3. General Technical Notes
-
Gear & Bearing: Equipped with 12-tooth precision integral gears and floating bushings, matched with DU anti-friction bearings for axial compensation. This design effectively reduces wear, ensures stable transmission under heavy load, and maintains low noise during long-term operation, while guaranteeing high volumetric efficiency across the entire pressure range.
-
Sealing: Adopts double mechanical shaft seal design to effectively prevent oil leakage under high pressure and high-speed working conditions. The standard configuration is nitrile rubber seals; Viton seals are optional for high-temperature working environments (-15°C to 110°C), meeting the needs of different application scenarios.
-
Fluid & Temperature: Recommended hydraulic fluid is mineral hydraulic oil; the minimum operating fluid viscosity is 12 mm²/sec, and the optimal viscosity range is 17-65 mm²/sec. The standard operating temperature is -20°C to 80°C (with nitrile seals); it is recommended to maintain fluid cleanliness at ISO 4406 18/16/13 or better to extend the service life of the pump.
-
Installation & Customization: Flanges, shafts and ports are designed in line with major European, German and American standards (SAE, ISO, DIN), supporting straight key or spline shaft configurations for easy installation and replacement. Customization options include rear covers with built-in relief/sequence valves, bearing supports, bidirectional rotation, and multi-stage pump combinations to meet specific application needs.
