BOMAG BW211D-40 Hydraulic Pump | 05817054 05818893 | Road Roller Parts

LIC Hydraulic provides the premium Hydraulic Piston Pump for BOMAG BW211D-40 Road Rollers, specifically optimized for part numbers 05818893 and 05817054. This high-pressure axial piston pump is the powerhouse behind the machine’s hydrostatic drive system. Engineered for the brutal vibrations and high-load cycles of soil compaction, this pump delivers smooth acceleration, precise directional control, and maximum gradeability. Whether you are performing a scheduled overhaul or a critical field repair, our 05818893 series pump ensures your BOMAG roller returns to peak performance with OEM-level reliability.

Technical Highlights

• Precision Engineering: Direct replacement for BOMAG PN: 05818893 / 05817054, ensuring $100\%$ compatibility with the machine’s hydraulic logic.

• High-Pressure Reliability: Rated for continuous operation up to $400\text{ bar}$, providing the torque necessary for steep climbs and heavy soil resistance.

• Integrated Charge System: Features an onboard charge pump to maintain circuit pressure and cooling during rapid reversals.

• Durable Swashplate Design: Optimized for high-frequency vibration environments, characteristic of single-drum rollers.

Application Areas

• Soil Compaction: Primary drive unit for BW211D-40 rollers on highway and infrastructure projects.

• System Refurbishment: The definitive solution for machines experiencing “loss of traction” or internal bypass issues.

Expert Maintenance Tips

• Case Priming is Mandatory: Always fill the pump housing with filtered hydraulic oil through the drain port before engine startup. Dry running for even $30$ seconds can destroy the piston slippers.

• Filtration Vigilance: Replace the high-pressure and suction filters every $500\text{ hours}$. Contamination is the leading cause of swashplate scoring in 05817054 models.

• Monitor System Temperature: Ensure the roller’s oil cooler is clean. Operating at temperatures above $90\text{°C}$ will rapidly degrade the pump’s internal seals and volumetric efficiency.
