The 705-12-35250 Gear Pump Assembly is a critical hydraulic component designed for KOMATSU HM400-3R Articulated Dump Trucks. This gear pump plays a vital role in ensuring smooth and efficient hydraulic flow for critical systems, including steering, braking, and body lifting functions.

Manufactured with high-precision machining and quality-tested materials, the 7051235250 gear pump offers excellent reliability, extended service life, and consistent performance under extreme working conditions. Whether you're replacing a worn-out unit or conducting scheduled maintenance, SPARKLING MACHINERY's aftermarket gear pump ensures optimal compatibility and long-term value.

   SPARKLING MACHINERY NEW EC240B EC240C FC2924C 14531594 Hydraulic Pump is a premium China-made power component specifically engineered for EC240B, EC240C, and FC2924C excavators. As the core of the hydraulic system, it converts mechanical energy into hydraulic pressure, driving critical operations such as boom lifting, arm articulation, and bucket movement through controlled fluid flow. This ensures efficient power transmission and responsive machinery performance in construction, mining, and heavy-duty earthmoving applications.​
   Designed to original equipment standards, it maintains stable pressure output and consistent flow rates even under continuous high-load operation. With optimized internal design for minimal energy loss and enhanced wear resistance, it adapts seamlessly to harsh working environments, from dusty job sites to high-temperature conditions. Backed by strict quality verification, it guarantees reliable performance to support uninterrupted machinery operation.

   SPARKLING MACHINERY NEW 2420-1125A Valve; By-Pass 4.5B is a dedicated hydraulic pressure regulation component for Doosan excavators (widely used in construction, mining, and municipal engineering). As the "hydraulic pressure buffer", it diverts excess hydraulic oil back to the tank when system pressure reaches 4.5B (bar) — preventing overpressure damage to pumps, valves, and cylinders during tasks like digging, lifting, and rock breaking, while ensuring stable oil flow for critical operations.
   Meeting Doosan OEM standards (part no. 2420-1125A), it maintains precise pressure control (4.5B set threshold), endures -30°C to 95°C temperatures, resists hydraulic oil corrosion and vibration, and ensures leak-free performance. Strict testing guarantees seamless compatibility with applicable Doosan models and long-term hydraulic system safety.

   SPARKLING MACHINERY NEW 1BQ8-40030/11Q8-41320 Radiator is a core cooling component exclusively for Hyundai R300-9 excavators (heavy-duty construction/mining use). It efficiently dissipates engine heat to maintain optimal operating temperatures, critical for heavy-load durability. 
   Meeting Hyundai OEM standards (1BQ8-40030/11Q8-41320), it resists -30°C to 120°C temps, dust, and corrosion, ensuring seamless compatibility and long-term reliable thermal management performance.
