Product details
CBQ-*5 External Gear Pump
1. Product Overview
CBQ-*5 external gear pump is a fixed displacement hydraulic gear pump widely used in mobile machinery hydraulic system. It adopts high-strength aluminum alloy housing, equipped with axial clearance automatic compensation mechanism and radial pressure balance structure. This hydraulic gear pump maintains high volumetric efficiency under long-hour continuous operation.
Multiple options are available for shaft connection, oil port form, mounting flange and rotation direction. Featuring compact structure, low noise, stable output flow and strong anti-pollution performance, it serves as an ideal power component for engineering machinery, sanitation vehicles, forklifts and agricultural machinery.

3. Working Principle
Driven by engine or motor, the paired external gears rotate inside the pump cavity. Vacuum forms at the suction side to draw hydraulic oil, and oil is pressurized and delivered to the hydraulic system from the discharge side.
The floating pressure compensation plate automatically compensates axial wear clearance, effectively reducing internal leakage. Radial balance structure lowers gear radial force, extending service life and ensuring stable flow output under varying load pressure.
4. Core Advantages
1. Axial clearance automatic compensation structure, stable high efficiency after long-term operation.
2. Lightweight aluminum alloy shell, compact layout, easy installation and maintenance.
3. Wide applicable speed range, still maintain good performance under low-speed working conditions.
4. Low vibration and low running noise, suitable for mobile construction machinery.
5. Rich configuration combinations: multiple displacement, flange, shaft and oil port options.
6. Strong adaptability to harsh working environment, excellent cost-effective aftermarket spare part.
5. Application Range
This hydraulic gear pump acts as power source of hydraulic system, extensively matched for forklifts, wheel loaders, small excavators, cranes, road rollers, sanitation trucks, agricultural machinery and various stationary hydraulic power units.
6. Common Faults & Replacement Suggestion
Typical failures: insufficient output flow, pressure failing to reach standard value, oil leakage at shaft seal, abnormal running noise.
Please check hydraulic oil cleanliness and filter element firstly. If serious wear occurs on gear, shaft sleeve and compensation plate, replace the complete gear pump assembly.
