Product Specification

GVO  234-4638 Hydraulic motor fan pump motor piston pump suitable for E330D, E336, E365C, E345 excavators/construction machinery parts.

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 design, it provides significant output torque and stable rotational speed, enabling effective driving of large fan blades. This ensures continuous cooling of the engine under high-temperature conditions, preventing shutdowns or damage caused by overheating.

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.

Strict factory testing: Each batch of products undergoes pressure testing, rotational speed testing, and life simulation testing to ensure stable output performance under high-pressure and high-speed conditions, with no leaks or unusual sounds.

Manufactured with high-quality materials: key components such as the plunger, flow distribution plate, and seals are made from wear-resistant alloys and high-performance rubber. They exhibit strong resistance to corrosion and aging, and are less likely to wear out or fail over time.

High-precision flow distribution mechanism: The clearance between the internal flow distribution plate and the plunger is controlled at the micrometer level, ensuring even distribution of hydraulic fluid, reducing internal leakage, and improving transmission efficiency.

Standardized process manufacturing: The threaded connections, mounting hole spacing, and electrical parameters all conform to the specifications of the original factory, thereby eliminating installation difficulties or poor contact caused by dimensional discrepancies.

   Precision shaft seal design: Utilizes a double lip oil seal or mechanical seal to effectively prevent hydraulic oil leakage and the intrusion of external impurities, thereby extending the lifespan of the motor.

     Stable output characteristics: The rated pressure, speed, and torque parameters are precisely calibrated to prevent fluctuations in speed or insufficient torque due to load variations, ensuring that the fan remains in optimal operating condition at all times.
