What oil flow and pressure does each vibratory pile driver model need?

Question

VANROCK Group · Accepted Answer

The Standard Hammer range is set at 300 bar on all three models, but each model needs a different oil flow range.

- VR-SH 25: 300 bar, 150–170 LPM
- VR-SH 30: 300 bar, 180–220 LPM
- VR-SH 40: 300 bar, 240–260 LPM

Frequency also changes by model, so the hydraulic supply needs to match the hammer you choose. VR-SH 25 runs at 3,300–3,600 rpm, VR-SH 30 at 2,800–3,600 rpm, and VR-SH 40 at 3,000–3,250 rpm. If the excavator cannot provide the required oil flow at the specified pressure, the hammer will not operate in its intended working range.
