The OE51169 Water Pump is specifically engineered for Perkins engines, with core compatibility for mainstream models including:

• Perkins 400 Series (404D-22TA, 403D-17)
• Perkins 1100 Series (1104C-44T, 1103A-33TG1)

This high-flow coolant pump is extensively utilized in various industrial applications:

• Small to medium-sized generator sets (10-100kVA)
• Construction machinery (compact loaders, micro excavators)
• Agricultural equipment (tractors, seed drills)
• Industrial auxiliary systems

As the core power component of the engine cooling system, the OE51169 water pump drives the impeller to rotate at high speed via belt transmission. It pressurizes and circulates low-temperature coolant from the radiator to the engine block and cylinder head water jackets, absorbing the high heat generated by combustion.

The heated coolant is returned to the radiator for cooling, forming a closed-loop thermal dissipation circuit. During operation, it precisely regulates engine operating temperature, maintaining the optimal range of 80-95°C to prevent failures such as piston seizure or cylinder block deformation caused by overheating.

When original equipment water pumps exhibit issues like leakage, impeller wear, or bearing noise, the OE51169 serves as an original equipment-grade replacement. This high-flow coolant pump with gaskets swiftly restores cooling system efficiency to ensure long-term, stable engine operation.
