Hey /diy/, after watching a video on ram pumps I've decided

Are you using water in the system?

Yes they will wear out, but you should get a decent lifespan from brass. Stainless Steel will probably be better, but more expensive.

Generally it is a rubber seal that wears first in swing check valves, not the metal body.

The rubber seal can usually can be replaced easily.

I have no idea what a ram pump is though?

If you're building a ramp pump like that, it's going to have to come apart periodically for cleaning and maintenance anyway. A yearly disassembly really isn't that often I would just use the brass ones and keep an eye out for if it becomes ineffective.

I built a working model years ago.

the swing check valves I'm looking at don't actually have an o ring. Here's a video of someone replacing a worn out check valve in there ram pump

Yeah I think you're right, I'm just going to go with brass, makes me wonder if you can just buy the internals instead of replacing the whole thing.

Pump maintenance for any kind of pump is annoying. If you plan on using it seriously, build two and keep a complete spare. I do that with conventional well pumps and it pays off because they never die at a convenient time.

guys guys guys, could I use this pump to pump sea water?

>>1121890
A hydraulic ram pump is a pump that uses the water hammer effect to use the energy of 10 gal of water falling 4 feet to pump 1 gal of water up 40 feet.

maybe? the only way I can think of to do it would be taking advantage of a tidal bore/tide pool that would let it run for an hour or two every day as the tide comes in.

there's some guides online for how to build a more adjustable drop check valve. honestly, I think that might be worth it, because I built one but haven't been able to get it working consistently. I cant tell if its leaves getting sucked in, or if it's that the ram pump is running slightly faster than the water source.

I would worry that every run of the flaps is a different size, I would expect that only the pipe size/thread is standardized

oh no did you watch wranglerstar?

Never heard of them. What a fascinatingly simple and elegant idea. I fucking love humans sometimes.

yep. they were never super common because 90% of the time you could just go higher and aqueduct, or use a waterwheel/spiral pump, and it wasn't invented until the late 1800's, but it was a preferred method for traditional british manor houses.
The other brilliant one from the era was using a chain and gear to connect a fan in the fireplace flue to a roasting spit, so the rising hot air spins the fan and slowly turns the spit.

Although I will say there is a conspiracy theory that the pyramids were giant industrial ram pumps to keep the fountains in Giza running and spraying mist everywhere to make it livable.
