MVW MFW
Xeriwell or Others
Eaton's MVW and MFW series hydraulic motors are designed for high-pressure, high-performance applications, offering reliability and efficiency in demanding environments.
MVW Series Hydraulic Motors:
The MVW series features variable displacement axial piston motors with a swashplate design, suitable for hydrostatic drives. These motors are engineered with large shaft bearings, providing full through-drive capability and extended service life. They are pressure-rated up to 350 bar, with a rated speed up to 1800 rpm, and offer a range of control options, including full overcenter capabilities. The MVW series can handle a wide range of fluids, including water-glycol mixtures. Available displacements range from 250 cc/rev to 750 cc/rev.
MFW Series Hydraulic Motors:
The MFW series comprises fixed displacement axial piston motors with a swashplate design, ideal for hydrostatic drives. These motors are also engineered with large shaft bearings for full through-drive capability and long service life. They share similar pressure and speed ratings as the MVW series, being pressure-rated up to 350 bar and capable of operating at speeds up to 1800 rpm. The MFW series accommodates a variety of fluids, including water-glycol mixtures, and is available in displacements from 250 cc/rev to 750 cc/rev.
Key Features:
1）High Pressure Rating: Both MVW and MFW series motors are designed to operate continuously at pressures up to 350 bar, ensuring robust performance in high-pressure applications.
2）Durable Construction: The incorporation of large shaft bearings enhances durability and supports full through-drive capabilities, extending the motors' operational lifespan.
3）Fluid Compatibility: These motors are compatible with a wide range of hydraulic fluids, including water-glycol mixtures, providing versatility across different operating conditions.
4）Control Flexibility: The MVW series offers variable displacement with full overcenter capabilities, allowing for precise control in various applications.
5）Efficient Operation: The swashplate design ensures efficient power transmission and smooth operation, contributing to overall system efficiency.
Eaton's MVW and MFW series hydraulic motors are well-suited for applications requiring reliable and efficient hydraulic power, such as pulp and paper processing, chemical pump drives, primary metals production, marine winches, and mixers.
