Nominal pressure 350 bar, peak pressure 400 bar. Rated speed 1800 rpm (maximum 2100 rpm) at Vg max; flow approx. 324 L/min at the rated speed; drive power approx. 189 kW and torque approx. 1002 Nm at Δp 350 bar; mass approx. 102 kg. Swashplate design for industrial open circuits, low noise level and short response times.
Supply is as a new aftermarket replacement unit, quality checked before shipping. Because the full model code defines mounting, seals, shaft and ports, please send us your complete nameplate code before ordering and we will confirm the exact configuration.
Control: DFR1 pressure and flow controller (load sensing)
Pressure and flow control for load-sensing circuits (DFR family); the pump follows load pressure and delivers only the required flow.
