Built for high-performance, this pump guarantees powerful flow, high efficiency, and exceptional durability even under extreme excavation workloads.

🔧 Key Features:

• Original quality fitment for Hyundai’s large crawler excavators

• Ensures precise pressure regulation and smooth hydraulic operation

• Manufactured with high-grade wear-resistant components

• Rigorously tested for flow rate, pressure endurance, and temperature resilience

   SPARKLING MACHINERY NEW EC140 EC150 EC210 14529303 Valve is a premium China-made hydraulic control component specifically engineered for EC140, EC150, and EC210 excavators. As a critical part of the hydraulic system, it regulates fluid flow, pressure, and direction to control the operation of hydraulic actuators such as booms, arms, and buckets, ensuring precise and responsive machinery movement in construction, mining, and earthmoving applications.​
   Designed to original equipment standards, it maintains stable hydraulic control and efficient energy transfer even under continuous high-pressure operation. With optimized valve spool design for minimal pressure loss and enhanced sealing performance, it adapts seamlessly to harsh working environments, from dusty job sites to wet conditions. Backed by strict quality verification, it guarantees consistent performance to support uninterrupted machinery operation.

   SPARKLING MACHINERY NEW ED150 140SR ED195-8 SK140SRLC YM30P01007F1 Coupling is a dedicated power transmission component for Kobelco ED150, 140SR, ED195-8, and SK140SRLC crawler excavators (widely used in construction, municipal engineering, and medium-scale demolition). As a core link in the excavator’s drive system, it connects the engine to hydraulic pumps or other rotating components—transmitting torque smoothly while absorbing vibration and compensating for minor alignment errors, ensuring stable power transfer during tasks like digging, breaking, and material loading.
   Meeting Kobelco OEM standards (part no. YM30P01007F1), it endures high torque loads (up to 500 N·m), -30°C to 90°C temperatures, resists wear and oil corrosion, and maintains consistent transmission performance. Strict testing guarantees seamless compatibility with the four Kobelco models and long-term reliable power linkage.

   SPARKLING MACHINERY NEW EC160B EC180B EW160B 14589157 Seal Kit is a dedicated, all-in-one sealing solution exclusively designed for VOLVO EC160B, EC180B excavators, and EW160B wheeled excavators—versatile equipment widely used in construction, municipal maintenance, and light mining projects. As a core protective component for the machinery’s hydraulic systems, it covers critical areas including hydraulic cylinder rods, valve connections, and pump interfaces, forming reliable leakproof barriers. This function is essential for maintaining stable hydraulic pressure, ensuring smooth and responsive operation of core mechanisms (boom lifting, arm digging, bucket tilting), and preventing dust, debris, or moisture from contaminating internal hydraulic parts. It directly reduces the risk of hydraulic system failures, avoids unplanned downtime, and eliminates costly repairs caused by oil leaks during tasks like trench digging, material loading, and road maintenance.

   Engineered to meet VOLVO’s original equipment standards, the seal kit maintains consistent sealing reliability even under harsh conditions: high hydraulic pressure (up to 35 MPa), extreme temperature fluctuations (-25°C to 105°C), and continuous machinery vibration. It resists oil aging and wear, providing long-lasting protection for the hydraulic systems of EC160B/EC180B/EW160B models. Backed by strict performance verification, it guarantees uninterrupted sealing support for these VOLVO machines.
