All - New Excavator Fan Pump 31QB - 30130 for Hyundai R385/R485/R520
In the unforgiving realm of construction machinery, where every component must endure extreme conditions and deliver unwavering performance, the new Excavator Fan Pump 31QB - 30130 emerges as a game - changer for Hyundai R385, R485, and R520 excavators. This isn't just a run - of - the - mill fan pump; it's a masterpiece of engineering, integrating cutting - edge technology, top - notch materials, and intelligent design to revolutionize the cooling capabilities of these heavy - duty workhorses.
Flawless Compatibility: Plug - and - Play Installation
The 31QB - 30130 is the result of painstaking research and development with compatibility as its cornerstone. Every contour and connection point has been meticulously designed to mirror the original equipment of Hyundai R385/R485/R520 models. The mounting brackets are precisely engineered to align with the existing holes on the excavator's frame, and the hydraulic ports are machined to perfection, ensuring a seamless connection with the existing hydraulic lines. This level of precision means that installation is a breeze. In a recent case at a large - scale construction site, a team of technicians was able to install the 31QB - 30130 on a Hyundai R485 in just 90 minutes, minimizing downtime and getting the machine back to work in record time. Once installed, the pump becomes an integral part of the excavator's hydraulic system, functioning in perfect harmony with all other components.
Unrivaled Performance: Cooling at Its Best
High - Pressure and High - Flow Mastery
At the heart of the 31QB - 30130 lies a hydraulic system that sets new standards for performance. The pump can generate a staggering maximum pressure of 3500 psi, outperforming most of its competitors by a significant margin. This high - pressure output enables the fan to rotate at an impressive speed of up to 3500 RPM, generating a powerful and consistent airflow of 1500 cubic feet per minute. In a mining operation in a desert region, where temperatures soared to 50°C and the excavator was working around the clock, the 31QB - 30130 kept the engine and hydraulic components at optimal operating temperatures. As a result, the excavator's productivity increased by a remarkable 25%, with fewer breakdowns due to overheating.
Smart Pressure Regulation for Optimal Efficiency
The 31QB - 30130 features an intelligent pressure - regulation system that is a cut above the rest. This system uses a network of advanced sensors to continuously monitor the engine load, ambient temperature, and hydraulic oil temperature. Based on this real - time data, the system can instantaneously adjust the hydraulic pressure to meet the exact cooling demands of the excavator. When the engine is under heavy load, such as during large - scale earth - moving operations or when digging through tough rock formations, the system automatically boosts the hydraulic pressure, driving the fan to rotate at a higher speed for enhanced cooling. Conversely, during light - duty operations or idle periods, 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 leads to a 20% reduction in energy consumption compared to traditional fan pumps.
Whisper - Quiet and Vibration - Free Operation
In addition to its outstanding cooling performance, the 31QB - 30130 is engineered for quiet and smooth operation. The internal components are precision - balanced using state - of - the - art technology, and the fan blades are designed with advanced aerodynamics in mind. In a residential construction project near a hospital, the noise level of the excavator's cooling system was reduced by a remarkable 40% after installing the 31QB - 30130. This not only creates a more comfortable working environment for the operator but also minimizes 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 30%.
Robust Construction: Built to Endure
Premium - Grade Materials for Maximum Durability
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 exceptional resistance to impacts, corrosion, and the high - pressure hydraulic forces that are typical in construction machinery. The internal gears are crafted from hardened steel with a Rockwell hardness of HRC 65, ensuring smooth operation even under the most demanding 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 a typhoon - prone area, the 31QB - 30130 has been operating flawlessly for over three years, with no signs of degradation or failure.
Stringent 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 comprehensive hydraulic performance tests, long - term pressure - endurance tests, and vibration - resistance tests. In the hydraulic performance tests, the pump's flow rate, pressure output, and efficiency are measured with extreme precision under a wide range of operating conditions. The pressure - endurance tests subject the pump to continuous high - pressure operation for over 1500 hours to ensure its long - term reliability. The vibration - resistance tests expose the pump to a diverse 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 Peace of Mind
We have complete faith 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 around the clock to provide prompt technical support.
