Aluminum Rexroth Hydraulic Pump A10VSO45DR/31L-PPA12N00 A10VSO45DG/31R-PPA12N00

Q1: What does each segment of the model "A10VSO45DFR/31R-PPA12N00" represent?

A1: The model encodes key configurations: A10VSO - Series identifier (A=Axial piston pump, 10=Size series, V=Variable displacement, S=Swashplate design, O=Open circuit); 45 - Displacement (45 cm³/r at maximum swashplate angle); D - Mounting flange (DIN 24336, Type D); FR - Control mode (F=Flow control, R=Pressure limiting function integrated); 31R - Hydraulic control circuit (31=Standard control circuit, R=Right-hand rotation view from drive end); PPA12 - Seal and port configuration (PP=Pressure port thread type, A12=Seal material compatible with mineral oil); N00 - Supplementary features (N=No special options, 00=Standard version).

Q2: What are the key performance parameters (pressure, speed, flow) of this pump?

A2: Nominal parameters (mineral oil, 40-60°C): Pressure - Nominal working pressure 280 bar (suction port: max 10 bar, case drain: max 6 bar); peak pressure 350 bar (short-term, ≤5% operating time); Speed - Minimum stable speed 600 rpm, nominal speed 1500 rpm, maximum speed 2400 rpm; Flow - At 1500 rpm, max flow 67.5 L/min (45 cm³/r × 1500 rpm / 1000), adjustable via swashplate angle (0-100% displacement); Power - Matches 30-37 kW drive motor (calculated by P = Q × p / 600, where Q=flow in L/min, p=pressure in bar).
