SDYB High Pressure Gear Pump | SDYB56.7L483 | SDYB56.7L328

LIC Hydraulic offers the SDYA & SDYB Series, a premier range of high-pressure aluminum gear pumps designed for the most demanding mobile and industrial environments. Models like SDYB56.7L483 and SDYB56.7L328 are recognized for their exceptional power-to-weight ratio and volumetric efficiency. By utilizing advanced axial pressure compensation plates, these pumps maintain a steady flow rate even under peak pressures of $25\text{ MPa}$ ($3600\text{ PSI}$), ensuring reliable performance for steering and auxiliary hydraulic circuits.

Technical Features

• High-Tensile Aluminum Housing: Engineered for thermal stability and reduced system weight, allowing for higher efficiency and easier installation in mobile applications.

• Pressure-Balanced Side Plates: Automatically adjust internal clearances to compensate for wear and thermal expansion, maximizing pump life.

• Versatile Mounting Options: Standardized shaft and flange configurations (e.g., 483/328 specs) allow for seamless integration with leading European and American machinery.

• Low Noise Operation: Precision-ground gears significantly reduce fluid-borne noise and vibration, ideal for indoor industrial use.

Expert Maintenance Tips

• Direction of Rotation: SDYB pumps are rotation-specific. Operating a “Left-hand” (L) pump in a clockwise direction will instantly blow the shaft seal and cause internal damage.

• Inlet Filtration: Gear pumps are sensitive to large particles. Ensure a suction strainer of at least $100\text{ mesh}$ is used to protect the precision-machined aluminum housing.

• Oil Compatibility: Use premium anti-wear hydraulic oil (ISO VG 46/68). Maintaining oil cleanliness at ISO 4406 19/17/14 will prevent the “scoring” of the side plates and extend the pump’s service life.
