What oil flow and pressure do the four side grip models need?

Question

VANROCK Group · Accepted Answer

All four models use a setting pressure of 300 bar. The required oil flow depends on the model size.

- VR-SG 15: 90–108 l/min
- VR-SG 25: 150–170 l/min
- VR-SG 30: 180–220 l/min
- VR-SG 40: 240–260 l/min

That hydraulic match is one of the first checks before selecting a unit. If the excavator falls in the right carrier class but cannot supply the model’s oil flow, it is not the right match. Frequency also varies by model, from 2,800 rpm up to 3,600 rpm depending on the unit. The pressure stays the same at 300 bar across the full range.
