The 708-3S-00513 and 708-3S-00422 hydraulic pump assemblies are precision-engineered spare parts for Komatsu PC35MR-2 and PC40MR mini excavators. As the heart of the excavator's hydraulic system, these pumps deliver high-efficiency power transfer for critical operations including boom movement, arm control, bucket operation, and swing functions.

Built to OEM quality standards, this hydraulic pump features a compact yet powerful design, ensuring stable output pressure, energy efficiency, and reduced system noise. Whether for repair or replacement, it provides excellent compatibility and long-term reliability for light and medium-duty excavation work.

Each pump is fully tested, sealed, and packaged for international delivery by SPARKLING MACHINERY—a trusted supplier of excavator hydraulic parts for global customers.

The NACHI PVD-2B-40P-16G5-4191B hydraulic piston pump is a high-performance, precision-engineered main pump designed for mini excavators. Weighing approximately 25.5KG, this compact yet powerful pump is known for its excellent pressure stability, long service life, and strong durability under heavy-duty operations.

Crafted by NACHI, a globally trusted name in hydraulic technology, this piston-type variable displacement pump delivers smooth and efficient hydraulic flow, making it ideal for mini excavators that require precise control and consistent power.

   SPARKLING MACHINERY NEW R55W7 R55-7 11M8-42030 Radiator is a dedicated cooling system core component exclusively designed for R55W7 and R55-7 wheel excavators. As the heart of the excavators’ engine cooling system, it efficiently dissipates excess heat generated by the engine during heavy-duty operations—such as urban construction, small-scale digging, and site material handling—by transferring heat from coolant to the surrounding air. This function is critical for maintaining the engine’s optimal operating temperature (82–95°C), preventing overheating that could cause power loss, component warping, or irreversible engine damage.

   Engineered to match original equipment performance standards, it maintains high heat dissipation efficiency even under harsh working conditions, including high ambient temperatures (up to 45°C), continuous excavator vibration, and exposure to dust, debris, or rain. It resists coolant leakage and core corrosion, avoiding cooling system failures that lead to unplanned downtime or costly repairs. Backed by strict performance verification, it guarantees reliable heat management to support uninterrupted operation of R55W7/R55-7 wheel excavators.

The SEM Radiator 539‑1100 is a durable cooling system designed for SEM and Caterpillar machinery. Precisely engineered by Cat, this radiator maintains optimal engine temperature under heavy-duty conditions. Featuring premium materials and OEM-grade construction, it delivers enhanced corrosion resistance and long-term reliability—backed by Cat’s global parts support network
