Original Cummins engine spare parts water pump C5465815

A core advantage of the C5465815 water pump is its exceptional cooling efficiency, tailored to Cummins engines’ high-heat output. It features a precision-machined impeller with 8 curved blades that optimize coolant flow rate (up to 120 L/min at rated speed), ensuring uniform heat distribution across the engine block, cylinder head, and turbocharger. The pump’s volute design minimizes flow resistance, maintaining a consistent coolant pressure of 15-20 kPa—critical for preventing hotspots that lead to engine overheating or component warping. Even under full load (e.g., heavy hauling or continuous power generation), the pump sustains optimal coolant circulation, keeping the engine within the ideal operating temperature range (82-95°C). For operators, this efficiency reduces the risk of downtime caused by overheating and supports the engine’s maximum power output

Built to withstand the rigors of Cummins engine operation, the C5465815 water pump uses premium, OEM-grade materials. The pump housing is made of cast iron (HT250) with a corrosion-resistant enamel coating, offering high heat resistance (up to 180°C) and protection against coolant chemicals (e.g., antifreeze additives). The shaft is crafted from high-carbon steel (45#) with a chrome-plated surface (0.05mm thickness), reducing friction and wear on the sealed bearing—extending the pump’s service life to 150,000+ km. The bearing assembly uses double-row ball bearings rated for 5,000+ hours of continuous operation, ensuring smooth rotation even in high-vibration environments. Rigorous durability tests (1,000-hour thermal cycling, 500-hour salt spray exposure) confirm the pump maintains functionality for 5+ years, outperforming aftermarket alternatives that often fail within 2-3 years

The C5465815 water pump integrates a multi-layer sealing system to eliminate coolant leaks—a common issue that damages engine components and reduces cooling efficiency. It features a carbon-graphite mechanical seal with a nitrile rubber secondary seal, creating a tight barrier between the shaft and housing that resists wear and chemical degradation. The seal’s spring-loaded design maintains constant pressure against the shaft, compensating for minor wear and preventing leaks even as the pump ages. Additionally, the pump’s mounting gasket (included) is made of high-temperature-resistant silicone rubber, ensuring a leak-free seal between the pump and engine block. These sealing features reduce the risk of coolant loss by 95%, avoiding engine overheating and costly repairs to damaged belts, hoses, or electrical components

Designed for ease of use, the C5465815 water pump simplifies installation and maintenance for Cummins engine operators. It comes pre-assembled with the impeller, shaft, bearing, and mounting gasket—eliminating the need for separate parts sourcing or on-site assembly. The pump’s pulley is pre-aligned with the shaft, ensuring proper belt fitment without additional adjustment. Installation requires only standard tools (socket wrench, torque wrench) and follows Cummins’ recommended procedures, taking 2-3 hours for a skilled technician. A detailed OEM instruction manual (with torque specifications: 40-45 N·m for mounting bolts) is included, guiding proper fitment and coolant refilling. For maintenance, the pump’s sealed bearing requires no lubrication, reducing upkeep tasks. This user-friendly design minimizes engine downtime, ensuring Cummins-powered equipment returns to service faster for time-sensitive operations
