FYI...

I've seen the inside of a Damitz valve and they are approx 8mm in diameter.

I recently changed my pump to a Damitz brushless pump (flow rate 450L a minute), Mr Damitz explained to me that its not about pressure, but about volume... albeit you still need pressure to lift a heavy object. ( I know very little about hydraulics :-) )

As an example, the release valve in my dumper is set to 10 bar, the steering is quicker than is was with a Jung pump running at 16bar, yet it'll still tip my daughter out the back and she weighes 17kgs aka 40lbs.

Without checking the flow rates of the Jung, I assume 0.3 equals 300l a minute?

With regards to the gear channel, you'd need to check whether you can mix that channel in your radio.

At 1500rpm and 20 bar this pump is supposed to move 440ml, it ruffly doubles at 3000rpm. I'm running a double planetary(at least 6:1) so my pump speed is pretty low. I think with the motor I plan to buy today and my current reduction I should be able to spin the pump at around 2200 max. With the relief set at 28 bar it has a fair amount of power so if I can get the volume up it should be OK. If need be I'll have to turn the pressure down but at 20 bar it will only drag itself across the smooth concrete until the stick is at 90 degrees. This machine is about the same size as a Vario so it requires a lot of juice!
