Are there any other way you could scan and put the catalog page on flicker.com or something ?
Alternatively: Do you have a link to the manufacturers site or the name of the manufacturer ?

I wonder if somebody on this forum can tell spot what theese adjustable hydraulic devices are ? (See pic): http://www.flickr.com/photos/14275989@N00/305132319/
The devices are inserted into a hydraulic block and looks like they are adjustable. Some numbers are written next to the devices on the...
Hello EdDanzer, we have looked into the possibility and we think that you might be correct. Using gear or piston pumps are probably not going to work. I have that info from several sources.
We are probably going to cancel the project.
Thank you anyway

Hello, Ashereng we are not based in the USA.
We are based in Europe.
We are working on a high volume project and need to find the correct suppliers.

Hi, we are looking for a low cost place to purchase hydraulic components like fixed orifices, flow valves, safety valves etc. Please recommend a webshop or a catalog outlet with a full selection. Thanks !

Hi, we can tolerate leakage as we dont measure the pressure or flow of oil. We do the torque sensing via a strain sensor external to the system mounted on a weight arm.
The rpm of the pump shaft gives the distance per time unit used to calculate power.
Will check out the surpluscenter ...
Hello KCJ, we are planning to build one for a similar but different application.
Yes, the car in the background is coupled directly to the
pumps via a wheel adapter. The oil is cooled down via some very large oil coolers. The valve is controlled via a sophisticated computer contol system...
Hello Zeusfaber.
That is interesting. However we might need faster response than 100 ms. I havent done 100% of the loop calculations yet but we will definately take a look at that unit there.
Thank you again.

Hello Zeusfaber, thank you for your input.
That might very well be a good idea. I dont know how a variable displacement pump works. Does the stroke of a piston pump change by the control input or something like that ?
However we have also found a very low cost way of making a very fast servo...
Waross, there is a real time control unit that adjusts the load on each of the sides so that the spider gear in the differential is not seeing any different RPM. This way the spider gear will not be stressed.
I have actually found out now that the system is cooled via some fans that are driven...
Hello all fluid pro's !
I have a picture of a hydraulic pump that is used for a
specific application and I need to try to find out what company makes this pump!
Do you by any chance know the manufacturer of the pump on the picture ? Do you know or can you estimate what kind of pump it is...
Hello Gunnar, thank you for your answer.
I don't think feeding energy back to the net is so easy as it sounds. It is AC and the generator will not be in sync with the net at all. The engine is the "master" The output had to be rectified and then switched with the correct 50 Hz frequency...
Hallo Waross, I will check that out. Thank you.
However I have the feeling that a genrator that powerfull will be very harvy. The equipment must be movable by hand.
What do you think ?

Alternative solution (question - what hydraulic pump can we use for this alternative) :
What about if we wanted to take the power straight from two wheel axles instead of one and run it thru the normal gearbox and shafts / differential of the car and reduce our demand for power to approx 550 HP...
Waross, this could be an option.
Do you know any manufacturers of this kind of retarders ?
Btw, I was thinking of the possibility of mounting several lower cost hydraulic pumps in paralell on a common axle driving them all. Then the paralell outputs of the pumps can drive a common flow...
Hello I know some ppl use a Thelma brake to do this in fixed installations. Thelma brakes are normally used as a manually applied brake for trucks. I think those thelma brakes are quite expensive as well.
I would assume a 600 kw generator + switched control electronics is very expensive :)...
Btw, I know this has been done with water brakes as the load element as well. However we want a "portable" system. This means the water flow neccessary to feed a water turbine as the load element will be far too high. We will need upstream water reservoirs and that is not feasable as it is too...
