CBN-F563 HCHC Hydraulic Gear Pump 63cc 25MPa

Product Overview

The CBN-F563 is a CBN-F5 Series fixed-displacement external gear pump associated with HCHC / Hefei Changyuan Hydraulic.

HCHC’s official product portfolio lists CBN-F5 among its hydraulic gear-pump products and identifies its broader CBN product family within its external-gear-pump portfolio.

Public technical documentation identifies the CBN-F5 displacement range and specifies 63 mL/rev for CBN-F563, together with a 20 MPa rated pressure, 25 MPa maximum pressure, 2500 rpm rated speed and 3000 rpm maximum speed.

The pump uses a conventional fixed-displacement external gear architecture, converting mechanical shaft rotation into hydraulic flow through positive-displacement gear engagement. The platform is suitable for mobile and industrial hydraulic systems where stable flow generation and straightforward mechanical construction are required.

HCHC’s official application information identifies hydraulic gear pumps across construction machinery, industrial vehicles, agricultural machinery, road machinery and industrial applications.

Our replacement version is developed around the original pump’s displacement, pressure class, rotation, mounting configuration, shaft and port requirements and undergoes 100% simulated operating-condition testing to validate flow, pressure, leakage and operating stability.

CBN-E3 / F3 / E4 / F4 / E5 Verification Note

HCHC’s official product portfolio confirms these CBN-family product names within its hydraulic gear-pump range, but the currently accessible official pages do not provide complete individual technical tables for CBN-E3, CBN-F3, CBN-E4, CBN-F4 and CBN-E5.

Therefore:

• CBN-F3 should not automatically inherit CBN-F5 pressure ratings.
• CBN-E3 should not have its displacement inferred from F3 or F5.
• CBN-F4 should not automatically inherit F5 specifications.
• CBN-E4 requires the complete model code.
• CBN-E5 requires its exact displacement and configuration.

This distinction is essential for an engineering-grade B2B product page.

Key Technical Advantages

1. 63 mL/rev Large Displacement

CBN-F563 has a theoretical displacement of 63 mL/rev.

At 2500 rpm:

63 × 2500 / 1000 = 157.5 L/min

At 3000 rpm:

63 × 3000 / 1000 = 189 L/min

These are theoretical displacement-flow calculations. Actual delivered flow depends on volumetric efficiency, pressure, oil temperature and internal leakage.

2. High-Pressure External Gear Architecture

The CBN-F5 data specifies 20 MPa rated pressure and 25 MPa maximum pressure, providing an appropriate pressure class for many mobile and industrial hydraulic systems.

3. Multiple Displacement Platform

CBN-F5 provides:

20 / 25 / 32 / 40 / 50 / 63 mL/rev

This allows machine designers to select pump displacement according to target flow and prime-mover speed. (poocca.com)

4. Mobile-Hydraulic Suitability

HCHC officially identifies construction machinery, industrial vehicles, agricultural machinery, road machinery and industrial hydraulic systems as application areas for its hydraulic products.

5. Configuration Flexibility

The CBN-F5 family is available in different shaft, port and mounting configurations. HCHC’s official portfolio also includes single, tandem and multiple-section gear pumps.

6. Straightforward Positive-Displacement Design

External gear pumps use a mechanically simple positive-displacement principle. The resulting architecture offers predictable flow behavior and relatively straightforward troubleshooting for mobile hydraulic equipment.

Expert Maintenance Tips

Verify the Complete CBN-F563 Configuration

CBN-F563 identifies the 63 mL/rev F5 configuration, but final replacement requires confirmation of the complete suffix, including:

• Mounting
• Shaft type
• Rotation
• Port configuration
• Port location

Public model listings include CBN-F563-BF*, CBN-F563-BFP and CBN-F563-BFH configurations.

Do Not Treat 25 MPa as Continuous Pressure

The published CBN-F5 data distinguishes:

20 MPa = Rated Pressure

25 MPa = Maximum Pressure

The 25 MPa value should therefore not be used as the continuous design pressure without verifying the exact configuration and operating duty cycle.

Control Pump Speed

The CBN-F563 series data specifies:

2500 rpm rated / 3000 rpm maximum

Actual system speed must also account for engine speed, transmission ratio, oil temperature and operating pressure.

Design the Suction Circuit Correctly

A 63 mL/rev pump can require substantial inlet flow at high speed. Suction-line diameter, inlet-filter pressure drop and reservoir level should therefore be checked against actual system flow.

Control Shaft Alignment

HCHC’s official service guidance specifies:

• Flexible coupling between the pump and prime mover
• Shaft misalignment ≤0.1 mm
• No radial load, axial load or bending moment on the pump shaft
• Slow shaft insertion during installation
• No hammering or forced assembly

Clean the Hydraulic Circuit During Replacement

When replacing a CBN-F563, inspect:

• Hydraulic oil
• Suction filter
• Return filter
• Reservoir
• Suction line
• Coupling

Metal particles from a failed pump can rapidly damage the replacement gear set.
