CBWKA-F3 External Gear Pump
1. Product Overview
CBWKA-F3 external gear pump is a fixed displacement external meshing hydraulic gear pump. As an important power component of the hydraulic system, it adopts floating axial clearance compensation structure to minimize internal leakage and maintain stable volumetric efficiency during continuous operation.
Multiple installation configurations are optional, including drive shaft type, mounting flange, oil port orientation and rotation direction. This hydraulic gear pump features compact layout, reliable performance and strong universality. It can serve as interchangeable aftermarket spare parts for engineering machinery, mobile equipment and stationary hydraulic power units.

3. Working Principle
The driving shaft drives a pair of meshing gears to rotate inside the pump cavity. Vacuum generates on the suction side to draw hydraulic oil, and the gears convey oil to the pressure side. Pressurized hydraulic oil is delivered to the hydraulic system.
The floating compensation plate automatically compensates axial clearance caused by friction wear. It effectively restrains internal leakage and keeps stable working efficiency under long-time continuous operation.
4. Core Advantages
1. Axial automatic clearance compensation design, low internal leakage and stable volumetric efficiency.
2. Lightweight aluminum alloy pump housing, compact structure, easy installation and maintenance.
3. Smooth operation, low vibration and low running noise.
4. Good anti-pollution performance, adaptable to various complex working conditions.
5. Standard mounting dimensions, convenient matching and replacement.
6. High cost performance, ideal replacement spare part for original gear pumps.
5. Application Range
This hydraulic gear pump provides power source for the hydraulic system, widely used in forklifts, small loaders, sanitation vehicles, agricultural machinery, general hydraulic power packs and light industrial machinery.
6. Common Faults & Replacement Suggestion
Typical failures: Insufficient output flow, unable to reach rated pressure, oil leakage at shaft seal, abnormal running noise.
First check hydraulic oil cleanliness and filter element status. Replace the complete gear pump assembly if gears, shaft sleeves and compensation plates suffer serious wear.
