1. Heavy-Duty Cast Iron Housing

   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.

2. Integrated Drive Gear & High Precision Sealing Assembly

   Equipped with integrated 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.

3. 100% OEM Dimension Standard

   CNC precision machining for all installation flanges, water inlet/outlet passages and bolt hole positions. Direct replacement without modification, perfectly matching Komatsu 6D125-5 engine, stable assembly and reliable sealing performance.

4. Optimized Large-Flow Hydraulic Circulation Design

   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.

5. Stable Engine Temperature Control

   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 6D125-5 engine and extend overall service life of equipment.

Delivery: We support multiple reliable shipping methods, including SF Express, YTO, ZTO and EMS. All products pass strict hydraulic pressure and running test before delivery, anti-rust packaging, complete tracking information for global delivery.
