MADE IN CHINA SPARKLING MACHINERY NEW 3078150 SENSOR
SPARKLING MACHINERY NEW 3078150 Sensor is a dedicated precision detection component tailored for compatible heavy-duty construction machinery, such as excavators and loaders. As a core part of the machinery’s operational monitoring system, it real-time collects critical data—including hydraulic pressure, engine temperature, or component position—and transmits accurate signals to the machinery’s control unit. This function is essential for enabling the control system to adjust operations dynamically during heavy-duty tasks like digging, lifting, and grading, directly ensuring stable machinery performance, preventing overloading or overheating, and reducing the risk of unexpected component damage.
Engineered to match original equipment performance standards, it maintains high signal accuracy and stable operation even under harsh working conditions, including continuous vibration, dust exposure, temperature fluctuations (-30°C to 80°C), and hydraulic oil contamination. It resists signal interference and mechanical wear, avoiding data errors or transmission failures that could lead to operational delays or safety hazards. Backed by strict performance verification, it guarantees reliable data feedback to support uninterrupted operation of compatible heavy-duty machinery.

VOLVO EXCAVATOR PARTS MADE IN CHINA NEW EC220D EC250D EC250E EC300D 14600640 SEAL KIT SPARKLING MACHINERY
SPARKLING MACHINERY NEW EC240C EC250D EC250E EC290B EC300E 14596398 Seal Kit is a dedicated, all-in-one sealing solution exclusively designed for VOLVO EC240C, EC250D, EC250E, EC290B, and EC300E crawler excavators—heavy-duty equipment critical for large-scale construction, mining, and infrastructure projects. As a core protective component for the excavators’ high-pressure hydraulic systems, it covers key areas including hydraulic cylinder rods, valve connections, and pump interfaces, forming robust leakproof barriers. This function is vital for maintaining stable hydraulic pressure, ensuring smooth and responsive operation of high-load mechanisms (boom lifting, arm digging, bucket tilting), 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 high-intensity tasks like rock breaking, bulk material loading, and deep 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 38 MPa), extreme temperature fluctuations (-25°C to 105°C), and continuous heavy-duty excavator vibration. It resists oil aging and wear, providing long-lasting protection for the hydraulic systems of EC240C/EC250D/EC250E/EC290B/EC300E models. Backed by strict performance verification, it guarantees uninterrupted sealing support for these VOLVO excavators.
