3. Technical Notes
-
Gear & Bearing: Equipped with 12-tooth precision-ground helical gears and floating bushings for axial compensation, matched with high-load DU anti-friction bearings to enhance load-bearing capacity and reduce wear.
-
This design effectively minimizes internal leakage, ensures stable power transmission under medium-to-high pressure, maintains low noise during long-term continuous operation, and guarantees high volumetric efficiency across the entire pressure and speed range.
-
Sealing: Adopts high-performance double mechanical shaft seal with carbon-graphite and ceramic mating faces, which can effectively prevent oil leakage under high pressure, high speed and harsh working conditions. The standard configuration is nitrile rubber seals (applicable temperature: -20°C to 85°C); Viton seals (-15°C to 110°C) are optional for high-temperature working environments, and PTFE seals are available for corrosive fluid scenarios, fully meeting diverse application needs.
-
Fluid & Temperature: Recommended hydraulic fluid is anti-wear mineral hydraulic oil (ISO VG 32-68); the minimum operating fluid viscosity is 10 mm²/sec, and the optimal viscosity range is 18-60 mm²/sec. It is recommended to maintain fluid cleanliness at ISO 4406 16/14/11 or better, and install a high-efficiency filter in the hydraulic system to extend the service life of the pump and the entire system.
-
Installation & Customization: Flanges, shafts and ports are designed in line with major international standards (SAE J518, ISO 6162, DIN 24340), supporting straight key, spline or tapered shaft configurations for easy installation and replacement with other brands. Customization options include rear covers with built-in relief valves, anti-cavitation valves, bearing supports, bidirectional rotation, and multi-stage pump combinations to meet specific industrial and mobile application requirements.
