We made a new model of rampump that is suitable for absolute noobs. Minimum of parts, simple build! We had some problems, it looked like a big rampump fail but at the end we managed to pump more than 2 liters per minute anyway.

The best ram pump ever. Always doing these projects intelligently, obtaining great results. Congratulations.
This seems like the perfect solution for me as I never seem to get time to build your other valve design. It's small portable and built from off the shelf parts. Brilliant Bohumir, just what I need in time for summer and my vegetable garden.
A very much simple design but effectively works better than those complicated one. Thank you, will make this too.
Brilliant work Bohumir! It looks more efficient than many other ram pumps I have seen.
The first video I have seen on TH-cam that did not get a dislike....a Great video Bohemir. I have a ton of question.
I had to give a thumbs up because of the "pure magic." :-)
THANK YOU BRO FOR EXPLANATION AND SUCH VIDEO , ALL RESPECT !!!👍🙏
thanks bro
greetings from the philippines
I really like your new check valve! I am doing one this week.
Wow!!! Brilliant!!! This is the best ram pump👑👑👑
Congratulations! Job well done.
Good video, great job. Ty.
Thanks a lot. very interesting.
Great video series! It looks like a lot of people including me is finding it hard to find the 1" blue plastic "ball" valve. The foot valve that you compared in your "flap valve bad" video is easily found here in the West and seemed to do a good job and would just need the interior spring removed. Did you try that one here? And if the 1.25 inch one you showed previously was too big perhaps a 1 inch one would function well and still be good for a noob.
Really great idea . we have a dry creek that occasionally fills and runs massive . be ideal to fill for storage tank for summer heat
Have you try to troubleshooting again your previous ram pump by changing the rubber ring inside to a metal like stainless. That will make the pump work faster.
Interesting results! The ram pump is based on the inertia of moving water - therefore, you need to have the highest flow possible when the waste valve is closed, and it must close as fast as possible, to get the highest pressure spike. I still think this valve is not as effective as your custom design, but I admit I was surprised with the results!
I also think that the rubberized metal ball that forms the seal in this valve will wear much faster than your custom leather seal, particularly because it's sealing against a metal lip. This video is almost one year old, so I guess you will know more about this by now :-)
Actually, not so bad with the wear. Because we have brushed and polished the metal lip... The ball looks still good.
I'm a bit lost about the details of this pump and the parts i need to buy compared to your more detailed previous versions (with different valve system). Can you give a bit more details about this one ? Thank you !
That looks like a great idea for many reasons. It seems much quieter than the other metallic valves, I would assume the ball rotates and spreads wear all around the outside of the ball.
Do you have any information about how long it lasts before needing service or replacement?
Hello, thanks. Yea, that was also my question about the wear. It ran for about a month in a row. Then my father checked it and said that there's no wear on the ball at all. But time will show more...
Congratulation to you, it is a good project how abaut if you put biger tank is ther any diference with the small tank
Bigger tank has longer lasting pressure. You get steadier stream. But it takes way longer time to prime it. So this is a good compromise.
carrying on your fathers great thinking .. Two heads are better than one .. congratulations . I saw a small bleed hole in one design what is the idea behind the bleed hole .. .
It is a sniff valve. You need it if you don't use the bladder tank. The air disappears from the tank over time...
In my country the pumps are nothing. Now I am trying to understand and to do testing.And we will distributed. Your supporting is helpful for us. We will like to purchase if we can not make in here.ok
Please i have a question; using a basic Pressure is force per unit area.
If we use a ball that is twice as heavy has the current one you have, will it double the pressure?
Please advice. Thanks.
Excellent configuration 👀 .
I am running one at a summer place in Maine .
I'll check out your videos and subscribe 👌
I don't get it, how do you get such high pressure from the low-pressure side of the RAM PUMP? Can you describe the principle of your achievement?
Could you explain a bit more about this specific pump and how the ball acts inside the valve ? Also i don't see a second valve, i thought there needed to be two valves for the pump to work?
Yes, there's this blue valve and there's a 3/4 valve that is placed horizontally. The ball acts as a valve. It stops the water flow at the upper position.
Where can I find that style of waste valve?
Hi I have built a ram pump connected to a fish tank to recycle the water, using your waste valve design. The waste valve however does not close when opened. The length of the drive pipe is 3.8m to the pump and its diameter is 1" same as the pump diameter, but a 2" waste valve. The water head is about 1' above the pump.There are two elbows, one under the tank, and the second about 1.5' from the first, but not part of the 3.8m drive pipe. What might be the problem?
It looks like that valve also self starts. Is that so?
A very useful video... What do you think would happen if you were to use a larger size waste valve e.g. 2". The ball would be heavier and more water could pass through. Would performance improve?
for is this is the biggest size possible. For bigger valve one needs more initial water pressure. So, it depends.. If one has more pressure, then it would help...
@@BohumirStehlik Thank you. Im not sure if you have any ideas, the ram pump i have built has 2 oddities. 1. The water comes out of the delivery pipe in pulses rather than a flow 2. The delivery pipe needs to be at least 7m above the pump to generate sufficient back pressure for the pump to operate. The head is only 1.5M.
Any ideas what could be causing this? Im stuck!
@@davidstroup974 thank you david
This looks very interesting, Bohumir, and I'd like to have a go at building one. However, I think that check valve will be difficult to find. I've looked online at various sources but I can't see one anywhere. Where did you get yours?

@@BohumirStehlik Many thanks. I must check if they ship to the UK, or try and find a supplier here.
I sent an email to them, Bohumir, to see if they ship to the UK. I didn't get a reply, probably didn't understand me, so could you ask them via email if they do - and what the cost would be? I would probably need two initially.

What is the name of this manufactured valve (blue one with ball) that you use here? Where can you purchase it?
It is a suction basket with check valve. Available in a pump shop.
Hello Bohumir,
I am very interested to learn about ramp pumps. Your videos are very good and I’ve learned a lot.
I have a question. What is the minimum intake pressure needed for the ramp pump to work? If my site does not have the drop in elevation, how long do I need the intake pipe to be to create the necessary pressure?
Appreciate your help.
Thank you in advance.
Hello, you need a certain downfall. I would say that actually the maximum lenght for this size of the pump is the 50 meters. I am preparing another video where you will see that we have now actually intake to the intake. You can use it to have the water level higher. Last week I was working with downfall about 1,5m, it was slower but it worked fine.
@@BohumirStehlik Would you say that this "blue" valve is better than your homemade one on this size of pump ?
@@m1m1thecat Each of them is suitable for different type of people. If you are a pro, take the custom homemade one. That one can run anywhere and make maximum of power. The blueone is for noobs. It is better than the swing check valve but when the water flow is too low it won't work.
@@BohumirStehlik Thank you for your answer ! It's all clear for me now :)
Very funny 🤣 good video...
Where can i get a ball valve
Yes,i thing excellent.
In the USA they are called foot valves
im wondering if this will work on 1,500mtrs distance from the water source?
I think so...
Does the intake pipe have to be so long? I would like to make such a rampump but the stream that I have in my yard is only 2-3 meters long, then it falls straight into a lake. Do you think it would be long enough to create some pressure?
Maybe some pressure but not enough for running and pumping. Or you need to have a REALLY small pump.
@@BohumirStehlik Thank you for your ultra quick reply ;)
Depends on how much fall you have. If you have 6 ft or 2 meters of fall but a very short intake pipe length you need to go to a large intake pipe. 4 to 6 inches in diameter, it's all about the weight of the water and fall. If you have a 1.5 inch x 150 ft intake pipe let's say it holds 25 gallons. If you have a 4 inch x 25 ft it might hold nearly the same amount of water. Inertia is inertia, we use 3 inch diameter irrigation lines on our alfalfa fields. We can run 25 impact sprinklers at a time. If we used a 1.5 inch pipe with the same water pressure we could only run 5 sprinklers. You will just have to experiment. Good luck!
Would this work with a 1/2" width system?
Additionally , would this orientation work with the previous pump design? An in line is more convenient as you mentioned
i can't find this valve in Germany. please share link to buy this blue check valve
BlackEagle 1903 It’s a suction basket for a well. Otherwise normally installed at the bottom of the suction pipe in wells.
I had no success with the company listed by Bohumir - they didn't reply to my emails. However, I have now found one on Ebay, which I've ordered - tinyurl.com/y5tmbohs
For less pressure loss and maximizing use energy of water shock (hammer effect), can You try to install the tank horizontally?
Meaning In direct way of water stream stroke in “T-part” ...
Bladder tank maybe can handle it?
I don't think so that it would have any effect on efficiency to place the tank horizontally. And I am not going to use this type of setup anymore. It is quite stupid to have the valve in the middle. All of the scrap and mess from the water goes to the main valve instead of the waste valve.
@@BohumirStehlik Understand. Dirty water, mud and sand was an issue in our installation.
Same setup - small vertical drop and long PE pipe as a solutions for this condition.
After many tries and tweaks we found as best solution this:
100+ liters plastic barrel near to pump
Positioned and leveled up to input water level (Communicating vessels principle en.wikipedia.org/wiki/Communicating_vessels )
On top (or quite lower then top water level) connected to pump with straight solid iron pipe (that's important), min 2" diameter
Pump input iron pipe length depends on waste valve frequency and closing speed (The absolute water shock with the highest pressure only lasts until the pressure wave runs from the waste valve to the beginning of the pipe and back to the waste valve. The wave propagates at the speed of sound.)
Intake from PE pipe connect in bottom of barrel. Optimally in side position to make vortex with cylindrical filtering effect
Bottom barrel central waste valve for discharging settled sand and mud. Use as big as you can, a short but strong current will do the best job ... ;-)
@@BohumirStehlik So what will you be using? Updating video to reflect?
is there another name for that waste valve im having a hard time finding one in Philippines
Spring Check Valve.
I dont see that valve in Poland. That company send for Poland? That Webside all in Czeski, i cant see informaction for send... could you help me?
Try to contact them or find a similar one in Poland. I am sure there are many almost identical valves.
It is better to use your customizer waste valve, my friend make a waste valve almost the same you lade, but he use a tyre rubber instead of leather. I made also a waste valve almost the same theory as yours, but I used a heavy equipment tyre more tha an inch thick. Very durable and long lasting, till now not encounter any problem with my waste valve.
Can you make a ram pump that start by itself
If you stop your ram pump while it still in operation, can it start by itself?
No, not possible.
Good day, I am Denis can you demonstrate step by step how to assemble ram pumped, it's our pleasure if you can.
Check my other rampump videos..
Sir may check valve does not work why?
As a biginer pls explain step x step how to make a ram pump, and it's operation, because I want too also to make myself for my use .
Hello. You can watch my playlist where I sgow how to make the pumo and also how to make my own custom waste valve. th-cam.com/play/PLtuLfNASMMwG58-nCwZxlEJukC1E0ZABu.html
What is the size of the pressure tank
This one is I think 3l or 5l.
Bohumir, can you explain a bit more on the position of the bladder tank? With the custom made waste valve you built earlier using the Galvanized Tee, the tank is after the waste valve. And also, what do you mean by bladder tank? Do you put a tyre tube inside the tank?
Tire tube or I use an expansion tank. The bladder tank here is after the valve. Actually, it has some pros and cons. Pro is that the pump is super compact. Con is that the pump is sensitive about quality of water.
@@BohumirStehlik Thank you. I meant to say, on the other setup with customized waste valve, the tank is before the valve. Anyway, appreciate it.
Bohumir do you have a list of the items and size you used to build your ram pump?
Thank you. Somewhere in my videos is a video step-by-step. It is incl. my custom waste valve. But it is really easy to make it yourself. Just visit a plumber's shop.
@@BohumirStehlik thank you Bohumir where I live in Jamaica. The valve you mentioned is not sold here. What is the size of your bladder tank? 20 Litres?
@@BohumirStehlikthe 3/4 inch valve - what type of valve is it?
@@DOW876 8 litres.

Has anyone found a supplier for these valves in the UK, or from someone who would ship to the UK? I have tried to contact the company in Slovakia that was given by Bohumia but have not had a reply.
Something like this ? www.amazon.co.uk/Strainer-Plastic-Filter-Return-Diameter/dp/B087J9MCFW?th=1
Hi. I would like to know how many L/s in drive pipe before not install ram pump.
For 1" it is enough to have approx 6l/min.
@@BohumirStehlik . So is it enough or not water capacity from water source when ram pump rum at 24 hrs?
@@aungmyokhaing6795 How enough? I don't understand your question because you don't write what is enough. The pump needs approx 6l/min. Anything above is ok.
@@BohumirStehlik I mean that you collect water from flexible pipe by black color tank for drive pipe. "I want to know flow rate of water from flexible pipe". Because flow rate is low than drive pipe, ram pump can run only when water level from black tank is full or higher. So ram pump can not run for 24 hrs if flow rate of flexible is low.
@@aungmyokhaing6795 The flow from the red flexible hose is much higher than the pump needs. Thr water travels freely in the red hose but in the black drive pipe the water goes only step by step thanks as the pump works.
Can I avail your ram pump?how I'from philippines.
Your original pump was pushing 5000L per day, this pump does 2*60*24 = 2880 L per day.. how do you then come to the conclusion that it is "almost the same" ???
You missed the part he mentions different pipe size due to less water in the stream this year..
Hi, I am just intrigued as to how to connected the pressure gauge to the t-piece. Could you enlighten me please? Thanks
There's a thread...
Heart bit pump
You didn’t mention the difference in elevation from your ram pump to the top of the hill where you measured 2 liters in a minute as well as a pressure check. That is one of the most important aspects of your test.
Probably in other videos. Intake downfall 2,8m, delivery height around 17m.
Parts list
Check other videos. Thx
One year latter
your previous check valve was much better I think. You can adjust it easily. Not this one.
You are right. But not everybody can make it. That's why there is this simple valve.m - still much better than a standard swing valve.
