High Pressure Rexroth Plunger Pump A4VSO71LR2/10R-VPB13N00 A4VSO71LR2/10R-PPB13N00 A4VSO71DRG/10R-VPB25N00

A1: The model code encodes key design and configuration details:

• A4VSO: Series identifier (A=Axial piston pump; 4=Size series; V=Variable displacement; S=Swashplate design; O=Open-circuit application)
• 71: Nominal displacement (71 cm³/r at maximum swashplate angle)
• LR2: Control mode (LR=Hyperbolic power control; 2=Enhanced version with optimized power limiting response)
• 10R: Mounting and rotation specification (10=Standard mounting flange per DIN 24336; R=Right-hand rotation when viewed from the drive end)
• VPB13: Seal and port configuration (VP=Variable pressure port thread type; B13=FKM seal material compatible with mineral oil and HFC fluids; 13=Standard port size)
• N00: Supplementary features (N=No special options; 00=Base model without additional accessories)

A2: Core nominal parameters (for mineral oil, operating temperature 40-60°C):

• Pressure: Nominal working pressure = 350 bar; peak pressure = 420 bar (short-term operation, ≤5% of total runtime); case drain maximum pressure = 6 bar
• Speed: Minimum stable speed = 600 rpm; nominal speed = 1500 rpm; maximum speed = 2200 rpm
• Flow: At 1500 rpm, maximum flow = 106.5 L/min (calculated by 71 cm³/r * 1500 rpm ÷ 1000); flow is infinitely adjustable via swashplate angle (0-100%)
• Power Matching: Requires a 37-45 kW drive motor (calculated by P = Q*p÷600, where Q=flow in L/min, p=pressure in bar)
