A4VSO180LR2/30L-PPB13N00 Steel mill industrial piston pump, German Rexroth axial piston pump

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.

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.
