CAT 3G6846 Variable Vane Hydraulic Pump Group 45VQ Series High Pressure Piston For CAT Crawler Flat Shovel
CAT 3G6846 Variable Vane Hydraulic Pump Group 45VQ Series High Pressure Piston For CAT Crawler Flat Shovel
The high-pressure power core of Carter's crawler flat shovel
In the heavy-duty operations of CAT crawler flat shovels-such as earthmoving, ore loading, and site leveling-stable and high-pressure hydraulic power is the key to ensuring efficient equipment operation. The CAT 3G6846 Variable Vane Hydraulic Pump Group is specially designed for this scenario, serving as the "power heart" that drives the shovel's lifting, lowering, and dumping actions. Equipped with a high-performance high pressure piston, it can stably output hydraulic energy under high load conditions, ensuring that the crawler flat shovel maintains strong working capacity even in harsh environments like mines and construction sites. The cat 3g6846 integrates variable vane technology and high-pressure resistance, making it a reliable choice for CAT crawler flat shovels.
Core advantage: Balancing high-voltage output and adaptability to working conditions
The cat 3g6846 pump stands out in crawler flat shovel applications with its ability to deliver high-pressure output while adapting to variable working conditions. Its high pressure piston is made of hardened alloy steel through precision forging, which can withstand continuous working pressures of up to 250 bar and peak pressures of 300 bar-easily meeting the high-pressure demand when the shovel lifts heavy materials (such as large rocks or bulk ore). As a variable vane pump, the cat 3g6846 can automatically adjust the displacement according to the load: when the shovel is in no-load or light-load state, it reduces the displacement to save energy; when heavy load is required, it increases the displacement to ensure sufficient power.
Another key advantage of the 3g6846 pump is its strong environmental adaptability. The pump body is treated with anti-corrosion and anti-wear technology, and the high pressure piston is coated with a wear-resistant layer, which can resist the erosion of dust, moisture, and hydraulic oil impurities. This allows the cat 3g6846 pump to operate stably in the dusty and vibrating working environment of crawler flat shovels, with a service life of more than 12,000 hours under continuous operation.
Technical features: Tailor-made for crawler-type flat shovel operations
- High-Pressure Stability: The cat 3g6846 uses a precision-machined high pressure piston and matching cylinder block, which minimizes internal leakage and ensures that the output pressure fluctuation is within ±2%-critical for the stable operation of the shovel's lifting mechanism.
- Variable Displacement Efficiency: The 3g6846 pump adopts variable vane technology, which can adjust the flow output in real time according to the working conditions of the crawler flat shovel. For example, when the shovel is moving, it reduces the flow to save fuel; when shoveling materials, it increases the flow to provide strong power.
- Easy Integration with CAT Systems: The cat 3g6846 pump is designed with CAT's standard interface, which can be seamlessly connected to the hydraulic system of CAT crawler flat shovels without additional modification, reducing installation difficulty and time.
- Quick Maintenance: The pump adopts a modular design. If the high pressure piston or other core components are worn, they can be replaced independently, and the maintenance process is simplified, minimizing the downtime of the crawler flat shovel.
