About powered well pumps. I have installed several types from the relatively inexpensive Sure-Flo DC solar powered pumps up to the 3-phase constant flow type. The one I really like is the multi-voltage AC/DC “SQFlex” pumps by Grundfos. These pumps run on just about anything. Solar, Grid, Generator, Inverter 30-300 VDC, 90-240 VAC 50-60 Hz and can lift water from up to 650 Ft.
@GoatHollow Great catch. You are right that the unions could go on the other side of each gate valve but in my setup I have valves on the drive pipe close to the dam that I shut off and then I take pump out with gate valve and all and on the delivery side you just lose the water in the pipe not from your source. My extra drive pipe shut off is where I can also change to a diff. drive pipe size. You'll see in pt3 . I am just glad that folks are paying attention to the details!
I first became aware of hydraulic ram pumps years ago but "got too busy" to experiment with one. Also managed to lose all the notes & articles over those years, now that I'm needing to build one for our gardening system upgrades. Thanks, because of your efforts I have hope of accomplishing the goal! You are a light in a darkening world, sir!
Right on time!!! Awesome!
The ram pump is now the answer to a HUGE task for our planned off-grid, eco-friendly, self-sufficient, and very efficient home(s) & greenhouse business! I find your videos tremendously informative and COMPLETE with all of the details and/or formula to answer all of the questions I had, I believe ;^)
You Sir are very much appreciated, thank You for caring. The World needs more like You!
Thank you for doing this series. I have seen a lot of examples of rams, but none explaining the math and how-to behind it. A+
Thanks for advising videos 1 2 and 3 with both: theory and practice.
Your series on ram pumps is comprehensive. Thanks for including the math!
I really appreciate your lessons, we are actively looking for land for off grid living, thank you! (Mr. Rain).
I have a well 220 ft down, can't wait for that video, thanks for doing these very helpful
no, questions. Excellent explanations. I really liked seeing it in action. Thank you so much on this and all of your videos.
Excellent series. I say again...Excellent series. Thank you very much for posting this video!!
tks for the upload it was really useful, have learned from it, you have done a great job.
@TheBeeperman Sounds like a Davey Ram as they are dome shaped and are great little ram pumps!
your shadow on the dry erase board shows you have angel wings...............Nice. I like your videos. spent the last two days watching them.. you r a special person.
Just love your formula.
Very usefull thanks from the mountain springs of Costa Rica.
this is a great set of equations and everything....worth a textbook
Wranglerstar built this same pump and used a 3' section of pvc 1/2 filled with a pool noodle. His lifts about 150 ft verticle roughly 500' from the pump station. Hope that helps, 3' will be the size I use when I get around to building my pump.
Absolutely awesome information you're sharing. Thanks!
Nice design. I do a lot of repair on many things and I have a suggestion for the order of your pieces. The valve should always be first and last in the sequence. This will allow you to turn off all water flow before cracking open the unions which will be much less messy whenever the unit is removed.
you, Sir, are a great dude. Thanks.
if you put the two gate valves on the drive and delivery lines rather than on the pump ie on the other side of the union you can
isolate the pump as you do now but with the advantage of being able to stop the flow down your drive line and the supply line will not drain back to where you are working. Also if you put another check valve about halfway along the supply line the pump will be far more efficient because of the reduction in back pressure. very good tutorial please keep going
It's the great invention for all people.
Bravo -----------!!!
@billythebaboon Under a $100 depending on where you can get your plumbing parts. You can save a some money by using a PVC ball valve on the deliver side. You also can leave off the pressure gauge as well. So if you shop around ~ $75 for a 1 1/4 pump 50 for a 3/4 " pump.
If you were to purchase a 1 1/4" pump from Rife Ram it would cost you around $1500.00 - I have a 2" 20 SU from Rife I bought 12 yrs ago for $900 - it is now $1950.00 !
Awesome video. Just enough so that I could do it on my own. I was sent to you by Wranglerstar
Yes a 10 HDU (10HDU Max Fall 50ft. Max elevation 500ft. Intake 3 - 10 GPM) will work . the pump cost ($1970.00). Send me a pm or got to practical preppers and contact me there for more info.
The union goes in front of the shut off valve, so the pump can be serviced, the pressure vessel dose not need any thing inside just air.
It can be
@CopingWithTheTimes It is and honor!
great video!!! keep on uploading!
very good.....waiting for part 3.......thanks
Thank you sir.. mr paras from the Philippines
First union should be after shutoff valve...that way you don't get soaked when servicing ..I'm sure someone else probably caught that in the comments..?
And last union should be before the delivery shutoff, so you don't get backflow from the delivery line.
Well, guess I do not need to ask...
thanks for video info.
👏👏👏👏love you for sharing you are the best🙏
Thank you.
"Recommended wisdom of advice"
There are several different check valves to choose from, the one you want is a swinging check valve, that way you don't have to deal with Spring adjustments it works on gravity.
@kenwilson63 You are quite welcome. Sounds like you are ready to install a ram!
thanks, waiting for when you do the well pump vids
Great work sir
Great video! I‘m planning to start this project.I‘ve seen alot of ramp pump demonstration videos but this one‘s captured my intrerest,hope to seek youy help when i started this interesting project...Good job Sir! :-)
That was great detail information provided plz also make a video on well ram pump
Awesome, thanks so much!!!!!!!!!!!!!!!!!!!!!
sooo cool. thanks
Hi, good Job ..... Outro :-D
And Thank you for sharing :-)
The Art of Ram Pumping
BRAVO!
that is soo awesome! :)
Thanks for the info. Great job! What is in your bladder tank?
GRACIAS
We live in Florida and there's not a lot of fall on my creek. Maybe 6-8' over 250-300' of creek. It has great volume though. Approximately 60 gallons per minute. Should I try a long drive pipe or short one?
Engineer 775.
Your great at the math but lacking as a plumber. Your valves and unions need to be swapped with each other. Valve first then union. Same on the other end. Then install a relief valve somewhere in the middle. Preferably right under your pressure tank to bleed pressure and drain the tank. Think about decommissioning or for the layman, disconnecting the pump from either end or both ends. With your configuration your going to get real wet and with enough pressure get hurt. You have to be able to hold back (isolate) the head pressure with a valve before loosening the union. Both the intake and the discharge are well above the pump and under pressure. Also if you use a weight adjustable vertical check valve you can then fine tune the pump for much better efficiency. Great job on explaining the math. Slow it down a bit. Take your time so that we have a bit more time to absorb what your saying.
How long do you expect this ram pump to last? Is the Brass Swing Check Valve the weak link, being the part most likely to fail? Especially since you are running unfiltered and un-purified water through it, and thus very likely to corrode?
Thank you for all you hard work and teaching. Question: will it work...if after the waste water valve you install the check valve and lay your pressure chamber down horizontally and have the delivery line feed out of the end of the pressure chamber...2" feed...5' head...1" delivery 40' elevation...
A note about the Sure-Flo, it’s a good pump for low flow but it doesn’t last. I have replaced every one I put in after about a year or three, so if you go this way make sure you have a spare or a re-build kit on hand for when it fails. Sorry I had to post this in three parts.
thanx for reply icicicle ^^ on my question (swinging check valve)
Thank you for the video!. First time watcher. quick question on your buildup. Don't you need to drill a small hole at the base of the accumulator for air intake?
Something like an artesian well which is you know a tap spring with a lot of pressure you could probably use a ram pump for but that's like a whole other ball game not digging a hole and finding something that's harvesting something that's already coming up
I think you want to AVOID closed cell foam. Worked at a factory making it. Was years ago and I hope I get this right. Closed cell uses "celogen" as a "yeast" to create encapsulated nitrogen bubbles. Closed-cell is used for drink cup holders (DCH's) and for the better pipe insulation, for wresting mats, for astroturf mats. You mentioned "noodles" ... which I *think* are "open cell." Double check, but I think this is right.
@mir09333 I haven't built mine yet, however I believe you keep pressing and releasing the check-valve to "prime" the pump, and get the water flow started. After a number of times of pressing and releasing the check-valve, my thinking (I could be wrong?) is the pump will then have the pressures in the places it needs to work on its own. Also make sure the gate valve on the outlet side is closed until the pump is working on its own...then slowly open the outlet gate valve. I hope this helps.
i have really enjoyed your ram pump videos. what is the minimum flow rate that is required to "feed" the pump? my spring feeds the pond about a gallon per minute so have about the same amount of overflow. I could use a small solar pump to increase the overflow rate.
I'm curious. Why not have a third check valve on the inlet before your hammer valve, even 10 feet back to the source, to prevent the spike from ramming back into the supply line, back to the source? Could this work, and maybe increase efficiency, or possibly prevent it from working?
Nice vdo..what is it you said to put inside pressure pump or bladder??
thnx good idea....
@DeleteMeOnline A bladder tank would work just fine and yes you can use a foot valve. You remove the spring so that is falls closed and you can also weight the valve. I have found it is simpler and easier to adjust a swing-check valve than to make your own. Weighted/adjustable valves are great and some you can make real quiet with leather or rubber gaskets.
I would put the cut off valve before the union so the water can be turned off to work on the pump!
well explained. can it be used in a river with fast moving water? (much like the colorado river for example)
do the upper check valve needs to be covered?
Hi there. Please could you let me know what is the maximum and minimum length for the drive pipe of a ram pump, the fall from my water source varies from 1 to 4 feet?
would it be more efficient to have your well pump , pump water into a tank high enough to give you your required water pressure or have it run as normal ?
My spring volume is 3.5gpm and I can get up to 30-40 of drop with the drive line to my pump site but I have to get water up 160' to the tank site and the over all distance is about 1000' from pump to tank so my question is can this work with a ram pump??? If so what pump would be recommended for this project??? Any help would be greatly appreciated.
Thanks
Justin
Can you add the pressure tank to the 3/4 in piping or does it need to be 1 1/4 in?
Engineer775, Great videos! I have a question about how you determine the volume needed for the pressure tank, and if you could, comment on the shape Hight/Diameter ratio. Muchas Gracias!!!
It is possible to construct a ram pump according to the model of a gardening hose which, on the one side, has a suction valve which has a ball that sucks the river water with a certain drop while on the other side the gadren hose is connected to a plastic PVC barrel (which can have a volume of 150 Liter) where the river water will fill the plastic PVC barrel or that the drain valve can be made on the plastic lid or hood ?
Should the unions be on the other side of the valves so you can shut off the drive pipe and delivery pipes and take the pump out without having to drain the water from those lines?
Единственный чувак во всем интернете, который суперпонятно показывает как сделать вечняк. аплодисменты
Sir you are saving me money--thank you!
What length is the schedule 40 you cut for the pressure vessel and does it matter?
I wonder if you could show how you use that foam inside the pressure vessel? Thanks for sharing.
Hey, can you please send me the schematic for the pump? I can't understand the set up for the valves. Which direction they are flowing in and shutting. Kinda lost with the arrows you say.
What size of pipes do i use if i need to bring the water from a river up 100 meters?
Do you bolt your ramp pumps down? When your putting it together on the table you just spin your delivery hose on but outside i would imagine both your delivery and source pipes would be held fairly static or at least be very long?
Is that where the unions come in? How do these allow you to disconnect the ramp pump?
I do not recommend the Grundfos CU200 control box, I have installed two of these and had to send two back for warranty. I do recommend the Grundfos IO101 control for solar powered systems; this box allows you to automatically switch to AC power, (generator or grid).
Would be nice to show a diagram of the pump and show how it actually works. Much like you did with flow rates and drops in elevation. It's great you put one together but how does the water flow through it and build pressure?
yo..buddy... does it good if i put another check valve on the delivery pipe(that is in between the pressure chamber and gauge as per your model in this video) ? nice demonstration indeed! thanks!
is it okay to use empty gallon as pressure vessel?
is there any specific size for the air tank?
I've built it with PVC. The line from the source to the pump is 2.5'' (6 meters length) ,the line from the pump to my storage is 1 1/4'' (25 meters length) and my air tube is a 19 liter hard plastic bottle . The system is completed but I have a problem. When I let water go, water go up and the bronze check valve is closed and the air tube is filled with some water. But that's it. It doesn't work automatically even if I push the valve. Also there are little leakages in some links and the spring valve but I can see enough pressure at the bronze check valve and my gauge (about 0.3 bar). Do these leakages cause it? or what's wrong with my system Sir?
Inlet: for maintenance, the valve should be first, then the Union.
was there a reason you went with the longer nipple on the clack valve?
Very interesting. I remember being at an antique steam engine and farm machinery show and they had on display something like this, Only it was a dome shaped contraption. If i remember right it was called a Bell pump. They said they were using them back maybe 200-300 years ago. Could they be using the same principle?
I like absolutely your ram pump. i ask one question sir about pressure vessel what is the component inside. and how its made.and thanks engineer775.
Do you use just swing check valves for both your waste and pressure valves? It sounded like they both clapped freely, so I'm assuming you are using check valves on both. On the Clemson Extension link you gave, they show the pressure valve as a spring check valve. What would be the advantages/disadvantages of using either type, for your pressure valve?
What is the difference with a snifter and without? Which is better?
Good job! I wanna build my own pls help me.Are these materials available in the market without modifying them specially the valves?how much it all cost?
is it 2 1/4" x 3/4 " bushing?
I havent seen any discussion of how to determine the size of the Pressure Vessel.
Ive got a 10 ft drop to wherr i can set pump an need to send up elevation about 50 ft 300 ft till lake final point. Im makin a 1 1 1 1/4 "to 3/4 outlet what does my pressue chamber be. In height. An do i need a water chamber before .my drive pipe.last 50ft is a 5 ft drop.
it was good projact
For compression then pressure I believe.
Are the two check valves really have the same specs? i'm confused because i checked the material list and found the same but got diffirent function...pls reply.
i use it for paydirt cleanout
