Very nice workmanship. Have you done any testing by running water into the ports? If so what rpm were you able to turn? I'm very interested in a similar application as a very small scale generator and I'm curious as to what to realistically expect in rpm with a very small load. Thanks.
@jbhelix108 This pump is designed to flow outward, it would do very poorly trying to reverse the flow. The smooth disk doesn't created enough torque to be used as a generator. You need to look at building a Pelton style wheel
@tinkerman01 Yup I know what you mean about the torque. In my applicaiton though I'm not trying to go big on the current I need to generate. It will be measured in milliamps not amps and single digit volts. To most people in the Hydro world that seems like poor performance. But it isn't if that was your purpose driven goal to begin with. More important in my application is compact and being able to use a failry modest amount of liquid flow.
@tinkerman01 Thankfully I won't need a ton of RPMs to drive this scale generator. That may actually be the number one reason not to use a tesla turbine in my app. As it will probably want to over rev my geny. I'm going to play around with some things in this scale and see what I can come up with. I may end up with a more traditional style turbine or a combo of Tesla and impeller style. Really, thanks for some great inspiration.
Great pump! Do you have instructions and a parts list to build this design? What type of bearings are you using, how many, and where did you buy them? Would you be able to build another and sell it and if so, how much would it be ;-) ? Keep it up!
P.S. Do you have or will you do a video of it running as a turbine (reverse pump)?
I saw the video and it is awesome. I have heard that these pumps can also be used for pumping air and as a vacuum pump. I am curious to know what modifications would need to be made to use the pump for this purpose.
Have you tried to build a Valvular Conduit? Try hooking it up to the input and out put of the pump. Also what is the spacing between plates and any chance of seeing how you made it? Nice job, thank you!
Hi, I've been watching your pump, both versions and now I'm building a version myself. No plans just inspiration from your video and my own ideas. Could you post a dismantling of the shaft and bearings? I'm looking into installing the shaft and bearings in a brass sleeve. that way I can make different sleeves/shaft/disc setups for different uses and swap them easily.
Yes, there is a gap between washers. The gap can be .010-.060 inch depending on what fluid is being pumped. A wider gap is more efficient for thicker viscosity. The effects of the pump will vary greatly between viscosity.I have done hours of testing on these little pumps and have found the best gap for many different fluids. On the pump in this video the washers are held in place by friction, yes. I have build other pumps that requires a key way or a pinned disk.

the bearings are sealed from the water

is it watertight because of sealed bearings? Thanks!

Tinkerman,
Have your tried to use this as a vacuum pump?

How does this configuration work as an air/vacuum pump?
stevekc84 1 year ago
@stevekc84 . It is a water pump. Visit my channel to see this pump in action.

Is there any gap in between washers? Is washer held in place only by friction?

you should be selling these
mass manurfacture and then on ebay
you will sell many as it has a huge amount of uses
