Rexroth A4VSO180LR2G/30L-PPB25N00 German Variable Axial Piston Pump The Rexroth A4VSO180LR2G/30L-PPB25N00 is a genuine German-manufactured A4VSO series open-circuit axial piston variable pump, equipped with LR2G constant power (horsepower) limiting control with pilot pressure limitation. With a displacement of 180 cm³/r and PPB25 SAE flange & ports, the pump automatically reduces displacement as system pressure rises so that input power (pressure × flow) does not exceed a preset limit — and the power setpoint itself can be influenced/limited via an external pilot pressure signal. This makes LR2G especially suitable for large industrial hydraulic power units driven by fixed-speed electric motors where motor overload protection is critical and where remote or pilot-assisted adjustment of the power limit is desired. Common in heavy presses, extrusion lines, and plant-wide hydraulic stations.

A4VSO180DRG/30R-PPB13N00ESO171 LR2G Constant Power Control - Key Benefits Compared to basic LR2, LR2G adds pilot pressure limitation capability: ➡ PPB25 SAE porting is selected when system plumbing uses larger SAE flanges for minimized pressure drop at high flow. Typical ApplicationsGlobal Distribution Distributed through Rexroth's authorized global dealer network, including: Frequently Asked QuestionsQ1: What is the difference between LR2 and LR2G on A4VSO pumps? A1: Both limit input power. LR2G additionally provides a pilot pressure port so the power limit can be influenced or externally constrained — useful for centralized HPUs or systems where multiple pumps' power sharing is managed from a common pilot source. Q2: Can LR2G prevent my electric motor from burning out? A2: Yes, when correctly set. LR2G ensures the pump will not draw more power than the preset value, helping avoid motor overload during high-pressure hold — provided the LR2G power setting matches your motor's rated capacity. Q3: Is a pressure relief valve still required? A3: Yes. A system pressure relief valve is still necessary as ultimate overpressure protection, even with LR2G control.
