Wow 30 bar is a lot of pressure... what are you're hoses rated at?

Another option is mixing your pump to your valves in the radio.

Run the pump at 1/4 to 1/2 speed when the valves are closed, then when you operate the boom, stick or bucket the pump ramps up, in most digital radios you can program this.

Are you using the 0.3 or 0.46 Jung pump?
