The Bomag 05813178 Gear Pump is a genuine OEM component designed for BW 145-series and C 825 C single drum rollers. Sourced directly from Bomag, this gear pump meets the original equipment specifications required to keep the hydraulic system operating at the correct pressure and flow rate. It is a direct replacement for worn or failed units on compatible machines, including the BW 145 D-3, BW 145 DH-3, and BW 145 PDH-3. Confirm your model and serial range before ordering to ensure a correct match.
Key Features
- Genuine OEM Hydraulic Precision — manufactured by Bomag to the exact displacement and pressure tolerances specified for the original hydraulic circuit, ensuring correct flow delivery from the first startup
- Direct-Fit Replacement — mounts to the existing hydraulic circuit connections on compatible BW 145 and C 825 C single drum rollers with no adaptation or rework required
- Broad BW 145 Series Coverage — fits BW 145 D-3, BW 145 DH-3, BW 145 PDH-3, and related BW 145 variants, as well as the C 825 C single drum roller
- Restored Hydraulic Flow — a worn or damaged gear pump causes loss of drive force, erratic drum vibration, and sluggish steering response; replacing it restores full hydraulic output and consistent compaction performance
- Verified Part Number Traceability — part number 05813178 is the Bomag OEM reference, making it straightforward to cross-reference against your machine's service manual or parts catalog
A gear pump is the heart of a roller's hydraulic system, converting mechanical engine power into pressurized hydraulic flow that drives the drum, propulsion circuit, and steering functions. When the gear pump wears internally — through scoring of the gear teeth or housing — flow volume drops, pressure becomes inconsistent, and the machine loses the drive and compaction force needed to meet spec. Replacing a failing gear pump with a genuine OEM unit like part number 05813178 restores the hydraulic system to its designed operating parameters, keeping the roller productive and compaction results consistent pass after pass.
