SPARKLING MEGA 500-V TIER-II Pilot Pump – Precision Excavator Part

The 401-00423 hydraulic pilot pump, also known as the steering pump or pilot pressure pump, is a key component of the MEGA 500-V TIER-II wheel loader’s hydraulic system. With a robust 45kg build, this high-performance pump ensures precise pilot control, smooth steering assistance, and reliable hydraulic pressure for various operations.

Designed to OEM standards, this pump is built with reinforced cast iron housing, high-efficiency rotors, and hardened shafts, offering excellent resistance to wear, pressure fatigue, and oil contamination. It’s an ideal replacement for the original Doosan/Daewoo system pump and fully compatible with heavy-duty operation demands.

   SPARKLING MACHINERY NEW HB205 HB215 PC200 PC210 PC220 PC240 PC290 723-40-94501 Relief Valve is a dedicated hydraulic pressure protection component for Komatsu HB205, HB215, PC200, PC210, PC220, PC240, and PC290 crawler excavators (widely used in construction, mining, and infrastructure projects). As the "hydraulic safety barrier", it automatically relieves excess pressure when it exceeds the set threshold—protecting pumps, cylinders, and hoses from damage during high-intensity tasks like digging, rock breaking, and heavy lifting, while ensuring stable system operation.
   Meeting Komatsu OEM standards (part no. 723-40-94501), it maintains a precise pressure range of 28-32 MPa, endures -30°C to 95°C temperatures, resists hydraulic oil corrosion and vibration, and ensures instant pressure relief. Strict testing guarantees seamless compatibility with the seven Komatsu models and long-term hydraulic system safety.

   SPARKLING MACHINERY NEW EC460B EC460C EC460CHR EC480D EC480DHR 14609486 Seal Kit is a dedicated, heavy-duty sealing solution exclusively designed for VOLVO EC460B, EC460C, EC460CHR, EC480D, and EC480DHR crawler excavators—high-performance equipment critical for large-scale mining, heavy construction, and rugged infrastructure projects (e.g., rock quarries, tunnel excavation). As a core protective component for the excavators’ high-pressure hydraulic systems, it covers key areas including hydraulic cylinder rods, high-pressure valve connections, and pump interfaces, forming robust leakproof barriers. This function is vital for maintaining stable hydraulic pressure, ensuring smooth and responsive operation of ultra-heavy-load mechanisms (boom lifting, arm digging, bucket crushing), and preventing dust, gravel, 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 extreme tasks like hard rock breaking, bulk ore loading, and deep foundation excavation.

   Engineered to meet VOLVO’s original equipment standards, the seal kit maintains reliable sealing performance even under harsh conditions: high hydraulic pressure (up to 42 MPa), extreme temperature fluctuations (-25°C to 110°C), and continuous heavy-duty vibration from rugged terrain. It resists oil aging and abrasion, providing long-lasting protection for the hydraulic systems of EC460B/EC460C/EC460CHR/EC480D/EC480DHR models. Backed by strict performance verification, it guarantees uninterrupted sealing support for these VOLVO heavy excavators.
