Generators below of oil tank in order to heat dissipationWorking pump station pressure "0-30Mpa 1. Working pum station working pressure :15-24Mpa 2. Empty fast push/returen working pressure :7Mpa 3. Clamp pump station working pressure :4Mpa 4. Auto lift material oil pump pressure:5Mpa 5. Mandrel adjustment oil pum pressure:10Mpa 6. Hydraulic oil type 32-46,suitable temperature-40 / 80Mpa,Hei Yan recommend to use antiwear hydraulic oil.
