CB-B Series Gear Oil Pump | CB-B2.5, CB-B10, CB-B63, CB-B80 | High Efficiency Transfer Pump

CB-B Series High-Efficiency Small Flow Hydraulic Gear Transfer Pumps

Product Overview: The CB-B Series is an industry-standard “workhorse” for lubrication and low-pressure transmission systems, engineered for environments requiring stable flow and maximum reliability. This selection features core specifications ranging from micro-flow to mid-range capacities, including CB-B2.5, CB-B10, and higher-flow models CB-B63 and CB-B80. Designed with a simplified no-side-plate architecture, these pumps offer elite self-priming capabilities and superior tolerance to oil contamination. They are the premier choice for metal-cutting machine tools, textile machinery, hydraulic station circulation, and various light fuel oil transfer systems.

Key Technical Advantages:

• Superior Self-Priming: Optimized gear meshing chambers ensure rapid vacuum buildup even at low RPMs, facilitating a highly efficient and smooth suction process.

• High-Reliability Architecture: The streamlined mechanical design minimizes potential failure points and maintenance needs, ensuring continuous operation in harsh industrial environments.

• High-Efficiency Transfer: Models like the CB-B80 feature optimized internal flow passages to reduce friction power loss, maintaining high volumetric efficiency at pressures up to 2.5 MPa.

• Quiet & Smooth Performance: Precision-ground gear sets significantly reduce hydraulic ripples and mechanical vibration, helping to maintain machine tool accuracy.

• Excellent Interchangeability: Standardized square or rectangular flange mountings allow for seamless replacement of original lubrication pumps in legacy machinery.
