Applications
Applications
Forklift & Material Handling Equipment: A primary choice for counterbalance and warehouse forklifts, pallet trucks, and stackers, where the compact CBK‑F design integrates easily with narrow chassis to power lifting, tilting, and steering functions with consistent, low‑noise performance.
Compact Construction Machinery: Ideal for mini excavators, skid‑steer loaders, and aerial work platforms, providing reliable power for boom, bucket, and outrigger circuits under continuous high‑cycle operation.
Agricultural & Farm Equipment: Widely used in tractors, seeders, fertilizer spreaders, and small harvesters, where the pump’s contamination‑resistant design and wide temperature tolerance handle variable outdoor conditions and fluid quality common in field environments.
Small Hydraulic Power Units (HPUs): A preferred component for compact hydraulic power packs used in machine tools, workshop presses, and lifting equipment, offering high efficiency and low power consumption for intermittent or continuous duty cycles.
Specialized Mobile Vehicles: Commonly employed in sanitation trucks, small dump vehicles, and utility service trucks, powering tail‑lifts, hoists, and auxiliary hydraulic systems with the durability to withstand frequent start‑stop cycles and vibration.
Industrial Automation & Lifting Systems: Used in scissor lifts, dock levelers, and automated material transfer equipment, where the pump’s stable pressure output and modular configurations ensure smooth, controlled movement across all operating speeds.
Factory&FAQ
CBK‑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.
The CBK‑F is built for high‑pressure performance and compact applications where basic gear pumps may lack durability:
Lightweight High‑Strength Aluminum Housing: Compared to cast iron pumps, its aluminum construction offers a superior power‑to‑weight ratio, reducing installation load while maintaining structural rigidity to minimize internal deflection at high pressures.
Floating Bushing Design: Unlike fixed‑bearing pumps, it uses pressure‑balanced floating bushings that automatically compensate for wear, maintaining high volumetric efficiency over long service life and offering greater resistance to fluid contamination and thermal shock.
Flexible Modular Design: With multiple displacement options, port configurations, and rotation directions, it provides far greater installation flexibility for cramped chassis environments than standard single‑specification gear pumps.
The CBK‑F is a compact high‑pressure specialist. Depending on the specific displacement, the series typically handles:
Continuous (Rated) Pressure: Up to 20 MPa (200 bar / ~2,900 PSI).
Intermittent/Peak Pressure: Up to 25 MPa (250 bar / ~3,600 PSI).
This robust pressure rating makes the CBK‑F ideal for powering lifting cylinders, steering systems, and compact hydraulic circuits on forklifts, construction machinery, and agricultural equipment.
Yes, the CBK‑F is a high‑quality, cost‑effective alternative to other premium compact gear pumps. It is often used as a replacement or upgrade for:
Other Chinese‑made CB/CBN/CBF series gear pumps
Small‑capacity external gear pumps from international brands (where mounting dimensions are compatible)
To ensure a successful swap, verify the Mounting Flange (SAE or standard metric), Shaft Type (keyed/spline), Displacement (mL/r), and Rotation Direction (clockwise/counterclockwise) to match your existing system.
To protect the precision gears, floating bushings, and wear plates, the following is recommended:
Oil Type: Premium mineral‑based hydraulic fluids with strong Anti‑Wear (AW) additive packages (e.g., ISO VG46 anti‑wear hydraulic oil).
Viscosity: Standard ISO VG32 to VG68. The optimal operating range is 20 to 40 cSt, though it can handle cold starts up to 430 cSt (2,000 SUS).
Filtration: Cleanliness is vital for bushing lubrication. A minimum filtration of ISO 4406 18/16/13 is recommended to prevent abrasive particles from damaging the gear and bushing surfaces.
The CBK‑F series offers a wide operating speed range suitable for diverse applications:
Rated Speed: 1500–2000 r/min (depending on displacement).
Maximum Continuous Speed: Up to 3000–4000 r/min (for smaller displacements).
Minimum Operating Speed: ≥400 r/min, ensuring stable oil intake even at low engine speeds.
