Description

Parameter Description of SALAMI Gear Pump 3PE Series

1. Product Overview

The SALAMI 3PE series gear pumps are high-performance heavy-duty hydraulic gear pumps, specifically designed for severe industrial and mobile hydraulic applications. Adopting a robust aluminium alloy body with cast iron flanges and rear covers, the series is equipped with 12-tooth precision integral gears, floating bushings for axial compensation, and DU anti-friction bearings. This structural design ensures excellent volumetric efficiency, high mechanical efficiency, low noise operation, and long service life. Equipped with double mechanical shaft seals, the 3PE series features flanges, shafts and ports compatible with major European, German and American standards, supporting a wide displacement range and being widely applied in construction machinery, mining equipment, agricultural machinery and heavy-duty industrial hydraulic systems. All units undergo strict hydraulic testing after assembly to ensure consistent and reliable performance.

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.
Note: SALAMI reserves the right to change product specifications without prior notice. For further details, customized configurations, the latest technical updates or application-specific recommendations, please contact the SALAMI sales department or authorized distributors. Installation, commissioning and maintenance must comply with SALAMI official guidelines to ensure safe and reliable operation.
