The Bomag 05804420 Pump Unit is a genuine OEM component designed for BW 124 and C 815 C series 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, and C 815 C. As a direct Bomag OEM part, this pump unit meets the exact specifications required by these machines, ensuring a proper fit without improvisation or adaptation. Sourced directly from Bomag's authorized parts catalog, part number 05804420 is the correct replacement when the original unit requires service or renewal.
Key Features
- Genuine OEM Hydraulic Integrity — manufactured to Bomag's exact flow rate and pressure tolerances, so the hydraulic circuit performs as the machine was designed to operate
- Direct-Fit Replacement — matches the original mounting configuration and port layout on BW 124 and C 815 C single drum rollers for a straightforward swap
- Broad BW 124 and C 815 C Coverage — confirmed fitment across the BW 124 DH-3, BW 124 PDH-3, BW 124 DH-4, BW 124 PDH, BW 124 DH-40, BW 124 PDH-40, BW124PDH-40, BW124DH 4, BW124PDH 3, C 815 C, and C815D single drum rollers
- Sustained Compaction Output — a properly functioning pump unit maintains consistent hydraulic pressure to the drive and vibration systems, keeping compaction force steady across the full working pass
- OEM Part Number Confidence — ordering by part number 05804420 eliminates guesswork and ensures you receive the exact unit specified for these machines
The pump unit is the hydraulic heart of the roller's drive and vibratory systems, converting mechanical engine power into pressurized hydraulic flow that powers propulsion, drum vibration, and steering functions. When the pump unit degrades or fails, the machine may exhibit sluggish travel, reduced drum vibration amplitude, or complete loss of hydraulic drive — all of which bring compaction work to a halt. Replacing a worn pump unit with a genuine OEM part restores full hydraulic output and allows the single drum roller to deliver consistent, spec-grade compaction performance.
