Water Pump 6261-61-1204 SAA6D140E For Komatsu Engine

The pump body adopts high-strength cast iron integral casting technology, strong shock resistance and corrosion resistance. It adapts to harsh mining and construction site working conditions, effectively avoiding pump body cracking and deformation under long-term heavy vibration.

Equipped with built-in transmission gear, matched with heavy-duty anti-fatigue bearing and multi-layer composite mechanical water seal. The impeller assembly undergoes strict dynamic balance testing, effectively preventing coolant leakage and bearing burnout, avoiding engine overheating shutdown caused by water pump failure.

CNC precision machining for all installation flanges, water inlet/outlet passages and bolt hole positions. Direct replacement without modification, perfectly matching Komatsu SAA6D140E engine, stable assembly and reliable sealing performance.

Streamlined large-flow impeller designed according to original factory parameters, providing stable coolant flow and pressure. Guarantee sufficient cooling for cylinder block and cylinder head under full-load operation, reduce high-temperature abrasion and prevent cylinder scuffing and power drop.

Replace aging original water pump to restore standard cooling circulation, solve engine overheating, boiling water, power loss and excessive fuel consumption. Maintain normal operating temperature of SAA6D140E engine and extend overall service life of equipment.
