SPARKLING Hyundai Excavator Pump – Precision & Reliability

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 31Q8-10011 Main Pump is a core hydraulic power component exclusively for Hyundai R480LC-9S excavators (super heavy-duty construction/mining use). It converts mechanical energy to stable high-pressure hydraulic oil, driving boom, arm, and bucket operations for extreme heavy-load tasks. 
   Meeting Hyundai OEM standards (31Q8-10011), it resists -30°C to 100°C temps, ultra-high pressure, and wear, guaranteeing seamless compatibility and long-term reliable hydraulic performance.

   SPARKLING MACHINERY NEW EC120D EC135B EC160E EC210B 980102 O-Ring is a dedicated sealing component exclusively designed for VOLVO EC120D, EC135B, EC160E, and EC210B excavators—essential equipment in construction, mining, and municipal infrastructure projects. As a core part of the excavators’ hydraulic, fuel, and coolant systems, it forms tight, leakproof seals between mating components (e.g., hydraulic valve joints, fuel line connections, and coolant hose interfaces). This function is critical for maintaining stable system pressure, preventing leakage of hydraulic oil, fuel, or coolant, and blocking dust or debris from entering internal mechanisms. It directly reduces the risk of system failures, avoids unplanned downtime, and eliminates costly repairs caused by leaks during high-intensity operations like digging, material loading, or road maintenance.

   Engineered to match VOLVO’s original equipment standards, the O-ring maintains reliable sealing performance even under harsh conditions: high pressure (up to 32 MPa), extreme temperature fluctuations (-30°C to 110°C), and continuous excavator vibration. It resists fluid aging and material degradation, ensuring long-lasting protection for the excavators’ key systems. Backed by strict performance verification, it guarantees consistent sealing support for EC120D/EC135B/EC160E/EC210B excavators.

   SPARKLING MACHINERY NEW E360LC DZ111136 Suction Control Valve is a dedicated fuel/hydraulic regulation component for John Deere E360LC crawler excavators (widely used in heavy construction, mining, and large-scale infrastructure projects). As the "fluid intake regulator", it precisely controls the flow of fuel or hydraulic fluid into critical systems (e.g., engine fuel pumps or hydraulic main pumps)—ensuring stable pressure and flow during high-intensity tasks like heavy digging, rock breaking, and boom lifting, while preventing system overload or insufficient fluid supply.
   Meeting John Deere OEM standards (part no. DZ111136), it endures 28 MPa working pressure, -30°C to 95°C temperatures, resists fluid corrosion and vibration, and maintains consistent control performance. Strict testing guarantees seamless compatibility with John Deere E360LC and long-term system operational reliability.
