have less friction thus more efficiency?

[misterdubity]

You could attach the outflow part of the hose to a long pole or a 1"x2" or something to lift it higher. It could be extensible like an extension ladder. I have one for changing ceiling light bulbs. Or you could raise your RAM pump up on a box to decrease the head pressure from 65" to 60", 55", 50" etc That way you could get several ratios for the same location of water source and outflow hose. But at some point you'd get below minimum head pressure needed. Or rope over a high tree branch, tie rope to outflow raise until output just barely stops = maximum output pressure

[steve-o]

Probably the easiest way to get the head height and the delivery pipe height is to 1) make sure both pipes/hoses are full, 2) stop pump, 3) measure psi on the high pressure and low pressure sides of the ram pump --- divide the psi on each side by .433, each foot of height generates .433 psi (ie. 3psi / .433 = 6.9 feet of head height, 20psi / .433 = 46.2 feet delivery height). No measuring hoses or laser levels.

Wow hey brotha, just found your channel
Looks great i have seen some videos from others, your details are very interesting, just wanted to mention using a garden hose while going uphill, do you think a solid pipe may hold the pressure better ? You got me hooked

[CyberviewU]

I wonder if using a 40-60 ft. length of tubing for a drive pipe in a switchback pattern over the 20 feet of run would increase head pressure. It would always have to be descending to avoid slowing the flow and the extra weight might provide more pressure in the drive pipe. It should join a few feet of hard pipe before the pump. Would it increase the length of the drive pipe without affecting the amount of fall?

[Emulation_Inflation]

Could you hook another ram pump up to the discharge on the flap valve? Like have that setup you just did and the add/run a ram pump with the wasted water that just runs on the ground?
