All - New Excavator Fan Pump 31QB - 30130 for Hyundai R385/R485/R520
In the fast - paced and challenging construction machinery domain, where equipment breakdowns can lead to significant project delays and increased costs, having reliable components is essential. We are excited to present the all - new Excavator Fan Pump 31QB - 30130, designed specifically for Hyundai R385, R485, and R520 excavators. This fan pump is not just a replacement part; it's a technological advancement that offers enhanced performance, durability, and compatibility.
Seamless Compatibility for Hassle - Free Installation
The 31QB - 30130 is the result of meticulous engineering. Every dimension, from the mounting holes to the hydraulic connection ports, is precisely designed to match the original equipment of Hyundai R385/R485/R520 models. This means that installation is straightforward, with no need for complex modifications or custom - made adapters. For example, a construction company that recently upgraded their excavators' fan pumps found that the 31QB - 30130 could be installed within a few hours, even by a relatively inexperienced technician. Once installed, the pump integrates perfectly with the existing hydraulic system, ensuring stable operation. Whether you're operating in a busy urban construction site with tight schedules or a remote mining area with limited resources, the 31QB - 30130's compatibility ensures that your excavator can get back to work quickly.
Exceptional Performance for Optimal Cooling
High - Pressure and High - Flow Powerhouse
Equipped with advanced hydraulic technology, the 31QB - 30130 can generate a high - pressure output that drives the fan to produce a powerful and continuous airflow. In a large - scale infrastructure project in a hot desert region, the excavator's engine and hydraulic components were constantly under extreme heat stress. After installing the 31QB - 30130, the equipment was able to maintain its optimal operating temperature, even during continuous operation for long hours. This high - volume airflow is crucial for efficient heat dissipation, preventing overheating - related performance degradation and equipment failures. By keeping the engine and other components cool, the 31QB - 30130 extends the lifespan of the excavator and reduces maintenance costs.
Intelligent Pressure Regulation
The fan pump features an intelligent pressure - regulation system. This system can sense the real - time cooling needs of the excavator based on factors such as engine load, ambient temperature, and the type of work being done. For instance, when an excavator is engaged in heavy - duty digging in a quarry, the engine load increases, and the 31QB - 30130 automatically adjusts the hydraulic pressure to drive the fan 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. This intelligent regulation not only improves the overall performance of the excavator but also contributes to long - term cost - savings.
Quiet and Smooth Operation
In addition to its cooling performance, the 31QB - 30130 is designed for quiet and smooth operation. The internal components are carefully balanced and optimized to minimize noise and vibrations. In a residential construction project, the noise level was a major concern. The 31QB - 30130 significantly reduced the noise generated by the excavator's cooling system, creating a more comfortable working environment for the operator and reducing noise pollution for the surrounding area. The smooth operation also reduces the stress on the pump and other related components, extending their service life.
Durable Construction for Long - Term Reliability
High - Quality Materials
Constructed from top - grade materials, the 31QB - 30130 is built to last. The pump housing is made of high - strength alloy steel, which can withstand impacts, resist corrosion, and endure the high - pressure hydraulic forces present in construction machinery. The internal gears are crafted from hardened steel, ensuring smooth operation even under high - torque conditions. The seals are made of advanced rubber compounds that are 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 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 flow rate, pressure output, and efficiency of the pump. Pressure - endurance tests simulate long - term operation under high - pressure conditions to check the pump's durability. Vibration - resistance tests expose the pump to various vibration frequencies and amplitudes to ensure its stability in real - world operating environments. Only pumps that pass all these tests are approved for shipment, guaranteeing that customers receive a high - quality product.
12 - Month Warranty: Your Assurance of Quality
We have full confidence in the quality and reliability of the 31QB - 30130, which is why we offer a comprehensive 12 - month warranty. If you encounter any quality - related issues during this period, our dedicated customer service team will provide prompt technical support. We will arrange for a free replacement or repair, ensuring that you can continue to use your excavator with peace of mind.
