The Bomag 05813299 Hydraulic Tandem Gear Pump is a genuine OEM component designed for Bomag BW 100 and BW 120 series tandem rollers, including the BW 100 AD-5, BW 100 AC-5, BW 100 SL-5, BW 120 AD-5, BW 120 AC-5, BW 120 SL-5, BW 120 SLC-5, BW 115 AC-5, BW 131 AD-5, and BW 131 ACW-5. Sourced directly from Bomag, this pump matches the original unit's porting, shaft dimensions, and flow characteristics — no adaptation needed to drop it into place. Whether you are restoring hydraulic pressure after a pump failure or completing a scheduled overhaul, this part delivers the exact output your machine's hydraulic circuits require.
Key Features
- Genuine OEM Hydraulic Specification — manufactured to Bomag's original flow-rate and pressure tolerances, ensuring both gear sections of the tandem pump deliver the correct output to the machine's drive and auxiliary hydraulic circuits simultaneously.
- Direct-Swap Fitment — matches the original mounting flange, shaft spline, and port configuration, allowing straightforward installation on covered BW-series tandem rollers without remanufacturing or adapter fittings.
- Broad BW-Series Coverage — fits BW 100 AD-5, BW 100 AC-5, BW 100 SL-5, BW 120 AD-5, BW 120 AC-5, BW 120 SL-5, BW 120 SLC-5, BW 115 AC-5, BW 131 AD-5, and BW 131 ACW-5 tandem rollers.
- Restored Hydraulic Performance — a worn or failed tandem gear pump causes sluggish drum drive response, erratic vibration control, and steering hesitation; this replacement restores full hydraulic pressure and flow to bring the machine back to rated compaction output.
- Verified Part Number 05813299 — cross-reference this number against your Bomag service documentation before ordering to confirm application accuracy for your specific machine serial range.
A hydraulic tandem gear pump combines two gear pump sections within a single housing, driven by a common shaft. Each section supplies pressurized hydraulic fluid to a separate circuit — typically one serving propulsion or drum drive and the other serving auxiliary functions such as vibration or steering. Because both sections operate from a single driven unit, a failure in either gear set affects overall machine function immediately. When the pump wears internally, internal leakage increases and flow drops, resulting in loss of drive force, reduced compaction performance, and potential overheating of the hydraulic system. Replacing this pump with a genuine Bomag unit restores correct circuit pressures and keeps both hydraulic systems operating within their intended parameters.
