All - New Excavator Fan Pump 31QB - 30130 for Hyundai R385/R485/R520
In the highly competitive construction machinery market, where every component must meet the highest standards of performance and reliability, the new Excavator Fan Pump 31QB - 30130 for Hyundai R385/R485/R520 stands out as a remarkable innovation. Engineered with precision and built to last, this fan pump is set to transform the cooling systems of these heavy - duty excavators.
Unparalleled Compatibility for Effortless Setup
The 31QB - 30130 is a product of painstaking design work focused on seamless integration. Its physical structure, from the outer housing dimensions to the minutest internal parts, has been designed to be a perfect fit for Hyundai R385/R485/R520 models. The hydraulic connection points are not only easy to install but also ensure a secure and leak - free connection to the existing hydraulic pipelines. This means that construction teams can quickly swap out old pumps or install new ones without the need for complex tools or modifications. For example, in a large - scale road - building project, a crew was able to install the 31QB - 30130 in just a few hours, minimizing downtime and getting the excavator back to work promptly. Once installed, the pump becomes an integral part of the excavator's hydraulic system, working in harmony with other components to ensure stable and efficient operation.
Superior Performance for Maximum Cooling Efficiency
High - Pressure and High - Flow Performance
At the heart of the 31QB - 30130 lies a set of advanced hydraulic components that enable it to deliver outstanding high - pressure and high - flow performance. The pump can generate a consistent and powerful pressure output, which drives the fan to produce a strong and continuous airflow. In a mining operation in a hot and arid region, the excavator's engine and hydraulic components were constantly at risk of overheating due to the extreme working conditions. After installing the 31QB - 30130, the equipment was able to maintain optimal operating temperatures even during long - hours of continuous operation. This high - volume airflow effectively dissipates heat, preventing overheating - related performance degradation and equipment failures. By keeping the engine and other components cool, the 31QB - 30130 not only extends the lifespan of the excavator but also reduces maintenance costs significantly.
Intelligent Pressure Regulation
The fan pump features an intelligent pressure - regulation system that sets it apart from its competitors. This system can sense the real - time cooling requirements of the excavator based on various factors such as engine load, ambient temperature, and the type of work being performed. When the engine is under heavy load, for instance, during large - scale earth - moving tasks or when digging through hard rock, the pressure - regulation system automatically increases the hydraulic pressure. This drives the fan to rotate at a higher speed, providing enhanced cooling capacity. Conversely, when the load is lighter, the system reduces the pressure, conserving energy and minimizing wear on the fan and pump components. In a residential construction project where the excavator's workload varied throughout the day, the intelligent pressure - regulation system of the 31QB - 30130 ensured that the cooling system was always operating at the optimal level, saving energy and reducing the need for frequent maintenance.
Quiet and Smooth Operation
In addition to its excellent cooling performance, the 31QB - 30130 is engineered for quiet and smooth operation. The internal components are carefully balanced and optimized to minimize noise and vibrations. In a construction site located near a residential area, the noise generated by the excavator's cooling system was a major concern. After installing the 31QB - 30130, the noise level was significantly reduced, creating a more comfortable working environment for the operator and minimizing noise pollution for the surrounding community. The smooth operation also reduces the stress on the pump and other related components, extending their service life and reducing the frequency of component replacements.
Durable Construction for Long - Term Reliability
High - Quality Materials
Constructed from top - tier materials, the 31QB - 30130 is built to withstand the harshest conditions of the construction industry. The pump housing is made of high - strength alloy steel, which offers excellent resistance to impacts, corrosion, and the high - pressure hydraulic forces that are common in construction machinery. The internal gears are crafted from hardened steel, capable of withstanding high - torque forces without significant wear, ensuring smooth and reliable operation even under the most demanding workloads. The seals are made of advanced rubber compounds that are highly resistant to oil, heat, and abrasion. In a coastal construction project where the equipment was exposed to saltwater and high humidity, the 31QB - 30130's corrosion - resistant materials and robust construction ensured its reliable performance over an extended period.
Rigorous Quality Control
Before leaving the factory, every 31QB - 30130 fan pump undergoes a series of rigorous quality - control tests. Hydraulic performance tests are conducted to measure the pump's flow rate, pressure output, and efficiency with great precision. Pressure - endurance tests simulate long - term operation under high - pressure conditions to test the pump's durability. Vibration - resistance tests expose the pump to various vibration frequencies and amplitudes to ensure its stability in vibrating environments. Only pumps that pass all these tests with flying colors are approved for shipment. This strict quality - control process guarantees that customers receive a product of the highest quality, giving them peace of mind that their investment is well - protected.
12 - Month Warranty: Your Assurance of Quality
We have complete confidence in the quality and reliability of the 31QB - 30130, which is why we offer a comprehensive 12 - month warranty. During this period, if you encounter any quality - related issues, our dedicated customer service team is just a phone call or an email away.
