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!
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.
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.
@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!
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.
Your series on ram pumps is comprehensive. Thanks for including the math!
It's the great invention for all people.
Bravo -----------!!!
no, questions. Excellent explanations. I really liked seeing it in action. Thank you so much on this and all of your videos.
I have a well 220 ft down, can't wait for that video, thanks for doing these very helpful
Excellent series. I say again...Excellent series. Thank you very much for posting this video!!
I really appreciate your lessons, we are actively looking for land for off grid living, thank you! (Mr. Rain).
tks for the upload it was really useful, have learned from it, you have done a great job.
Just love your formula.
@TheBeeperman Sounds like a Davey Ram as they are dome shaped and are great little ram pumps!
you, Sir, are a great dude. Thanks.
The Art of Ram Pumping
Very usefull thanks from the mountain springs of Costa Rica.
Absolutely awesome information you're sharing. Thanks!
this is a great set of equations and everything....worth a textbook
very good.....waiting for part 3.......thanks
Thank you sir.. mr paras from the Philippines
thanks for video info.
great video!!! keep on uploading!
Great work sir
Awesome video. Just enough so that I could do it on my own. I was sent to you by Wranglerstar
👏👏👏👏love you for sharing you are the best🙏
That was great detail information provided plz also make a video on well ram pump
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.
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.
Thank you.
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! :-)
thanks, waiting for when you do the well pump vids
sooo cool. thanks
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.
Awesome, thanks so much!!!!!!!!!!!!!!!!!!!!!
Thanks for the info. Great job! What is in your bladder tank?
Hi, good Job ..... Outro :-D
And Thank you for sharing :-)
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!!!
thanx for reply icicicle ^^ on my question (swinging check valve)
thnx good idea....
that is soo awesome! :)
@kenwilson63 You are quite welcome. Sounds like you are ready to install a ram!
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!
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...
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
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
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.
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
Nice vdo..what is it you said to put inside pressure pump or bladder??
I wonder if you could show how you use that foam inside the pressure vessel? Thanks for sharing.
"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.
Sir you are saving me money--thank you!
What length is the schedule 40 you cut for the pressure vessel and does it matter?
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?
well explained. can it be used in a river with fast moving water? (much like the colorado river for example)
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 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?
it was good projact
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?
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.
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?
BRAVO!
@CopingWithTheTimes It is and honor!
GRACIAS
Can you add the pressure tank to the 3/4 in piping or does it need to be 1 1/4 in?
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...
@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 !
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?
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?
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?
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?
@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.
do the upper check valve needs to be covered?
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?
Does the length of the pressure vessel make a difference?
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.
Hi. Given the current times I am putting in a Ram Pump. I am using your design in this video. Question when installing the waste check valve is there a optimal orientation for the valve in its 360 rotation. Specifically the access cap on the valve. In the video it is oriented at a 90 degree angle to the linear flow of the water. Is there a benefit to pointing it Upstream or downstream of the flow? I saw the demonstration of changing the perpendicular angle from vertical and understand the volume adjustment but it I didn’t see this other point in your video.
Another hydraulic question. Is there any benefit in a high flow creek ram pump set up to start out at the filter input with a larger pipe size say 4” and drop that down to a 2” for the drive pipe. Would this increase the velocity of the water before it hits the ram increasing pump potential? I have a bunch of pipe around.
I am putting in a 2” Ram
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 ?
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.
what is the pcv pipe for and what if u change the lengths and widths
What is the difference with a snifter and without? Which is better?
I havent seen any discussion of how to determine the size of the Pressure Vessel.
Hello, Why do you put foam inside the tube please? Is it necessary? Thanks!
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
What if you created a vacuum to pull from a well then run a ram for pressure?
hi, my question is when you use a tire tube in the bladder. how do fit it in and get the correct firmness of the tube? can you actually show a vid of you assembling the bladder itself.?
Nice. about pressure vessel there are component, inside sir? how its made.
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?
Sir,I saw a piece on U Tube about making a piston with a spring in place of the blatter assemble. ,what are your directions and comments.
Is that everything needed in the list at end of video
Hi nice vid. I got a question. The first check valve you install, minute 3:36, i bought the same one but when the water flows and hit that check valve the pressure its just to much and doesn't permit the valve to stop. This mean my ram pump still not work. Could you please explain to me what should i do thanks a lot.
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 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 ?
was there a reason you went with the longer nipple on the clack valve?
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.
Great job Dude. One question, wouldn't it be better to put the unions "Inside" of the gate valves, so that you can remove the pump, and have no water flow from the inlet/outlet pipes while you are working on it. Seems like it would be lot's better to be able to fit those unions back together with no flow/pressure coming out of the other half of the union. Btw. hope you don't mind, I'm downloading this series, to burn to DVD for after SHTF reference.
I watched your Part 1 and have 2 questions. One is when the flow is low , say 2.0 - 2.5 gpm the largest intake line can only be a 1/2 inch pipe. Schedule 40 PVC preferred. I believe the average maximum lift is a 1:7 ratio with a top lift of no more than 170 vertical feet. Therefore to maximize a systems potential , the head ( fall ) needs to be approx. 24 feet to lift 170’. I like this however your formula does not support this type of system . Number one you state the delivery pipe needs to be half the diameter of the supply line, so for a 1/2 pipe, this would be 1/4” which is not standard for this use in poly rolled pipe. Secondly you state that for head of approx. 24’, the length of the supply line needs to be 4 x the fall or approx 100 ‘. My question here is : Can this length be shorter or longer by some established percentage or is it critical to your formula?
For my use, I have a minimum flow of 2.0 gpm. I need to lift it to a minimum 500 gallon tank . This tank sits 160 feet above the discharge point of the ram pump. This because I need a minimum of 35 PSI to my points of use and that is why the storage tank is set as high as possible on the farm.
I have been told that most RP’s discharge 80% of the water back into the spring fed creek. So I get 20% of the water coming in or .40 gpm. Or 1440 x.40= 576 gallons per day. This is great except for your 2 points regarding the sizing of the intake PVC line and the output lift line. I would love to hear your thoughts on my comments.
Thanks, Michael
Can you plz list every pieces we need?
