All - New Excavator Fan Pump 31QB - 30130 for Hyundai R385/R485/R520
In the challenging and fast - paced construction machinery field, the reliable operation of every component is crucial. Presenting the all - new Excavator Fan Pump 31QB - 30130, specially designed for Hyundai R385, R485, and R520 excavators. This fan pump is set to bring a new level of performance, durability, and compatibility, revolutionizing the way these excavators function.
Seamless Compatibility for Hassle - Free Installation
The 31QB - 30130 fan pump is a product of precise engineering. Its physical design, including the outer shape and internal structure, is crafted to perfectly match the original equipment of Hyundai R385/R485/R520 models. The hydraulic connection parts are designed with high - precision, allowing for easy connection to the existing hydraulic system of the excavators. This means no need for complex modifications or custom - made parts during installation. Once installed, it becomes an integrated part of the excavator, working in harmony with other components. Whether it's a busy urban construction site or a remote mining area, you can count on the smooth integration and stable operation of the 31QB - 30130.
Exceptional Performance for Optimal Cooling
High - Pressure and High - Flow Performance
Equipped with advanced hydraulic components, the 31QB - 30130 fan pump can generate high - pressure and high - flow output. It provides a stable and strong pressure, driving the fan to produce a powerful and continuous airflow. This is essential for effective heat dissipation, especially when the excavator's engine and other key components are under heavy loads. For example, during long - term digging in high - temperature environments or continuous operation in dusty conditions, the 31QB - 30130 can quickly cool down these components. By maintaining the optimal operating temperature, it prevents overheating - related performance degradation and equipment damage, thus extending the service life of the excavator.
Intelligent Pressure Regulation
The fan pump features an intelligent pressure - regulation system. This system can sense the real - time cooling needs of the excavator according to factors such as engine load and ambient temperature. When the engine load is high, the system automatically increases the hydraulic pressure to boost the fan speed and enhance cooling capacity. When the load is low, it reduces the pressure to save energy and reduce wear on the fan and pump. This intelligent regulation not only improves the excavator's performance but also helps in long - term cost - saving by reducing energy consumption and maintenance frequency.
Quiet and Smooth Operation
In addition to its excellent cooling performance, the 31QB - 30130 is designed for quiet and smooth operation. The internal components are carefully balanced and optimized to minimize noise and vibration. This creates a more comfortable working environment for the operator. Excessive noise and vibration can cause fatigue and distraction, affecting work efficiency and safety. The smooth operation also benefits the equipment, reducing the stress on components and prolonging their service life.
Durable Construction for Long - Term Reliability
High - Quality Materials
Constructed from high - grade materials, the 31QB - 30130 fan pump is built to last. The pump housing is made of high - strength alloy steel, which offers great resistance to impact, corrosion, and high - pressure hydraulic forces. The internal gears are made of hardened steel, capable of withstanding high - torque forces. The seals are made of advanced rubber compounds, which are resistant to oil, heat, and abrasion. These high - quality materials ensure the long - term reliability and stable performance of the fan pump, making it suitable for the harshest construction conditions.
Rigorous Quality Control
Before leaving the factory, every 31QB - 30130 fan pump undergoes a series of strict quality - control tests. Hydraulic performance tests are carried out to measure the flow rate, pressure output, and efficiency accurately. Pressure - endurance tests simulate long - term operation under high - pressure conditions to test the durability of the pump. Vibration - resistance tests expose the pump to different vibration frequencies and amplitudes to ensure its stability in vibrating environments. Only pumps that pass all these tests are approved for shipment, guaranteeing a high - quality product for customers.
12 - Month Warranty: Your Peace of Mind
We have full confidence in the quality of the Excavator Fan Pump 31QB - 30130, so we offer a 12 - month warranty. During this period, if you encounter any quality - related problems, our professional customer service team will provide prompt technical support. We will arrange for free replacement or repair if necessary. Our warranty policy reflects our commitment to customer satisfaction and the high - quality standard of our product.
