The Bomag 31780158 Water Pump is a genuine OEM component designed for BW 177 D-3 and BW 213 D-3 single drum rollers. Sourced directly from Bomag, this water pump matches the exact specifications of the original part, ensuring a direct, hassle-free installation. It is confirmed compatible with both the BW 177 D-3 and BW 213 D-3, giving operators confidence they are receiving the correct part for their machine. When your cooling system needs attention, replacing a worn pump with an authentic Bomag part keeps your roller running at the right operating temperature.
Key Features
- Genuine OEM Cooling Precision — manufactured to Bomag's original flow rate and pressure specifications, ensuring proper coolant circulation throughout the engine cooling system
- Direct-Fit Replacement — engineered to bolt into the same mounting position as the original pump, using the existing connections and hardware without rework
- Confirmed Fitment — verified for BW 177 D-3 and BW 213 D-3 single drum rollers under part number 31780158
- Engine Temperature Protection — a properly functioning water pump maintains consistent coolant flow, preventing overheating that can cause costly engine damage during heavy compaction work
- Long-Term Sealing Integrity — OEM-grade seals and impeller materials resist the heat cycling and operating pressures typical of roller engine environments, reducing the risk of coolant leaks over time
The water pump is responsible for circulating coolant through the engine and radiator, regulating operating temperature during continuous compaction cycles. Without adequate coolant flow, engine temperatures rise rapidly, leading to overheating, reduced power output, and the risk of serious internal engine damage. A failed or worn water pump — indicated by coolant leaks, overheating warnings, or unusual noise from the pump housing — should be replaced promptly to protect the engine and maintain uninterrupted operation on site.
