The Bomag 05813276 Tandem Gear Pump is a genuine OEM tandem gear pump designed for BW 138 AD-5, BW 135 AD-5, and BW 138 AC-5 tandem rollers. Sourced directly from Bomag, this pump meets the exact specifications your machine was built with, ensuring correct flow rates and pressure outputs with no guesswork on compatibility. This tandem gear pump installs directly into the hydraulic system of these tandem rollers, restoring full hydraulic function to both drive and auxiliary circuits.
Key Features
- OEM-Grade Hydraulic Precision — manufactured to Bomag's exact flow and pressure specifications, so both pump sections deliver the output your tandem roller's hydraulic system demands
- Direct-Fit Replacement — engineered to match the original mounting configuration and port layout of the BW 138 AD-5, BW 135 AD-5, and BW 138 AC-5, allowing a straightforward swap without machining or adaptation
- Verified Fitment — confirmed for Bomag BW 138 AD-5, BW 135 AD-5, and BW 138 AC-5 tandem rollers, with part number 05813276 matching the factory parts catalog
- Dual-Circuit Hydraulic Coverage — the tandem design serves two hydraulic circuits simultaneously, keeping both drum drive and auxiliary functions supplied from a single pump assembly
- Protects Against Costly Downstream Damage — a worn or failing gear pump starves the hydraulic system of flow, leading to sluggish drum response and accelerated wear on valves and motors; this genuine OEM part restores proper system protection
A tandem gear pump combines two gear pump sections in a single housing, driven by a shared shaft, so one unit can supply hydraulic pressure to multiple independent circuits at once. In a tandem roller like the BW 138 AD-5 or BW 135 AD-5, this typically means simultaneous feed to the propulsion and vibration or steering circuits, keeping all hydraulic functions operating in balance. When the pump wears internally — through gear tip erosion or seal degradation — flow volume drops, pressure becomes erratic, and the roller loses responsive control over its drums, making timely replacement essential to maintaining consistent compaction performance.
