The Bomag 05813163 Hydraulic Gear Pump is a genuine OEM component designed for BW 190 AD-4 AM and BW 203 AD-4 AM tandem rollers, including the BW 203 AD-4 AM EU-Flex variant. Sourced directly from Bomag, this hydraulic gear pump delivers an exact match to the original equipment specification — no guesswork on fit or function. Confirmed fitment covers the BW 190 AD-4 AM and BW 203 AD-4 AM series, making it a straightforward drop-in service replacement for these tandem roller models.
Key Features
- Genuine OEM Hydraulic Precision — manufactured by Bomag to the same flow rate and pressure tolerances as the original pump, ensuring consistent hydraulic output across the system
- Direct-Fit Replacement — engineered to match the original mounting configuration and port orientation on BW 190 AD-4 AM and BW 203 AD-4 AM tandem rollers for straightforward installation
- Confirmed Tandem Roller Coverage — fits BW 190 AD-4 AM, BW 203 AD-4 AM, and BW 203 AD-4 AM EU-Flex tandem rollers
- Sustained Hydraulic System Health — a properly functioning gear pump maintains the steady hydraulic flow that drives drum vibration and propulsion; a worn pump causes erratic compaction performance and potential system overheating
- Verified Bomag Part Number — order with confidence using part number 05813163, cross-referenced against Bomag's OEM catalog for accurate identification
A hydraulic gear pump is the heart of the machine's hydraulic circuit, drawing fluid from the reservoir and delivering pressurized flow to the motors and actuators that power drum vibration, propulsion, and steering. On tandem rollers like the BW 190 AD-4 AM and BW 203 AD-4 AM, consistent hydraulic pressure is critical to maintaining even compaction force across both drums. When the gear pump begins to wear, symptoms include reduced drum vibration, sluggish travel response, and rising fluid temperatures — all of which compromise compaction quality and can accelerate wear on downstream hydraulic components.
