The Bomag 05813275 Tandem Gear Pump is a genuine OEM component designed for BW 138 AC-5, BW 138 AD-5, and BW 135 AD-5 tandem rollers. Sourced directly from Bomag, this pump meets the exact specifications required for proper hydraulic system operation on these machines. If your roller is showing signs of sluggish steering, weak vibration output, or inconsistent hydraulic response, this tandem gear pump is the correct OEM replacement to restore full system function. Verify your model against part number 05813275 before ordering to ensure a direct match.
Key Features
- Genuine OEM Hydraulic Precision — manufactured to Bomag's exact flow rate and pressure tolerances, ensuring the hydraulic circuits on your tandem roller perform as originally engineered
- Direct-Fit Replacement — this pump is engineered to bolt into the existing hydraulic circuit of the BW 138 AC-5, BW 138 AD-5, and BW 135 AD-5 without modification to ports, mounting, or drive connections
- Confirmed Tandem Roller Fitment — verified compatibility across the BW 135 AD-5, BW 138 AC-5, and BW 138 AD-5 tandem rollers, giving operators confidence in a correct parts match
- Dual-Circuit Delivery — as a tandem-style pump, this component simultaneously supplies two independent hydraulic circuits, making correct pump specification critical to machine operation
- Protects Downstream Hydraulic Components — a properly functioning tandem gear pump maintains consistent pressure and flow, preventing strain on valves, motors, and actuators caused by an under-performing or failed pump
A tandem gear pump is a dual-section hydraulic pump that delivers pressurized fluid to two separate hydraulic circuits from a single driven shaft. On Bomag tandem rollers, it typically supplies both the propulsion drive circuit and the vibration or steering circuit simultaneously, allowing the machine to handle multiple hydraulic demands at once. When this pump wears or fails, the result is reduced hydraulic pressure across one or both circuits, leading to loss of drive power, diminished drum vibration, or compromised steering — all of which directly impact compaction quality and machine control.
