GVO  Excavator EC360b R485 DX420 suitable for 191-5611 hydraulic fan motor piston pump. High quality.

The  excavator fan motor, model 191-5611, is specifically designed for models such as the E330C and E325C. It is used to drive the engine cooling fan, ensuring that the equipment’s cooling system operates smoothly even under heavy loads.

   Precision adaptation for popular models: Designed specifically for  E330C, E325C, and other mid-to-large excavators. The mounting holes, shaft diameters, and interfaces perfectly match the original factory specifications, allowing for direct replacement without modification, ensuring seamless integration with the hydraulic system.

Highly efficient and stable driving performance: featuring a plunger-type structure, it provides significant output torque and stable rotational speed, enabling it to effectively drive large fan blades. This ensures that the engine remains continuously cooled under high-temperature conditions, preventing shutdowns or damage caused by overheating.

     Durability and vibration resistance design: The casing is made from high-strength cast iron or aluminum alloy. The internal bearings and seals have undergone reinforcement treatment, enabling them to withstand the intense vibrations and harsh operating conditions of construction machinery. This results in a longer lifespan and reduced costs associated with frequent replacements.

Function

- Provide power: convert the mechanical energy of the engine into hydraulic energy, provide power for the hydraulic system of the excavator, drive the hydraulic motor, hydraulic cylinder and other actuators to work, and realize the extension, rotation, excavation and other actions of the excavator arm.

- Stable flow: as a quantitative pump, it can output a relatively stable flow at a certain speed, ensure the stable supply of oil in the hydraulic system, and make the excavator's actions coherent and stable.

- Generate pressure: during the oil output process, a certain pressure can be generated to meet the pressure requirements of different working parts of the excavator under different working conditions, such as greater pressure is required when excavating hard soil.
