All - New Excavator Fan Pump 31QB - 30130 for Hyundai R385/R485/R520
In the cut - throat construction machinery market, where downtime can translate into substantial financial losses and project delays, having a reliable and high - performance Excavator Fan Pump is non - negotiable. We are excited to introduce the all - new 31QB - 30130, specifically engineered to meet the exacting demands of Hyundai R385, R485, and R520 excavators. This isn't just an ordinary fan pump; it's a technological marvel that combines precision engineering, advanced materials, and intelligent design to redefine cooling efficiency in heavy - duty construction equipment.
Seamless Compatibility: A Perfect Fit for Your Hyundai Excavators
The 31QB - 30130 is the result of painstaking research and development, with a laser - like focus on compatibility. Every aspect of its design, from the physical dimensions to the hydraulic connection points, has been meticulously crafted to match the original equipment specifications of Hyundai R385/R485/R520 models. The mounting brackets are designed to align perfectly with the existing holes on the excavator, while the hydraulic ports are sized and threaded to ensure a leak - free connection with the existing hoses. This seamless compatibility means that installation can be completed in a fraction of the time compared to generic or ill - fitting alternatives. In a recent case study, a construction company was able to install the 31QB - 30130 on their Hyundai R485 excavator in just 2 hours, reducing downtime and getting the machine back to work quickly.
Exceptional Performance: Cooling Redefined
High - Pressure and High - Flow Capability
At the heart of the 31QB - 30130 lies a state - of - the - art hydraulic system. The pump is capable of generating a maximum pressure of up to 3000 psi, which is 20% higher than the average fan pump in the market. This high - pressure output enables the fan to rotate at speeds of up to 3000 RPM, producing a powerful and continuous airflow of over 1000 cubic feet per minute. In a large - scale mining operation in the Australian outback, where temperatures can soar above 40°C and excavators are subjected to continuous heavy - duty use, the 31QB - 30130 was able to maintain the engine and hydraulic components at optimal operating temperatures. This not only prevented overheating - related breakdowns but also increased the overall productivity of the excavator by 15%, as it could operate for longer periods without the need for cooling - related shutdowns.
Intelligent Pressure Regulation
The 31QB - 30130 features an advanced intelligent pressure - regulation system. This system uses a combination of sensors and micro - controllers 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 increases during a large - scale earth - moving project, the system can increase the hydraulic pressure by up to 50% within seconds, driving the fan to rotate at a higher speed and providing enhanced cooling capacity. Conversely, when the load is reduced, the system can reduce the pressure, conserving energy and minimizing wear on the fan and pump components. This intelligent pressure - regulation system has been shown to reduce energy consumption by up to 10% compared to traditional fixed - pressure fan pumps.
Quiet and Smooth Operation
In addition to its outstanding cooling performance, the 31QB - 30130 is engineered for quiet and smooth operation. The internal components are precision - balanced to reduce vibrations, and the fan blades are designed using advanced aerodynamic principles to minimize noise. In a residential construction project in a densely populated area, the noise level of the excavator's cooling system was reduced by 30% after installing the 31QB - 30130. This not only improved the working environment for the operator but also reduced noise pollution for the surrounding community. The smooth operation also reduces the stress on the pump and other related components, extending their service life by up to 20%.
Durable Construction: Built to Last
High - Quality Materials
Constructed from top - grade 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, with a Rockwell hardness of HRC 60, 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 Florida, where the equipment is exposed to saltwater, high humidity, and intense sunlight, the 31QB - 30130 has been operating flawlessly for over 2 years, with no signs of corrosion or wear.
Rigorous Quality Control
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 1000 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 Peace of Mind
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.
