The Bomag 05818403 Pump Head is a genuine OEM component designed for the BW 900 AD tandem roller and BW 900-2 and BW 900-50 walk-behind rollers. Sourced directly from Bomag, this pump head delivers an exact match to the original specification, ensuring a correct, trouble-free installation. Whether you are servicing a BW 900 AD or maintaining a BW 900-2 or BW 900-50, this part is the factory-correct choice to restore your machine to full operating condition.
Key Features
- Genuine OEM Hydraulic Integrity — manufactured to Bomag's original tolerances for precise pressure control and leak-free pump head sealing, critical in hydraulic pump assemblies where dimensional accuracy directly affects system performance
- Direct-Fit Replacement — engineered to the same specifications as the original, this pump head seats and connects the same way as the part it replaces, with no rework needed
- Verified Fitment — confirmed for the BW 900 AD tandem roller and BW 900-2 and BW 900-50 walk-behind rollers, covering both ride-on and pedestrian variants in the BW 900 range
- Sustained Hydraulic Output — a correctly functioning pump head maintains consistent hydraulic pressure delivery; a worn or damaged head leads to pressure loss, erratic drum vibration, or propulsion failure
- Authentic Bomag Part — supplied as a genuine OEM component under part number 05818403, ensuring full traceability and confidence in the part you are installing
The pump head forms a critical sealed interface within the hydraulic pump assembly, controlling fluid flow and maintaining the internal pressure necessary to drive the machine's hydraulic circuits. When this component wears, cracks, or loses its sealing ability, hydraulic pressure drops and the machine's drum drive, vibration system, or propulsion can be compromised. Replacing a degraded pump head with a genuine Bomag part restores proper hydraulic function and keeps the compaction system operating as intended.
