Which hyd excavator pump/setup for a newbie

[Lil Giants]

I've been using Leimbach hyd systems for yrs & they're great for small scale models using 12-14mm bore pistons with 2mm ID plumbing for reasonably quick cycle times.

The 200 pump will be the mini with a brushless motor that is used primarily to operate their trk crane, not meant for long continuous operation.

The 450 pump was originally for their telescope cylinders & the brushed motor was bi-directional. Is it now mono directional for use with valves? I don't know.

The 380 pump, I knew as a 350ml/min pump, but maybe the 380 version is with the brushless motor on it running at 8000rpm, instead of the 6000rpm brushed motor. A faster turning pump, you'll just wear it out quicker if left running all the time. Todays more sophisticated radios with channel mixing, you can limit the wear & heat build up by making the pump activate only when necessary... makes your run times last longer too.

Just been informed by Der Getriebedoktor, the supplied pump with their Bruder cat 320 conversion is the 380 ml pump. The same or similar to the Wedico Cat 345d I believe, runs at 12 bar on the brushed motor. Could somebody in the know inform me what the ml figure means in pump terms. Is it the capacity of the oil tank, or the ml pumped per minute.
Does it mean the 380 would be able to supply more / bigger cylinders than say the 200 size , but at the same pressure ?
Thanks
