High pressure pump

[ruben]

Hola
Quiero planos para bomba de alta presión

Alguien me puede ayudar

Perdón por muy inglés, estoy para España.

It is all Greek to Me.

hello

What kind of pump? It would help people to know what you are after.

Very true!

What is considered high pressure?
What do you want to pump?
Volume per time?
Energy source you have in mind?
Are you in it for the build fun, or just want a pump? (make or buy or re-purpose?)
Pumps are relatively cheap compared to the effort to make one.

Greetings Timo

¡Muy cierto!


¿Qué se considera alta presión?
¿Qué quieres bombear?
¿Volumen por tiempo?
¿Fuente de energía que tienes en mente?
¿Te interesa construir por diversión o simplemente quieres una bomba? (¿hacer, comprar o reutilizar?)
Las bombas son relativamente baratas en comparación con el esfuerzo que supone fabricarlas.

Saludos timo

Hola quiero bombardear lodo
presion max 400 bares

es por diversion

English... Just use an online translator...

I see 400 bar... that's a lot. Is it for a diesel or something like a hydrostatic pressure tester?

Google translates to "bomb mud",...I don't know what that might mean.

Many home use pressure washer pumps will reach that pressure.

@Lloyd-ss has the highest pressure pump on this forum. Try messaging him, maybe. He has a failure point test set up that goes well above 400 Bar.

Pretty sure it lacks "bomb mud" though...

Inglés...Solo usa un traductor en línea...

Veo 400 bar... eso es mucho. ¿Es para un diésel o algo así como un probador de presión hidrostática?

Es para bombear una mezcla de lodos de arena, agua y arcillas

Start looking at "gear pump".
You can adjust your requirements from there.
At least it's a helpful answer, never seen so many "SA" answers.

I'm pretty sure the sand in the mixture ruben needs to pump will destroy a gear pump rather quickly.

Best to look at centrifugal or Tesla pumps; they wont produce the pressure he wants, but at least they can handle pumping abrasives.

and a piston pump

and a piston pump

I don't believe you can use a piston pump to move a water + sand + clay mixture.

The only pump likely to survive is a Tesla pump.

Commercially, very high pressure mud is often pumped with plunger (not piston, I explicitly mean plunger) pumps tied to hydraulic cylinders or air cylinders. A 4 valve double acting piston pump layout also exists but my limited knowledge is that those are only for bentonite slurry aka drilling mud vs literal mud.

I am assuming you mean literal mud as in dirt.


Before someone jumps on me about piston mud pumps:
I'm sure piston mud pumps exist but with plunger pumps, the packing is easily changed and the lack of internal interference means no metal on sand coated metal wear points.


If you google "live steam boiler plunger pump" you will get a bunch of ideas on the basic layout of a simple plunger pump. Then just scale the design.

YouTube has some videos of hydraulicly actuated mud plunger pumps, but I can't seem to find one to link to.

Ruben's post #10 translates to "sand, water, and clay sludge". When I think of sand, I imagine pumping water with beach sand in it. How can valves properly close in those conditions? Is it a matter of how fine the sand grains are?

 

[The Ignoble Troll]

I'm no expert but my guess is that for a mixed media slurry pump they probably use wear resistant valves like TPU or castable Urathane and something poppet styled so that the seal is flexible and wear resistant.

I would also guess that valve sealing is not perfect but rather "good enough" while pumping.

All the mud (again not drilling mud) pumps I've seen have fairly large plungers which would mean that a bit of back leakage would be moot.

Reaching 400Bar would mean a small diameter plunger... basically a force multiplier device.

Some castable urethane compounds (check out the offerings from Smooth-On https://www.smooth-on.com/category/urethane-rubber/) could potentially be excellent packing AND valve sealing material.

edit: I added a gif of a crank driven plunger pump.

 

[The Ignoble Troll]

This one uses pistons, not plungers, and huge ball check valves.

 

[ruben]

yes are good idea

Concrete is routinely pumped many stories up, for constructing new concrete buildings.
