The Bomag 05901521 Pump Flange is a genuine OEM component designed for BC 972 RB, BC 972 RB-2, BC 1172 RB, and BC 1172 RB-2 refuse/landfill compactors, as well as the MPH 125 recycler/stabilizer. Sourced directly from Bomag, this pump flange matches the original mounting geometry and material specification, ensuring a secure, leak-free connection within the hydraulic circuit. Confirming part number 05901521 against your machine's service documentation before ordering is always recommended to ensure the correct fit across this multi-machine coverage range.
Key Features
- Genuine OEM Hydraulic Integrity — manufactured to Bomag's original material and dimensional specification, maintaining the hydraulic system's rated pressure capacity and sealing performance at the pump interface.
- Direct-Mount Replacement — machined to match the original bolt pattern and port alignment, allowing this flange to seat correctly against the pump housing without rework or shimming.
- Broad Equipment Coverage — fits BC 972 RB, BC 972 RB-2, BC 1172 RB, and BC 1172 RB-2 refuse/landfill compactors and the MPH 125 recycler/stabilizer, making part number 05901521 a versatile stocking item for mixed fleets.
- Hydraulic System Protection — a correctly seated pump flange prevents fluid bypass and pressure loss; a worn or damaged flange can lead to pump cavitation, erratic hydraulic response, and accelerated component wear across the entire system.
- Pressure-Rated Sealing Surface — the machined mating face supports proper gasket or O-ring compression, critical for maintaining system pressure under the demanding duty cycles of refuse compaction and soil stabilization work.
The pump flange serves as the structural and sealing interface between the hydraulic pump and its mounting surface on the machine's drive or accessory circuit. It transfers the load of the pump assembly to the chassis or gearbox housing while maintaining a pressure-tight fluid path at the pump inlet or outlet port. When a pump flange cracks, warps, or corrodes, the sealing surface degrades — resulting in hydraulic fluid leaks, pressure drop, and potential pump failure that can take a machine out of service entirely.
