The Rexroth A4VSO125LR2/30L-PPB13N00 is a genuine German-manufactured A4VSO series open-circuit axial piston variable pump, featuring LR2 constant power (horsepower) limiting control. With a displacement of 125 cm³/r and PPB13 SAE compact flange & ports, this pump automatically reduces displacement as system pressure rises so that input power (pressure × flow) stays within a preset limit—protecting fixed-speed electric motors from overload.
The LR2 control is highly valued in industrial plant hydraulic power units, mining surface installations, and oilfield skid-mounted HPUs, where drive motor capacity is carefully matched to pump output. The compact PPB13 porting is typically selected for manifold-mounted plant skids. Rated for 350 bar continuous / 400 bar peak.

In plant-wide hydraulic stations and oilfield skid HPUs, pumps are driven by fixed-speed AC motors with defined kW ratings. LR2 prevents motor overload:
➡ PPB13 compact SAE porting is ideal for manifold-integrated HPU skids found in plants, mine sites, and oilfield packages.
