Tesla Turbine water pump

Tesla pump powered by a 1/3hp die grinder at 90psi working pressure. 9 disks 1.5" diameter. I am using the air grinder to power the pump. This is just a water pump, not free energy or anything special. This is a proof of concept that a flat disk can move a fluid very efficiently. I now use variable electric motors to power the pumps. Check my channel for more pump demos.

This is designed as a pump not a turbine.

@tinkerman01 Hello I am very interested about this type to pump and i'll like to build my own. I'll need to make a compact pump to push water min 10psi and min flow of 10L/min which seems extremely easy with this type of pump. Though i don't know where to start, and i have many questions on your video. How much is the input shaft speed? How much is the spacing between the disks for them to work for water fluid? Does the input diameter has to be bigger than the outlet diameter? +etc Thanks:)

@St0RM33This style pump really likes the high rpm, it preforms best the faster it spins,there is stalling out like a vane style pump. The testing with the 1.5inch model using water resulted the best pressure to rpm factor using a .020 disk spacing. The input rpm varied up to 19,000. The pump did not like rpm under 5k,but my 3.5 model runs at 3500. You will need more rpm for a smaller disk. Input diameter needs to be close to 50% of the disk dia. Make large ports that stay within the input dia.

hello, how many electricity could produce this turbine from the home water system ?

[St0RM33]

@tinkerman01 thanks. I will have about 0.8Kw of input power, so i it would be more than enough for my application. Though it's just a fun project, not something that i would use constantly. It is just the only motor i have in my hands so i'll have to use a gearbox to make it work;p

@St0RM33 This was my very first pump. The other update is the current design. The thinner the disk the more you can get in the housing. If you have any experience with a lathe you can make one. Nozzle design is determined by your application. Not sure what you need to research, I just applied my common knowledge with some trial and error. If you only need 10psi using 500rpm maybe this pump isn't for you. Maybe research other pump designs like gear or conventional pumps.

@tinkerman01 Continued: Also does the thinkness of the disks(not the spacing) and the material play a big role on the design? What about inlet cut shape, and output nozzle design? Can you recommend some theoretical/practical resources that i should start researching? I really don't want to make something like a copy of yours though i want to make something that works at least with not many modifications..Thanks, Ken

@tinkerman01 thanks so much for the info. probably a size like the one on this video will be ok for me. though i have only 100-500rpms input so i'll have to implement a step up gearbox around ratio 1:50 However this was the latest version of your pump? Because i saw one which it is like the original tesla design with two outlet ports, and 2 piece housing instaid of 3. But i fell it is very easy to construct the housing on a lathe.
