English FAQ
Q1: Model code explanation
- 180 / 250: Displacement
- DR: Pressure‑cutoff constant‑power control
- LR2: Load‑sensing constant‑power variable control
- 10R / 30R: Series version & right‑hand rotation
- PPB13N00 / FPB13N00: Port layout, mounting flange, seal and factory specification
Q2: Core advantages
Constant‑power control automatically adjusts flow with load changes to maintain stable power output; open‑circuit design for flexible system configuration, strong overload resistance, long‑life operation under continuous heavy‑load working conditions.
Q3: Compatibility
Standard OEM‑matched installation dimensions, fully interchangeable with original Rexroth A4VSO pumps, direct replacement without modification.
