2.1 Series Selection – CBT vs CBN: Matching the Pump to Your Machine

The most important selection decision is choosing between the CBT and CBN series. They are not interchangeable across all applications.

CBT Series – Engineering Machinery (Forklift, Loader, Excavator)

The CBT series uses a standard floating structure - the floating bushing automatically compensates for axial clearance as the pump wears, maintaining volumetric efficiency over the service life. The F-grade versions (CBT-F304, CBT-F306) deliver 20 MPa rated pressure and 25 MPa peak pressure, making them suitable for the high-pressure demands of forklift and loader hydraulic systems. The E-grade versions (CBT-E310) provide 16 MPa rated pressure and 20 MPa peak, covering standard-duty engineering applications.

CBN Series – Agricultural Machinery (Tractor, Combine Harvester)

The CBN series is the enhanced compensation version with double-layer floating bushings designed specifically for the operating conditions of tractors and agricultural equipment. These pumps are widely used to power hydraulic steering systems and hydraulic lift systems on farm tractors, with models compatible with major agricultural brands including Kubota, Massey Ferguson, Landini, and Fiat.

Decision rule: If your machine is a forklift, loader, or excavator, choose CBT. If your machine is a tractor or agricultural equipment, choose CBN.

2.2 Pressure Grade Selection – E-Grade vs F-Grade

The CBT and CBN series are available in two pressure grades. Choosing the wrong grade can lead to premature failure or unnecessary cost.

Critical trade-off to understand: F-grade pumps deliver higher pressure but require more input power and generate more heat. If your system operates comfortably at 16 MPa, the E-grade pump is more cost-effective and runs cooler. If your system requires 20 MPa for sustained periods - such as a forklift lifting at rated capacity - the F-grade is necessary.

2.3 Displacement Selection – Match the Pump to Your Flow Requirement

The most common question we receive: "Which displacement do I need for my machine?"

Selection rule of thumb: Choose the smallest displacement that meets your flow requirement. This gives you the highest possible operating efficiency and the most compact package. If your system requires flow above 30 L/min, consider a larger displacement model or a double pump configuration.

2.4 Axial Clearance Automatic Compensation – Efficiency That Lasts

Both CBT and CBN series pumps use floating bushings that automatically compensate for axial clearance as the pump wears. This is not a static seal - it is a dynamic compensation mechanism that maintains the gap between the gear faces and the bushing surfaces throughout the pump's service life.

What this means for your maintenance budget: Without compensation, gear pump efficiency drops as internal clearances increase with wear. With automatic compensation, volumetric efficiency is maintained ≥93% (CBT) and ≥91% (CBN) over extended operating periods. The pump delivers consistent flow from installation through to the end of its service life, reducing the need for premature replacement.

2.5 DU Self-Lubricating Bearings – Maintenance-Free Operation

The gear shafts are supported by DU self-lubricating bearings - a composite material that provides maintenance-free operation without the need for external lubrication. In dusty, muddy, or high-vibration environments - exactly the conditions found on construction sites and farm fields - DU bearings resist contamination ingress and continue to function reliably.

Practical benefit: No grease points to service, no bearing lubrication to schedule, no risk of lubricant washout during high-pressure washing. The pump operates reliably in the harshest conditions with minimal attention.

2.6 Single and Double Pump Configurations – One Platform, Multiple Circuits

Both series support single and double pump configurations. A double pump combines two independent pump sections on a shared drive shaft, allowing one pump to serve two separate hydraulic circuits - for example, steering and lift on a tractor, or main and auxiliary functions on a loader.

What this means for your installation: One mounting flange, one drive coupling, two independent hydraulic circuits. This simplifies system architecture, reduces leak points, and saves valuable installation space on compact machines.
