The Bomag 05819100 Tandem Pump is a genuine OEM component designed for BW 177 and BW 145 series single drum rollers, including the BW 177 D-5, BW 145 D-5, BW 145 DH-5, BW 145 PDH-5, BW 177 DH-5, BW 177 PDH-5, BW 177BVC-5, and BW 177-5. Sourced directly from Bomag, this tandem pump delivers an exact OEM fit with no guesswork on compatibility. It is the correct replacement for operators and service technicians who need to restore full hydraulic function to their single drum roller quickly and with confidence.
Key Features
- Genuine OEM Hydraulic Output — manufactured to Bomag's original flow rate and pressure specifications, ensuring the hydraulic system performs exactly as designed for demanding soil compaction work
- Direct Drop-In Replacement — matches the original mounting configuration and port arrangement on the BW 177 and BW 145 series, allowing technicians to install this pump without adapting lines or fittings
- Broad BW Series Coverage — fits the BW 177 D-5, BW 145 D-5, BW 145 DH-5, BW 145 PDH-5, BW 177 DH-5, BW 177 PDH-5, BW 177BVC-5, and BW 177-5 single drum rollers
- Sustained Compaction Force — a properly functioning tandem pump maintains consistent hydraulic pressure to both drive and vibration circuits, preserving the roller's compaction output and grade performance
- Verified Part Number Integrity — ordering by Bomag part number 05819100 confirms you receive the exact unit engineered for these machines, eliminating the risk of receiving a mismatched pump
A tandem pump is a dual-section hydraulic pump that simultaneously supplies pressurized fluid to two independent circuits — typically the propulsion drive and the vibratory drum system — from a single power source. On Bomag single drum rollers, this component is critical: if either section of the pump loses output, the machine can lose traction, drum vibration, or both, compromising compaction quality and bringing work to a halt. A worn or failed tandem pump typically presents as sluggish travel, weak or absent drum vibration, or abnormal hydraulic heat buildup — all signs that replacement is needed to return the roller to full operating capacity.
