htomerif.Thank you for the advice:but this merely underlines my ignorance of such matters.And,while much worthless attention is paid to footballers,rockers,actors and the like no one ever mentions the engineers who keep our whole modern,technological running!Whether one likes or approves of this is not the point.No engineers-no medicine,no travel no nothing!
@Squarerig A lot of these are not new inventions, but things people do for CAD classes that have been around for a while. This, for example is called the "progressive cavity pump" and has actually been around since 1932.
it might be easier to produce an Archimedes propeller than it is to create a pump assembly with mating cylinder and shaft though. I would image casting would be possible but die tolerances might be a big PITA
i m facing a big problem the stator is not suitable for waste water and stator geeting warm , geeting very low pressure at discharge 0.3 BAR before using this pump you must cinfirm the nature of fluid wathever you want to pump , the Ph, viscosity, temprature etc .
yeah im pretty sure the no "pulsation" clam is a load considering at 0:40 it clearly demonstrate the pulsation of the output...Red...shaft...blue....shaft....red.....hmmm

I confess to being very impressed with all the new inventions that appear on Utube.My respect to all engineers involved.

@Squarerig
They are just stealing Archimedes' ideas.

So what are these pumps for?

lol, you turds. Did you miss the "liquid transfer" part of "liquid transfer flow without pulsation at any moment"

If you look at it, the 'marbles' are in constant motion, always moving forward with a constant speed. Compare that to a piston or diaphragm pump.

ok in a marble factory. no pulsation....thats just a load of marbles with two cavity discharges per revolution.
