Key Features
- Genuine OEM Cooling Performance — manufactured to Bomag's exact flow rate and pressure specifications, ensuring the cooling circuit delivers consistent engine temperature control on the BW 138 AC-5
- Direct OEM Replacement — matches the original mounting footprint, inlet and outlet port sizing, and impeller geometry for a straightforward swap with no adaptation
- Confirmed Fitment — verified for the BW 138 AC-5 tandem roller, so you can order with confidence using part number 65270138
- Protects Engine Longevity — a worn or failing water pump causes coolant flow loss, leading to overheating and accelerated engine wear; replacing it promptly with a quality OEM unit prevents costly downstream damage
- Authentic Bomag Quality — backed by Bomag's OEM sourcing standards, this pump meets the same material and dimensional tolerances as the unit that left the factory
The water pump circulates coolant through the engine and radiator to maintain safe operating temperatures during compaction work. On a tandem roller like the BW 138 AC-5, sustained vibration loads and continuous operation put consistent demand on the cooling circuit, making a properly functioning pump critical to machine health. When the pump wears out — through seal failure, impeller erosion, or bearing degradation — coolant flow drops, engine temperatures rise, and the risk of serious overheating damage increases significantly.
