I never realized how much friction had to be prevented in a pump like this. Amazing how much a little oil can do

Fantastic you dedicated so much time to teach others and share your knowledge. Lifesaver fella. Great stuff.

It'd be interesting if manufacturers looked at superhard low-friction coatings like BAM for the slippers and the port plate.

Very good explanation! Thanks a lot!

Bravo colleagues , thank you for lesson

Thanks a lot. Fantastic

Great video

Thanks sir

Thank you

Thank you 😀

Its through your explaination that doubts on piston Hyraulic pump got cleared. So in a variable pump the swash plate angles can be changed ? if so, is it done manually or automatically ?

Good day, I was wondering if you can maybe give me some advice, I just finished a full restoration on a small gas powered new holland skid steer, I have two of the 15 series sundstund axial piston pumps, closed loop with drive motors for the wheels, everything works great , good charge pressure and working pressure as I can drive into a pile and stall the 20hp engine, my only problem I think as I’ve never owned a skid loader is that I find it very noisy, like hydraulic whine , it just seems not right, it does get worst when warm or in lower rpm’s, I’m thinking of pulling a pump apart but I’m not sure what I’m looking for that would make this issue?, thanks for your time

Where do losses come from in a hydrostatic circuit? Aside from cost is there any reason why hydrostatic drives with wheelmotors are not a thing in road vehicles? I think it would be awesome to have a light truck which could run the powerplant at peak power or peak efficiency in any speed range, or convert peak power directly to peak torque.

why pumps are designed with an odd number of pistons(7 or 9)
