Water Pump 20744939 D13 For Vol vo Engine D12 D16

The pump body adopts precision cast aluminum alloy integrated casting, lightweight structure, excellent heat dissipation, shock resistance and corrosion resistance. Adapted to long-term heavy-load operation of excavators and heavy trucks, effectively resisting vibration deformation under harsh working conditions.

Equipped with high-performance composite mechanical water seal and high-speed anti-fatigue bearing. The impeller assembly undergoes strict dynamic balance testing to effectively prevent coolant leakage and bearing ablation, avoid engine overheating shutdown caused by water pump failure.

CNC precision machining for all mounting flanges, water flow passages and bolt hole positions. Direct replacement without modification, perfectly matched Vol vo D13 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 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 D13 engine and extend overall service life of equipment.
