A4VSO180LR2G/30L-PPB13N00 Coal mine steel plant piston pump German Rexroth variable hydraulic pump

The Rexroth A4VSO180LR2G/30L-PPB13N00 is a genuine German-manufactured A4VSO series open-circuit axial piston variable pump, featuring LR2G constant power (horsepower) limiting control with pilot pressure limitation. With a displacement of 180 cm³/r and PPB13 SAE compact flange & ports, this pump is specifically suited to heavy-duty hydraulic power units in steel plants, rolling mills, coking plants, and coal mine surface installations.

The LR2G control automatically reduces pump displacement as system pressure rises so that input power (pressure × flow) stays within a preset limit, while the pilot port allows the power setpoint to be externally influenced—a critical feature when protecting fixed-speed electric motors that drive large plant HPUs. The compact PPB13 porting is commonly selected for manifold-mounted skid designs found in plant hydraulic rooms installations.

In steel mill and mine plant hydraulic power units, pumps are typically driven by fixed-speed AC motors with defined kW ratings. LR2G protects the prime mover:

• Delivers full flow at low system pressure for fast cylinder advance/retract
• As pressure builds (clamp hold, roll positioning, roof support pump station), displacement is reduced to keep motor power below the preset limit
• Pilot pressure port allows the power limit to be influenced from a central control system or by a supervisory pilot valve
• Prevents motor overload relay trips during high-pressure hold conditions
• Adjustable power setpoint to exactly match your motor's rated capacity

➡ PPB13 compact SAE porting is ideal for manifold-integrated plant HPU skids where space is limited.
