Applications
Applications
Agricultural Machinery: A core component for tractors, harvesters, seeders, and fertilizer spreaders. The pump’s rugged construction handles fluid contamination and variable load shocks common in outdoor field environments, powering steering, lifting, and implement control systems.
Construction & Road Equipment: Widely used in excavators, loaders, small cranes, and road rollers. Its high-pressure capability and stable flow output support boom lifting, bucket operation, and compaction systems in demanding construction sites.
Material Handling & Logistics: Ideal for forklifts, pallet trucks, truck tail-lifts, and aerial work platforms. The compact design integrates easily with vehicle frames, delivering efficient power for lifting, tilting, and ramp operations in warehouses and logistics fleets.
Specialized Mobile Vehicles: Perfect for utility trucks, sanitation vehicles, and snow plows. The durable aluminum housing and wear-resistant components withstand frequent cycles and harsh conditions, powering refuse compaction, salt spreaders, and snow removal systems.
General Industrial Hydraulics: Suitable for machine tools, presses, and small hydraulic power units. The pump’s consistent efficiency and low noise make it a reliable choice for factory automation and light-to-medium industrial applications.
Factory&FAQ
CBN‑E/F pumps are typically packaged securely to prevent damage during transit. The packaging includes:
Protective Wrapping: To safeguard the pump from environmental damage.
Custom Crates: For larger, heavier pumps, ensuring safe handling.
Documentation: Includes installation, maintenance instructions, and warranty details.
Delivery time depends on the model, customizations, and location but typically ranges from 2 to 6 weeks from the order date.
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.
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.
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.
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.
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.

CBN‑E/F series pumps are manufactured in compliance with international standards, ensuring high performance and reliability:
ISO 9001: Certified for quality management systems.
CE Certification: Ensures compliance with European safety, health, and environmental protection standards.
RoHS Compliance: Ensures the pump does not contain hazardous materials.
Factory Testing: Every pump is rigorously tested for performance, pressure, and leak integrity before shipping.
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.
