Magom got the Jung pump, but keep in mind that the motor/tank/ is Magom's own set-up (cheap) and will not perform as good as the same Jung pump delivered with Premacon or Fumotec set-up...This Jung pump is prepared for fare larger machines than this loader and would probably be needed to be tuned down to 10-20% of max performance, if at all manage to fit it in the machine

Depends on what Jung pump they're using, do you know?

It's the HR-7 / 4003. Magom does not use a reduction transmission, to keep cost down, installed a oversized motor in order to reduce the rpm. But I personally think it runs higher at full speed than the recommended 3-4000 max rpm for the pump. Too small tank (50-100 ml, vs Premacon 500 ml), no good cooling of the oil, which then more quickly gets hot and start foaming. Magom got much nice suff now, as the tracked loader, but they still got some way to go concerning their pumps, IMO.

4003 is 0,45ml/rev, way too much volume for these tiny bore short stroke cylinders!

I started with that pump in my Fumotec 490, it was like operating a pneumatic system, too fast - kinda springy movements. I put that pump in my JD850 & with it's much larger cyl bores, it's perfect speed, especially on the twin 18's lifting the boom.

I doubt Magom pays any attention to this forum, so my words are meaningless...
