The Bomag 05804392 Pump Unit is a genuine OEM component designed for BW 145 and C 825 C series single drum rollers. As a direct-from-Bomag replacement, this pump unit meets the original engineering specifications for these machines, delivering the hydraulic output your roller depends on. Confirmed fitment includes the BW 145 DH-3, BW 145 PDH-3, BW 145-DH-3, BW145DH 40, BW145PDH 40, BW 145 PDH 40, BW 145 DH 40, BW145 PDH 4, BW145DH 3, BW145PDH 3, and C 825 C single drum rollers.
Key Features
- Genuine OEM Hydraulic Precision — sourced directly from Bomag, this pump unit matches the original flow rate and pressure specifications required by your single drum roller's hydraulic system
- Direct-Fit Replacement — engineered to the same port configuration and mounting geometry as the original, allowing straightforward installation on compatible BW 145 and C 825 C models
- Broad BW 145 Series Coverage — fits BW 145 DH-3, BW 145 PDH-3, BW145DH 40, BW145PDH 40, and C 825 C single drum rollers, covering a wide range of this popular roller family
- Sustained Hydraulic Drive Performance — a properly functioning pump unit maintains consistent hydraulic pressure for drum drive and vibration circuits, ensuring the roller delivers full compaction force on every pass
- Long-Term Durability — built to Bomag's OEM material and tolerance standards, this unit resists the wear and thermal stress typical in continuous compaction work
The pump unit is the heart of a single drum roller's hydraulic system, converting mechanical engine power into the pressurized fluid flow that drives the drum, propulsion circuit, and vibration mechanism. When the pump unit degrades or fails, the machine loses hydraulic pressure — resulting in sluggish or unresponsive drum drive, reduced vibration amplitude, and ultimately an inability to meet compaction specifications. Replacing a worn pump unit with a genuine Bomag part restores full system pressure and flow, bringing the roller back to its rated compaction performance.
