The Bomag 05813113 Hydraulic Gear Pump is a genuine OEM Hydraulic Gear Pump designed for the BW 120 AD tandem roller. Sourced directly from Bomag, this pump is built to the same specifications as the original unit installed at the factory, ensuring a seamless fit into the hydraulic circuit of the BW 120 AD. When the hydraulic system demands consistent flow and pressure, this component delivers exactly what the machine was engineered to receive. Refer to part number 05813113 when ordering to confirm you have the correct unit for your BW 120 AD.
Key Features
- Genuine OEM Construction — Precision-manufactured to the original pump geometry and port specifications, maintaining correct hydraulic flow rates and pressure output for the BW 120 AD's system demands.
- Direct-Fit Replacement — Mounts to the existing hydraulic circuit interfaces on the BW 120 AD without modification, using the same port configuration and drive coupling as the original unit.
- Confirmed Fitment — Engineered specifically for the BW 120 AD tandem roller; verify with part number 05813113 before ordering to ensure correct application.
- Sustained Hydraulic Performance — A properly functioning gear pump maintains the steady pressure and volume the BW 120 AD needs for smooth drum drive and steering response; a failing pump causes erratic operation and loss of drive.
- Long Service Life — OEM-grade internal gears and housing tolerances resist wear under continuous hydraulic load, supporting extended intervals between pump replacements.
A hydraulic gear pump is the heart of a machine's hydraulic system — it converts mechanical power from the engine into pressurized hydraulic fluid that drives the drum motors, propulsion circuit, and steering on the BW 120 AD tandem roller. When the pump wears or fails, fluid pressure drops, causing sluggish or unresponsive drum drive, poor steering control, and potential overheating of the hydraulic system. Replacing a worn pump with a correct-specification unit restores full system pressure and keeps the roller operating as intended.
