The Bomag 05813155 Gear Pump is a genuine OEM component designed for Bomag single drum rollers including the BW 124 DH-3, BW 124 PDH-3, BW 124 DH-4, BW 124 PDH, BW 124 DH-40, BW 124 PDH-40, BW124DH 4, BW124PDH 3, BW124PDH-40, C 815 C, and C815D. Sourced directly from Bomag, this gear pump carries the same part number 05813155 used in the original factory build, so you can order with confidence that you're getting the correct unit for your machine. This pump slots in as a direct replacement, restoring hydraulic flow to OEM specification without the guesswork of sourcing an equivalent aftermarket unit.
Key Features
- Genuine OEM Hydraulic Integrity — manufactured to Bomag's original displacement and pressure ratings, ensuring the gear pump delivers the precise hydraulic output your single drum roller depends on for drum drive and vibratory system operation.
- Direct-Replacement Fitment — matches the original mounting face, port configuration, and shaft dimensions, allowing installation without machining or adapter fittings.
- Broad Single Drum Roller Coverage — confirmed fitment across the BW 124 DH-3, BW 124 PDH-3, BW 124 DH-4, BW 124 PDH-40, C 815 C, C815D, and related BW 124 variants.
- Sustained Hydraulic Flow Performance — a correctly functioning gear pump maintains consistent pressure across all hydraulic circuits; a worn or failed pump causes sluggish drum response, loss of vibration, and overheating of the hydraulic system.
A gear pump is the heart of the hydraulic system on a single drum roller, drawing fluid from the reservoir and pushing it under pressure to the drum drive motor, vibratory mechanism, and steering circuits. When the pump is functioning correctly, all hydraulic functions operate with full force and speed; as internal gears wear, volumetric efficiency drops, leading to weak or erratic drum vibration, reduced travel speed, and excessive heat buildup in the hydraulic fluid. Replacing a failing gear pump promptly with a genuine OEM unit like the Bomag 05813155 protects downstream hydraulic components from the damage caused by contaminated or low-pressure flow.
