Product Description
The GP-CBN-160 is a high-efficiency two-stage (Hi-Lo) hydraulic gear pump specifically engineered for applications requiring rapid cycle times and high splitting force, such as log splitters and hydraulic presses. By integrating two separate pump stages into a single housing, the GP-CBN-160 allows machinery to utilize a lower-horsepower engine while achieving maximum hydraulic performance, making it a gold standard for professional and DIY wood-processing equipment.

Applications
Wood Processing: The primary choice for log splitters, providing high-flow rapid movement for the wedge and high-pressure force for splitting tough wood.
Waste Management: Extensively used in trash compactors and vertical balers to achieve fast cycle times while maintaining high crushing pressure.
Industrial Pressing: Ideal for small-to-medium hydraulic press machines used in metal forming, bending, or assembly operations.
Construction & Demolition: Powers portable hydraulic tools such as concrete crushers and rebar cutters that require both speed and intense power.
Specialized Agricultural Equipment: Integrated into feed mixers and manure spreaders where varying load conditions require automatic torque adjustment.
GP-CBN-160 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 GP-CBN-160 is a high-performance, two-stage (Hi-Lo) external gear pump specifically designed for high-cycle-speed applications. It integrates two separate pumping sections—a large-volume low-pressure stage and a small-volume high-pressure stage—into a single body. This allows equipment like log splitters to achieve rapid movement and immense splitting force using relatively small engines.
GP-CBN-160: Provides high flow for rapid cylinder extension, then automatically switches to low flow/high pressure when it encounters resistance. This prevents engine stalling while maximizing force.
Single-Stage Pumps: Maintain a constant flow regardless of pressure, requiring significantly larger engines to achieve the same splitting force.
Note: The "160" designation typically refers to its 16 GPM (Gallons Per Minute) nominal flow rate.
3. What is the working pressure range of GP-CBN-160 pumps
These pumps are engineered for heavy-duty splitting and pressing tasks. They typically operate at a maximum rated pressure of 3000 PSI (207 bar). The internal unloading valve is usually factory-set to transition from the high-flow stage to the high-pressure stage between 400 and 900 PSI.
Yes, the GP-CBN-160 is a standardized 16 GPM two-stage pump that can replace equivalent models from brands like Haldex, Barnes, Dynamic, or Muncie. To ensure a proper fit, you must verify the shaft diameter (standard is 1/2" or 5/8"), mounting flange (standard 4-bolt), and the inlet/outlet port sizes.
High-quality mineral-based hydraulic oil: ISO VG32, VG46, or standard Dexron III ATF (common for log splitters in colder climates).
Anti-wear (AW) additives: Essential for maintaining the lubrication film during the high-pressure splitting phase.
Filtration: A 25-micron or better return line filter is critical to prevent debris from sticking in the internal check valves.
The GP-CBN-160 is designed for direct drive by gasoline engines, with an optimal operating speed of 3600 RPM. While it can function at lower speeds, maintaining the rated RPM ensures the internal unloading valve operates correctly and the pump provides the necessary GPM for efficient cycle times.

GP-CBN-160 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.
