A4VSO125LR2/30L-PPB13N00 German made A4VSO125 piston pump from Rexroth Industrial Mining Oilfield

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.

Working ports 13 and 25, flat key splines p and z, seals p and v, control mode: dr, displacement: 125 (r forward rotation)

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:

• Delivers full flow at low system pressure (fast cylinder advance/retract)
• As pressure builds (clamp hold, pressurization, valve actuation), displacement is reduced to keep motor power below the preset limit
• Avoids nuisance tripping of motor overload relays / thermal protectors
• Adjustable power setpoint to exactly match your motor's rated capacity
• Simple spring-set adjustment — no pilot pressure required (see LR2G for pilot-influenced version)

➡ PPB13 compact SAE porting is ideal for manifold-integrated HPU skids found in plants, mine sites, and oilfield packages.
