Product Description

CBN-E/F Series Gear Pump  Overview

The CBN-E/F is a high-performance, fixed-displacement external gear pump engineered for compact hydraulic systems that demand reliable high-pressure output and long service life. Featuring a rugged yet lightweight construction, the CBN-E/F is specifically designed to deliver a high power-to-weight ratio, making it an ideal choice for direct mounting in agricultural machinery, construction equipment, forklifts, and mobile hydraulic systems where space is limited and performance is critical.

CBN-E

Features and Benefits

  • Rugged, Lightweight Alloy Housing Construction:
    The CBN-E/F is built with high-strength aluminum alloy bodies and covers, offering a superior combination of structural rigidity and light weight compared to cast iron alternatives. This design minimizes internal deflection under high-pressure duty cycles, ensuring stable performance while reducing overall system weight.
  • High-Efficiency Floating Bushing Design:
    Utilizing pressure-compensated floating bushings, the CBN-E/F automatically adjusts axial clearances during operation. This advanced design maintains high volumetric efficiency even at varying pressures, compensates for gear face wear, and protects the pump from premature failure in demanding use conditions.
  • Precision-Machined Gear Set:
    Equipped with high-precision helical or spur gears, the CBN-E/F delivers smooth, low-noise operation and consistent flow output. The precision-machined gear profile minimizes internal leakage, ensuring reliable power delivery across a wide range of operating speeds and temperatures.
  • Superior High-Pressure Capability:
    Despite its compact footprint, the CBN-E/F is engineered to handle continuous operating pressures of up to 20 MPa (2900 psi). Its heat-treated steel gears and precision components allow it to power hydraulic actuators and circuits with stable, reliable flow.
  • Modular Versatility and Installation Flexibility:
    The CBN-E/F series offers a versatile range of displacements (from 4 to 25 cc/rev) and supports standard SAE mounting and porting configurations. With multiple port orientation options (side, rear, top), it provides unmatched installation flexibility for cramped chassis environments and a wide variety of mobile applications.

CBN‑E/F Series Gear Pump  FAQ

1. What are CBN‑E/F series gear pumps

The CBN-E/F is a high-performance, fixed-displacement external gear pump designed for compact hydraulic systems requiring reliable high-pressure output and a high power-to-weight ratio. Featuring a lightweight yet robust aluminum alloy housing, it is widely used in agricultural machinery, construction equipment, forklifts, and mobile hydraulic applications where space is limited and efficiency is critical.

2. What makes the CBN‑E/F series pumps different from standard gear pumps

The CBN-E/F stands out from basic gear pumps in three key ways:
  • Pressure-Compensated Floating Bushings: Unlike fixed-clearance pumps, the CBN-E/F uses floating bushings that automatically adjust axial clearances to maintain volumetric efficiency, reduce wear, and extend service life under varying pressures.

  • Lightweight High-Strength Housing: The aluminum alloy construction offers significant weight savings over cast iron pumps, making it ideal for mobile equipment, while still providing excellent structural rigidity.

  • Modular Installation Flexibility: With multiple port orientations (side, rear, top) and standard SAE mounting configurations, the CBN-E/F adapts to cramped chassis environments better than many fixed-port pump designs.

3. What is the working pressure range of CBN‑E/F series pumps

The CBN-E/F series is a versatile high-pressure solution, with ratings depending on the model:

  • CBN-E Series:

    Continuous Pressure: Up to 16 MPa (2320 psi)

    Intermittent/Peak Pressure: Up to 20 MPa (2900 psi)

  • CBN-F Series:

    Continuous Pressure: Up to 20 MPa (2900 psi)

    Intermittent/Peak Pressure: Up to 25 MPa (3625 psi)

These ratings make the CBN-E/F suitable for powering lifting, steering, and compaction systems in light-to-medium duty mobile and industrial applications.

4. Can CBN‑E/F series pumps replace other brands

Yes, the CBN-E/F is a popular, cost-effective replacement or upgrade for many standard gear pumps, including:

  • Parker PGP Series

  • Nachi IPH Series

  • Vickers VGP20 Series

  • Other common aluminum-body external gear pumps

To ensure a successful swap, verify the Mounting Flange (SAE A/B), Shaft Type (keyed/spline), Displacement (cc/rev), and Port Orientation to match your existing system.

5. What hydraulic oil is suitable for CBN‑E/F series gear pumps

To protect the precision gears and floating bushings, the following is recommended:

  • Oil Type: Premium mineral-based anti-wear (AW) hydraulic fluids, compatible with standard industrial and mobile applications.

  • Viscosity: ISO VG32 to VG68. The optimal operating range is 20–30 cSt (100–150 SUS), though it can handle cold starts up to 430 cSt (2000 SUS).

  • Filtration: A minimum cleanliness level of ISO 4406 18/16/13 is recommended to prevent abrasive particles from damaging gear and bushing surfaces.

6. What is the typical speed range of CBN‑E/F series pumps

The standard operating range is:

  • Rated Speed: 2000 rpm

  • Maximum Speed: 3000 rpm (varies slightly by displacement)

Operating outside this range may reduce efficiency or shorten service life, so it is recommended to match the pump speed to your system’s design requirements.

FAQ

1.How does the variable displacement work?

The pump's flow is adjusted by changing the angle of an internal swash plate. As the swash plate angle changes, the stroke length of the pistons varies, which in turn changes the volume of fluid displaced per rotation, allowing the flow rate to adapt to the system's needs.
