Product Description
CBN‑G300 series gear pump is a high‑pressure external gear pump with compact structure, widely used in medium‑heavy‑load hydraulic systems. Adopting high‑precision gear machining and reinforced pump‑body design, it features stable flow output, low noise, high volumetric efficiency and strong anti‑pollution ability. Standardized mounting dimensions ensure good interchangeability, ideal for construction machinery, agricultural machinery and industrial hydraulic equipment.
High‑pressure Resistance
Rated pressure: 20MPa, maximum working pressure up to 25MPa, stable performance under long‑time heavy‑load operation.
Stable & Efficient Output
Precision‑matched gear pairs reduce flow pulsation, guaranteeing continuous and steady oil supply.
Compact & Easy Maintenance
Small overall size, light weight, standard flange and shaft‑end design for easy installation and replacement.
Low Noise & Long Service Life
Optimized gear tooth profile minimizes meshing impact; wear‑resistant materials extend service life greatly.
Strong Environmental Adaptability
Tolerant of impure hydraulic oil, suitable for complex working conditions like construction sites and farms.
Complete Displacement Range
Displacement covers 20–63ml/r, multiple specifications to meet different flow and power requirements.

Press machinery
CBN-G300 Series Gear Pump are manufactured in compliance with international standards, ensuring high performance and reliability:
ISO 9001: Certified for quality management systems.
CE Certification: Ensures compliance with European safety, health, and environmental protection standards.
RoHS Compliance: Ensures the pump does not contain hazardous materials.
Factory Testing: Every pump is rigorously tested for performance, pressure, and leak integrity before shipping.
The pump's flow is adjusted by changing the angle of an internal swash plate. As the swash plate angle changes, the stroke length of the pistons varies, which in turn changes the volume of fluid displaced per rotation, allowing the flow rate to adapt to the system's needs.
