The Bomag 05813175 Gear Pump is a genuine OEM component designed for Bomag tandem rollers including the BW 202 AD-4, BW 161 ADH-4, BW 190 AD-4, BW 203 AD-4, BW 203 ADO-4, BW 203 AD-4, BW 205 AD 4, BW 202 AD-4 EU-Flex, and BW 161 ADH-4 CHINA. Sourced directly from Bomag, this gear pump meets the exact specifications of the original unit it replaces. Correct hydraulic output is critical to drum drive and vibration system performance, making part number 05813175 a key service item during hydraulic maintenance or pump failure repair.
Key Features
- Genuine OEM Hydraulic Output Spec — manufactured by Bomag to the precise flow rate and pressure rating required by these tandem roller hydraulic circuits, ensuring the pump performs exactly as the original.
- Direct-Mount Replacement — mounts to the original pump ports and drive interface without modification, allowing straightforward installation during scheduled service or field repair.
- Broad Tandem Roller Coverage — confirmed fitment across multiple BW AD-4 and ADH-4 series tandem rollers, including the BW 202 AD-4, BW 190 AD-4, BW 203 AD-4, BW 203 ADO-4, BW 205 AD 4, and BW 161 ADH-4.
- Sustained Hydraulic System Integrity — a properly functioning gear pump maintains consistent flow to the drum drive and vibratory circuits; a worn or failing pump causes erratic drum response, loss of vibration amplitude, or complete drive failure.
A gear pump is the hydraulic heart of a tandem roller's drive and compaction system. It converts mechanical input from the engine into pressurized hydraulic flow, feeding the circuits that power drum propulsion and vibratory functions. When a gear pump wears internally — through scoring of the gear teeth or housing — it loses volumetric efficiency, resulting in sluggish drum response, reduced vibration force, or overheating of the hydraulic system. Replacing a degraded pump with a genuine OEM unit like the Bomag 05813175 restores full hydraulic output and keeps the compaction system operating within its designed parameters.
