Description

The duplex pump integrates two independent gear pumps, providing hydraulic power with different flow rates and pressures simultaneously. This design enables efficient and stable operation in equipment with multiple hydraulic circuits, excelling in both low-speed precision work and high-speed, high-pressure applications.

Technical Parameters

  1. Displacement per revolution: 0.8 – 13.8 cm³/rev
  2. Direction of rotation: D (clockwise), S (counterclockwise)
  3. Minimum speed: 600 rpm
  4. Maximum speed: 2500 rpm
  5. Peak pressure: 160 – 230 bar

Application Industries

  1. Hydraulic systems: Ideal for multi-circuit systems, supplying independent power to various hydraulic components for multifunctional equipment.
  2. Construction machinery: Powers separate hydraulic devices (e.g., lifting arms, buckets, bulldozers) for simultaneous, efficient operations without circuit interference.
  3. Agricultural machinery: Drives multiple hydraulic devices (e.g., front and rear systems in tractors, harvesters) for versatile work such as shoveling and lifting.
  4. Construction equipment: Supports complex operations in tower cranes, cranes, and similar machinery requiring multiple hydraulic circuits.

Features

  1. High efficiency: Dual-pump design meets different flow and pressure needs at once, improving system response and overall hydraulic efficiency.
  2. Long life: High-quality materials and precise manufacturing ensure stable operation under high load and pressure for extended service life.
  3. Consistent performance at low speeds: Delivers smooth hydraulic flow for fine control in applications requiring low-speed precision (e.g., construction or agricultural equipment).
  4. Various port and shaft extension options: Multiple configurations available for easy compatibility with different hydraulic systems, ensuring flexible and convenient installation.
  5. No leakage shaft seal: Advanced sealing technology guarantees leak-free operation, reducing oil waste, environmental impact, and improving system safety.
