CBGTF2 External Meshing Gear Oil Pump
1. Product Overview
CBGTF2 is a compact high-pressure external hydraulic gear pump, optimized for mobile machinery and compact installation hydraulic system. It adopts high-strength cast iron pump body and precision ground gear components, with F2 grade pressure design. This hydraulic gear pump features small outline dimension, stable pressure output and outstanding anti-contamination performance. It is widely used as main oil supply and pilot power unit for mini loaders, sanitation vehicles, agricultural machinery, forklifts and small hydraulic power packs. With standardized installation dimensions, it can directly replace original equipment pumps for aftermarket replacement.
Model Explanation
CBGTF2: CBGT series heavy duty gear pump, F2 stands for pressure grade and flange connection form.

3. Working Principle
The driving shaft drives a pair of external meshing gears to rotate. Negative pressure is generated in the suction chamber, absorbing hydraulic oil from the tank. The gear teeth carry oil to the pressure side and deliver pressurized fluid to each branch of the hydraulic system. The floating side plates automatically compensate axial wear clearance caused by long-time operation, minimize internal leakage, and keep the hydraulic gear pump working efficiently under continuous working conditions.
4. Core Advantages
1. Compact integrated structure, small volume, suitable for limited installation space.
2. Reinforced gear and side plate structure, strong resistance to pressure impact.
3. Floating side plate design effectively reduces internal leakage and ensures long-term stable efficiency.
4. Optimized gear profile realizes low noise and low flow pulsation.
5. Good anti-pollution property, adapts to dusty outdoor working environment.
6. Standard flange and oil port position, plug-and-play without modifying pipelines.
5. Application Range
This gear pump is extensively applied in the hydraulic system of compact loaders, road sweepers, garbage trucks, harvesters, industrial forklifts and small hydraulic stations, providing power for main working circuit and auxiliary steering circuit.
6. Common Faults & Replacement Suggestion
Replace the complete pump assembly when these problems occur: insufficient system pressure, slow movement of hydraulic components, oil leakage at shaft seal and mating surface, abnormal grinding noise inside pump body.
