Road Roller Vibratory Pump | 05817050, 05817054, 05818893 | Hydraulic Piston Pump

Road Roller Hydraulic Vibratory Pump (P/N: 05817050 / 05817054 / 05818893)

Product Overview: This series of hydraulic vibratory pumps consists of high-pressure axial piston pumps specifically engineered for the vibration systems of single-drum and tandem road rollers. As the power core of the compaction unit, these pumps provide rapid dynamic response for starting and stopping vibrations. Our models—including 05817050, 05817054, and 05818893—are strictly calibrated to match the hydraulic circuits of leading road machinery, ensuring smooth excitation and stable frequency.

Key Technical Advantages:

• Optimized for High-Frequency Reversal: Designed specifically for the frequent start/stop cycles of roller vibrations. The internal valve plates are reinforced to minimize wear from pressure spikes, extending service life in extreme site conditions.

• Superior Charge Performance: Featuring an integrated high-efficiency charge pump, it ensures stable back-pressure within the closed-loop circuit. This prevents cavitation and maintains peak performance during prolonged high-load vibration tasks.

• 100% OEM Compatibility: Manufactured strictly to OEM standards. All mounting flanges, shaft splines, and port layouts are identical to original part numbers like 05817054, enabling a seamless, “zero-modification” installation.

• Low Noise & High Volumetric Efficiency: Precision-ground piston groups and spherical porting technology ensure maximum volumetric efficiency even at 350 Bar operating pressures, while significantly reducing noise from hydraulic pulsations.
