Quite an impressive open pit operation you got going there) I would think there are not many of these machines around seeing that number of hours on the meter ...Vario/Fumotec might should hire you as a test driver, if they don't already do
I notice that both Vario/Fumotec and Premacon chose pump motors running at 8000-9000 rpm no load, 600-900KV, relative high imo. I've not seen a Vario 850 running live, but seeing your videos I hear the pump motor kind of struggle when running against the PRV. Have you turned up the PRV setting, or is it the factory setting, and the chosen motor might be a bit under-powered?
I've never been such an fan of these 'high rev' pump setups, and working at putting together my own 12V setup with a Jung HR7/4003 and a 360KV, with motor running at around 4000 rpm no load, pump 3000 rpm, which will hopefully reduce the noise, wear of bearings and transmission parts (belt) a bit compared to the german setups. Time will show)
