Description

Product Overview

The CBHST2 series gear pump, represented by the core model CBHST2100 SC, is an advanced energy-efficient hydraulic gear pump designed for heavy machinery applications. Manufactured with high-quality solid cast iron, this series adheres to ISO and UNI mounting dimensions, featuring both rear and side oil port designs to ensure long-term durability and high operational efficiency. It is a fixed-displacement external gear pump, delivering stable fluid output with each revolution, making it ideal for hydraulic systems requiring reliable performance.

Core Features

  • High Efficiency & Energy Saving: Adopting advanced gear meshing technology, the transmission efficiency is 3% higher than that of traditional hydraulic pumps, effectively reducing energy consumption during operation.
  • Stable & Reliable Performance: Under 40 hours of continuous rigorous testing, the working pressure fluctuation is controlled within an extremely narrow range. The internal cleanliness of the pump assembly is strictly limited to no more than 40 mg, ensuring stable operation.
  • Durable Construction: Made of high-strength alloy materials with precision machining technology, the pump exhibits excellent wear resistance. The external gear structure enhances structural rigidity, enabling it to withstand harsh working conditions.
  • Flexible Design: Supports bidirectional rotation and is equipped with protective covers for oil inlets and outlets to prevent contamination. The black exterior finish ensures corrosion resistance in various environments.
  • Wide Compatibility: Performance and accessories are fully compatible with major European and American brand products, reducing maintenance costs and facilitating replacement.
