Product details

CBTD-F4 External Gear Pump

1. Product Overview

CBTD-F4 external gear pump is fixed displacement high-pressure external meshing hydraulic gear pump. It adopts floating axial clearance automatic compensation structure, which can effectively reduce internal leakage and keep high volumetric efficiency during long continuous operation.

Various options are available for drive shaft style, mounting flange, oil port layout and rotation direction. This gear pump can be used as interchangeable spare parts for mobile machinery and general hydraulic equipment maintenance.

Model Code Explanation

- CBTD: Series code of external meshing gear pump

- F4: Structure specification code, determining installation dimensions and pressure grade

2. Main Technical Parameters

Item Specification

Pump Type Fixed displacement external meshing hydraulic gear pump

Rated Working Pressure 20 MPa

Maximum Peak Pressure 25 MPa

Operating Speed Range 600 ~ 2800 rpm

Volumetric Efficiency ≥92% under rated working condition

Housing Material High-strength cast aluminum alloy

Shaft Form Flat key shaft; spline shaft optional

Oil Port Connection Thread connection

Applicable Fluid ISO VG46, VG68 anti-wear hydraulic oil

Operating Temperature -20℃ ~ +80℃

Standard Seals NBR; FKM high-temperature seals optional

3. Working Principle

The driving shaft drives a pair of meshing gears to rotate inside the pump cavity. Vacuum is formed on the suction side to inhale hydraulic oil. The gears carry hydraulic oil to the pressure side and deliver pressurized oil into the hydraulic circuit.

The floating compensation plate automatically compensates axial clearance caused by friction wear, limits internal leakage and guarantees stable performance in long-hour 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 noise.

4. Strong anti-pollution capacity, suitable for complex working conditions.

5. Rich installation configurations to satisfy various matching demands.

6. Cost-effective alternative spare part for original hydraulic gear pumps.

5. Application Range

As the power source of hydraulic system, this hydraulic gear pump is widely applied in forklifts, small loaders, road rollers, sanitation vehicles, agricultural machinery and general hydraulic power units.
