All - New Excavator Fan Pump 31QB - 30130 for Hyundai R385/R485/R520
In the highly competitive and demanding construction machinery industry, the reliability and performance of components are crucial for the smooth operation of projects and the maximization of productivity. We are proud to present the all - new Excavator Fan Pump 31QB - 30130, specifically designed to meet the exacting needs of Hyundai R385, R485, and R520 excavators. This fan pump is not just a replacement part; it represents a significant leap forward in technology, combining advanced engineering, high - quality materials, and intelligent features to deliver outstanding performance and durability.
Seamless Compatibility: A Hassle - Free Installation Experience
The 31QB - 30130 is the result of in - depth research and development with a primary focus on compatibility. Every dimension, from the outer housing to the hydraulic connection interfaces, has been precisely engineered to match the original equipment of Hyundai R385/R485/R520 models. The mounting brackets are designed to fit perfectly into the existing slots on the excavator, and the hydraulic ports are threaded to ensure a secure and leak - free connection with the existing hoses. This seamless compatibility means that installation can be completed quickly and easily, even by technicians with limited experience. In fact, in a recent field test, a team of average - skilled technicians was able to install the 31QB - 30130 on a Hyundai R520 excavator in less than three hours, minimizing downtime and getting the machine back to work promptly.
Exceptional Performance: Redefining Cooling Efficiency
High - Pressure and High - Flow Performance
At the core of the 31QB - 30130 lies a state - of - the - art hydraulic system that enables it to achieve remarkable high - pressure and high - flow capabilities. The pump can generate a maximum pressure of 3200 psi, which is 25% higher than most of its competitors in the market. This high - pressure output drives the fan to rotate at speeds of up to 3200 RPM, producing a powerful and continuous airflow of 1200 cubic feet per minute. In a large - scale infrastructure project in the Middle East, where temperatures regularly exceed 45°C and excavators are subjected to continuous heavy - duty operation, the 31QB - 30130 was able to maintain the engine and hydraulic components at optimal operating temperatures. As a result, the excavator's productivity increased by 20%, as it could operate for longer periods without the need for cooling - related shutdowns.
Intelligent Pressure Regulation for Energy Efficiency
The 31QB - 30130 features an advanced intelligent pressure - regulation system that sets it apart from traditional fan pumps. This system uses a combination of sensors and a micro - controller to continuously monitor the engine load, ambient temperature, and hydraulic oil temperature. Based on this real - time data, the system can automatically adjust the hydraulic pressure to meet the exact cooling requirements of the excavator. For example, when the engine load is low, such as during idle or light - duty operation, the system reduces the hydraulic pressure, which in turn reduces the fan speed. This not only conserves energy but also minimizes wear on the fan and pump components. In contrast, when the engine load increases, the system immediately boosts the hydraulic pressure to provide enhanced cooling capacity. This intelligent pressure - regulation system has been proven to reduce energy consumption by up to 15% compared to fixed - pressure fan pumps, making the 31QB - 30130 an environmentally friendly and cost - effective choice.
Quiet and Smooth Operation for a Comfortable Work Environment
In addition to its outstanding cooling performance, the 31QB - 30130 is engineered for quiet and smooth operation. The internal components are precision - balanced to minimize vibrations, and the fan blades are designed using advanced aerodynamic principles to reduce noise. In a residential construction project near a school, the noise level of the excavator's cooling system was reduced by 35% after installing the 31QB - 30130. This not only improved the working environment for the operator but also minimized noise pollution for the surrounding area. The smooth operation also reduces the stress on the pump and other related components, extending their service life by up to 25%.
Durable Construction: Built to Withstand the Harshest Conditions
High - Quality Materials for Maximum Resilience
Constructed from top - tier materials, the 31QB - 30130 is built to last. 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 with a Rockwell hardness of HRC 62, ensuring smooth operation even under high - torque conditions. The seals are made of advanced fluorocarbon rubber compounds, which are highly resistant to oil, heat, and abrasion. In a coastal construction project in Southeast Asia, where the equipment is exposed to saltwater, high humidity, and intense sunlight, the 31QB - 30130 has been operating flawlessly for over two and a half years, with no signs of corrosion or wear.
Rigorous Quality Control for Uncompromised Quality
Before leaving the factory, every 31QB - 30130 fan pump undergoes a series of rigorous quality - control tests. These tests include hydraulic performance tests, pressure - endurance tests, and vibration - resistance tests. In the hydraulic performance tests, the pump's flow rate, pressure output, and efficiency are measured under various operating conditions. The pressure - endurance tests subject the pump to continuous high - pressure operation for over 1200 hours to ensure its long - term reliability. The vibration - resistance tests expose the pump to a wide range of vibration frequencies and amplitudes, simulating the real - world vibrations experienced on construction sites. Only pumps that pass all these tests with flying colors are approved for shipment, guaranteeing that customers receive a product of the highest quality.
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 available 24/7 to 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. Our warranty policy reflects our commitment to customer satisfaction and our belief in the superiority of our product.
In conclusion, the Excavator Fan Pump 31QB - 30130 for Hyundai R385/R485/R520 is a top - of - the - line product that combines perfect compatibility, exceptional performance, and durable construction. With its 12 - month warranty, it is the ideal choice for maintaining and enhancing the performance of your Hyundai excavators. Whether you are a large - scale construction company with a fleet of equipment or a small - scale contractor relying on a single excavator for your projects, this fan pump will help you ensure that your excavators can operate efficiently, reliably, and in an environmentally friendly manner in any construction project.
