The Bomag 05729296 Coolant Pump is a genuine OEM component designed for BW 177 and BW 179 series single drum rollers, including the BW 177 DH-4, BW 177 DHC-4, BW 177 PDHC-4, BW 177 PDH-4, BW 179 DH-4, BW 179 DHC-4, and BW 179 PDH-4. Sourced directly from Bomag, this coolant pump meets the same specifications as the original unit installed at the factory. It installs directly in place of the failed or worn pump, restoring proper coolant circulation to your machine's engine without the guesswork of adapting a non-spec component.
Key Features
- Genuine OEM Circulation Performance — Built to the exact flow and pressure specifications of the original, ensuring consistent coolant delivery under full working load on your single drum roller.
- Direct-Fit Replacement — Matches the original mounting configuration and port dimensions of the BW 177 and BW 179 series engines, dropping in without modification.
- Broad BW 177 and BW 179 Coverage — Confirmed fitment across the BW 177 DH-4, BW 177 DHC-4, BW 177 PDHC-4, BW 177 PDH-4, BW 179 DH-4, BW 179 DHC-4, and BW 179 PDH-4 single drum rollers.
- Engine Protection Under Load — A properly functioning coolant pump prevents overheating during extended compaction runs; a failing pump can cause thermal shutdown or engine damage in the field.
- Authenticated Bomag Part — Supplied as a genuine Bomag component under part number 05729296, giving you confidence that this part matches the engineering tolerances of your original equipment.
The coolant pump circulates engine coolant between the engine block and the radiator, drawing heat away from critical engine components and maintaining safe operating temperatures. On heavy-duty single drum rollers like the BW 177 and BW 179 series, where sustained high-load compaction generates significant heat, a functioning coolant pump is essential to continuous operation. When the pump fails — whether through impeller wear, seal deterioration, or bearing failure — coolant flow drops, engine temperature climbs, and the machine is forced into thermal shutdown, or worse, suffers internal engine damage.
