It's a practical thing with such a small hydraulics tank, and I'm sure there is just enough oil in it in order to make the machine run smoothless, but what about heat development..? E.g Premacon use a pretty large tank, and much extra oil in the system, as a simple way of cooling.
Looking forward to hear how these valves and pump unit performs after some hours of running. I see no filter? The pump itself is well known to perform great, but I'm most curios about the valves, how leak-proof they will be. They are quite much cheaper than e.g. Premacon, naturally, and I might want to test them in my own machines in the future.
