Product Overview

The Rexroth A4VSO180LR2/30L-PPB13N00 is a genuine German-manufactured A4VSO series open-circuit axial piston variable pump, equipped with LR2 constant power (horsepower) limiting control. With a displacement of 180 cm³/r and PPB13 SAE compact flange & ports, this pump is specifically suited to heavy-duty industrial hydraulic power units—particularly in steel mills, rolling lines, continuous casting machines, and furnace hydraulics—where electric motor power must be strictly limited to prevent overload during high-pressure hold conditions.

The LR2 control automatically reduces pump displacement as system pressure rises so that input power (pressure × flow) stays within a preset limit, ensuring safe and efficient operation of fixed-speed AC motor drives commonly found in plant-wide hydraulic stations.

LR2 Constant Power Control Benefits for Steel Mill HPUs

In steel plant hydraulic power units, large pumps often run on fixed-speed motors with defined kW ratings. LR2 control prevents motor overload:

  • Pump delivers full flow at low system pressure
  • As pressure builds (e.g. during clamp hold or roll positioning), displacement is reduced to keep motor power below the preset limit
  • Avoids nuisance tripping of motor overload relays / thermal protectors
  • Adjustable power setpoint to match your motor's rated capacity
  • Ideal for rolling mill screwdowns, furnace door clamps, coil car hydraulics, and caster segment adjustment circuits

➡ PPB13 porting is often selected for compact manifold integration on skid-mounted plant HPUs.


Typical Applications
  • Steel & Metals: rolling mill hydraulic stations, continuous caster clamp & guide circuits, furnace door/cover hydraulics, coil handling systems
  • Heavy Industry: forging press auxiliary pumps, extrusion press HPUs, heavy stamping lines
  • Power Plant: turbine auxiliary hydraulic systems, gate/valve actuator hydraulic supplies
  • Industrial Test Rigs: simulating load-limited hydraulic power sources
  • Large Machine Tool Hydraulic Power Units

Frequently Asked Questions
Q1: What is the advantage of LR2 over DR control in a steel mill HPU?
A1: DR simply holds a set pressure and destrokes when reached. LR2 actively limits input power (bar × L/min)—critical when your electric motor is sized near the pump's max power demand. It prevents motor overload during high-pressure hold, which is common in mill stand clamps and position-hold circuits.
Q2: What is the difference between PPB13 and PPB25 on A4VSO180?
A2: Both use SAE flanges/ports. PPB13 is the compact SAE port size, commonly used on manifold-mounted HPUs in plants; PPB25 uses larger SAE ports for high-flow piping. Pump performance is identical—selection depends on your hydraulic manifold or hose standard.
Q3: Can this pump be used in a closed-circuit travel drive?
A3: No. The A4VSO series is for open circuit (open loop) only. For closed-circuit track/wheel drives, use the A4VG or A4VM series.
