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

LR2 Constant Power Control - Why It's Chosen in Plant & Field HPUs
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.
Typical Appliions
Industrial Plants: rolling mill auxiliary HPUs, forging press clamp circuits, stamping line power packs, injection molding machine aux pumps
Power Generation: turbine auxiliary hydraulic systems, gate/valve actuator supplies
Test Rigs: simulating load-limited hydraulic power sources

Frequently Asked Questions
Q1: What is the advantage of LR2 over DR or DFR in a plant HPU?
A1: DR/DFR control pressure or flow but do not inherently limit input power. LR2 actively limits motor input power (bar × L/min) — critical when your electric motor is sized near the pump's max power demand — preventing overload during high-pressure hold common in clamp/hold circuits.
Q2: What is the difference between PPB13 and PPB25?
A2: Both are SAE flanges/ports. PPB13 is the compact SAE port size for manifold-mounted skids; PPB25 uses larger SAE ports for high-flow piped systems. Pump performance is identical — select based on your hydraulic manifold or hose standard.
