CB-B Series Gear Oil Pump | CB-B2.5, CB-B6, CB-B16, CB-B63, CB-B125 | Low-pressure Hydraulic Pump

CB-B Series Industrial Low-Pressure Hydraulic Gear Oil Pumps

Product Overview: The CB-B Series is the most widely utilized foundational power core in the fields of industrial hydraulics and lubrication. This comprehensive selection features the full displacement matrix, ranging from compact models CB-B2.5, CB-B4, CB-B6, CB-B10, and CB-B16 to high-flow configurations CB-B63 and CB-B125. Specifically engineered for hydraulic systems with output pressures below 2.5 MPa, these pumps utilize a high-precision, no-side-plate structure for elite self-priming and wear resistance. They are the premier choice for lubrication systems in lathes, milling machines, and grinders, as well as light fuel oil transfer equipment.

Key Technical Advantages:

• Rugged & Minimalist Design: Utilizing a classic no-side-plate architecture, the internal structure is exceptionally streamlined, drastically reducing mechanical failure rates and maintenance costs.

• Superior Self-Priming: Optimized gear meshing chambers ensure rapid vacuum buildup even at low-speed starts, facilitating highly efficient oil suction.

• High-Reliability Lubrication: Internal bearings are self-lubricating, making the pumps ideal for long-term continuous operation within oil temperatures of 40°C – 70°C.

• Quiet & Smooth Performance: Precision-ground gear sets effectively minimize pressure ripples and mechanical noise, ensuring the operational stability of machine tool hydraulics.

• Versatile Mounting Fitment: Standard rectangular/square flange and keyed shaft connections allow for seamless replacement of original pumps in various legacy machinery.
