2 Stage Ram Pump

- This is a culmination of my 2" ram pump model that I will offering for sale www.ebay.com/i...
I sell other sizes too in kit form: www.ebay.com/i...
The theory is that the big ram pump makes the small ram pump behave like it's operating at much greater head heights. In this case the big pump magnifies the head height from about 6ft to 46ft. The secondary pump then amplifies 46ft to about92ft. Much tuning would be involved in just the second stage setup to get it to operate at higher ratios. As you see they are only operating at 7.6:1 (primary) and about 2:1 (secondary) ratios or about 15:1 overall.
My 2" pump while operating at 3ft head heights can achieve 20:1 all on it's own, I suspect the 2" pump with the adjustable waste valve I'm STILL working on will operate the primary pump at even greater ratios at the shown 6ft head height.

Living in the city, I so wish I lived near a public water source, just so I could make a device like this. Its really cool
The really cool part is - that he can use his booster pumps as sprinklers. Irrigate endlessly up hill.
It certainly looks like the pump works on the inertia of the oscillating water flow, you could use a rotary valve to achieve the same pulsating effect but that would be more complicated, fascinating things
I also only had 3/4 inch pipe going into the 1/2 pump. Surely that's a factor.
It would be more complex but you would gain the energy from the water that would normally be lost via the waste valves.
When Seth did his vertical drive pipe test he only had 10ft head (4.33psi) and 1/2" pipe for 60psi.. Your 2" pump is delivering 20psi (46ft head) so i guess the flow rate is the limiting factor. If Seth`s 10ft head managed 60psi, you`d expect a 46ft head to do a lot more than 40psi.
Can you measure output on the second pump so we can consider the investment into the second pump, but the pressure doubled based on video. May to show the before and after
Neat experiment!
You can achive even higher preassure just by fixing the pumps firmly to the ground. Exelent experiment!
Good tip. 🤦♂️ now that you’ve said it, it’s so obvious, but I’d actually never considered that. Thank you!
That's rad.
I need a pump to lift 65-70 feet. Seth said it's not doable. What do you think?
What is your input height?
@JoeMalovich I can make it just about whatever. I can build a dam.
@@TheAwesomeHomestead I have not extensively tested this setup, I suspect it might but it would be difficult to find the right configuration. Even if you managed to get 3ft of input height, the output flow might be low.
It seems like you might have plenty of flow, have you considered a waterwheel spiral pump?
@JoeMalovich the property I'm damming isn't mine. I was told I can damn it for a ram pump but nothing more
Does the second pump need to be below the 1st or can you use it as a booster a little ways from the max hight of the primary pump?
I'm not entirely certain but intuition suggests the best spot for the secondary stage is below the primary stage some optimal distance of pipe away, probably between 20ft and 60ft.
here's the problem, folks. a ram pump can ONLY lift an amount of water equal to TEN percent of the source flow. this fact should tell you that, using two pumps in line moves One ONE-HUNDREDTH of the original source flow.!
Good point. So if you've got a lot of water at a low head it could work if your first stage is big enough and your required output isn't that big.
Actually, Ram pumps can pump up to 30 percent of the flow they are supplied, see our Papa pumps as an example, a supply flow of 60l/m and can pump around 25,000 l/day :)
@@Waterpoweredtechnologiesdo you have a small papa pump?
