A4VG250EP4D1/32R-NZD10F071DH Hydraulic Pump

Nominal Displacement 250 cm³/rev Maximum displacement at 100% swashplate angle; adjustable via proportional control
Рейтинг давления (Continuous) 350 бар (5,075 psi) Long-term operating pressure for steady loads
Peak Pressure (Intermittent) 400 бар (5,800 psi) Short-duration pressure (≤ 10% of operating time) for heavy transient loads
Maximum Speed 2,000 rpm Shaft speed limit (exceeding may cause cavitation or bearing damage)
Minimum Speed 150 rpm Prevents insufficient lubrication or flow instability
Fluid Viscosity Range 10–800 mm²/s (cSt) Optimal: 20–400 mm²/s; use Rexroth-approved hydraulic oil (e.g., ISO VG 46)
Fluid Temperature Range -20°C to +80°C (-4°F to +176°F) Avoid temperatures < -10°C without winter-grade oil (risk of viscosity buildup)
