The Bomag 05813287 Tandem Gear Pump is a genuine OEM tandem gear pump designed for Bomag BW 145 and BW 177 series single drum rollers as well as the BW 11 RH-5 pneumatic tyred roller. Sourced directly from Bomag, this pump matches the original component in form, fit, and hydraulic output — ensuring the machine's systems operate exactly as engineered. Compatible models include the BW 145 D-5, BW 145 DH-5, BW 145 PDH-5, BW 145 D-5 PL, BW 177 D-5, BW 177 DH-5, BW 177 PDH-5, BW 177 D-5 PL, BW 177 DH-5 PL, BW 177 PDH-5 PL, and BW 11 RH-5. When hydraulic performance matters, installing the correct OEM pump is the straightforward call.
Key Features
- OEM Hydraulic Precision — manufactured to Bomag's exact displacement and pressure specifications for this tandem pump, so flow rates and system pressure stay within design limits across both pump sections
- Direct-Swap Installation — matches the original mounting flange, port configuration, and shaft dimensions, dropping straight into place without machining or adapter fittings
- Broad Model Coverage — fits BW 145 and BW 177 single drum rollers across D-5, DH-5, and PDH-5 variants including PL configurations, plus the BW 11 RH-5 pneumatic tyred roller
- Sustained Hydraulic Output — a properly functioning tandem gear pump maintains consistent flow to both the drive and vibratory circuits simultaneously; a worn pump causes sluggish travel, reduced drum vibration amplitude, and overheating
- Genuine Bomag Part — part number 05813287 is an authentic Bomag component, verified against the OEM catalog for correct application and traceability
A tandem gear pump combines two gear pump stages in a single housing, driven by a common shaft. On these Bomag rollers, each stage supplies pressurized hydraulic fluid to a separate circuit — typically one serving propulsion and one serving the vibratory drum system — allowing both to operate simultaneously from a single pump body. When the pump wears internally, internal leakage rises, pressure drops, and the machine loses traction response or drum vibration force, often both at once. Replacing a failed tandem gear pump with a genuine OEM unit restores correct flow and pressure to each circuit independently, returning the roller to full compaction performance.
