The Bomag 05904274 Impeller is a genuine OEM component designed for BC-series refuse/landfill compactors and soil compactors, including the BC 473 RB-4, BC 473 RS-4, BC 473 EB-4, BC 672 RB-4, BC 772 RB-4, BC 772 RS-4, and BC 772 EB-4. Sourced directly from Bomag, this impeller meets the same specifications as the original part installed at the factory. It installs as a direct replacement, restoring proper fluid-moving performance to your machine's cooling or hydraulic circuit without adaptation. Confirm part number 05904274 against your machine's service documentation before ordering to ensure correct application.
Key Features
- Genuine OEM Impeller Construction — manufactured to Bomag's original blade geometry and material specifications, delivering the correct flow rate and pressure output the system was engineered for
- Direct Drop-In Replacement — matches the original mounting interface and rotational profile, so this impeller seats and aligns exactly as the factory part did
- Broad BC-Series Coverage — fits BC 473 RB-4, BC 473 RS-4, BC 473 EB-4, BC 672 RB-4, BC 772 RB-4, BC 772 RS-4, and BC 772 EB-4 compactors under part number 05904274
- Sustained Cooling and Flow Performance — a worn or damaged impeller loses pumping efficiency, causing heat buildup or inadequate fluid circulation; replacing it promptly keeps the system operating within spec
- OEM Part Number Traceability — carries Bomag part number 05904274 for straightforward reordering and parts-record accuracy across your fleet
An impeller is the rotating blade or vane assembly responsible for moving fluid — whether coolant, hydraulic fluid, or water — through a pump or fan circuit. As it spins, its blades generate centrifugal force that draws fluid in at the center and pushes it outward with pressure, keeping the system circulating at the volume and speed the machine demands. When an impeller cracks, erodes, or loses blade material, flow rate drops, pressure falls off, and the downstream system — whether an engine cooling jacket or a hydraulic actuator circuit — begins to run hot or sluggishly. On high-cycle machines like the BC-series refuse and soil compactors, where operating loads are sustained and demanding, restoring the impeller to original specification is essential for maintaining full machine output and avoiding cascading component damage.
