SPARKLING 31QB-10030 Main Pump – Durable Excavator Hydraulic Component

The 31QB-10037 / 31QB-10030 Hydraulic Main Pump Assembly is an essential component for delivering stable hydraulic power to your Hyundai crawler excavators. 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 EC200B EC210B EC210C EC200D VOE14552686 Swing Motor - a premium China-made hydraulic component, is specifically engineered for EC200B, EC210B, EC210C, and EC200D excavators. As the core rotational power unit, it enables smooth and precise 360° slewing of the upper structure, critical for efficient operation in construction, mining, and earthmoving tasks.

   Crafted from high-strength alloy materials with precision-machined internal components, this swing motor withstands high pressure and heavy loads while maintaining stable performance. Equipped with advanced hydraulic control technology and multi-layer sealing systems, it resists leakage, dust, and water intrusion, adapting to harsh working environments. Backed by strict quality testing and professional support, it guarantees reliable rotational power, minimizing downtime and maximizing equipment productivity.

   SPARKLING MACHINERY NEW R300LC9A R300LC9S 31Q8-10030 Main Pump is a core hydraulic power component for 2 Hyundai excavator models (heavy-duty construction/mining use). It converts mechanical energy to stable high-pressure hydraulic oil, driving boom, arm, and bucket operations. 
   Meeting Hyundai OEM standards (31Q8-10030), it resists -30°C to 100°C temps, high pressure, and wear, guaranteeing seamless compatibility and long-term reliable hydraulic performance.

   SPARKLING MACHINERY NEW R210LC9 R210LC9BC R210LC9BH R220LC9A 31Q6-01290 Cover Assy is a dedicated protective component for Hyundai R210LC9, R210LC9BC, R210LC9BH, and R220LC9A crawler excavators (widely used in construction, mining, and infrastructure projects). As a core shielding part for key excavator systems (e.g., hydraulic pumps, engine components), it blocks dust, debris, and moisture from entering internal mechanisms—ensuring undisturbed operation during high-intensity tasks like heavy digging, rock breaking, and bulk material loading.
   Meeting Hyundai OEM standards (part no. 31Q6-01290), it endures -30°C to 90°C temperatures, resists impact and corrosion, and maintains structural stability. Strict testing guarantees seamless compatibility with the four Hyundai models and long-term protection for critical equipment systems.
