CB-B Series Gear Oil Pump | CB-B32 CB-B63 CB-B125 CB-B160 | Hydraulic Pump

LIC Hydraulic provides the CB-B Series, a robust and reliable choice for low-to-medium pressure hydraulic applications. These external gear pumps, ranging from CB-B32 to CB-B160, are engineered with a simplified design that excels in longevity and ease of maintenance. Known for their “workhorse” reputation, CB-B pumps are widely used in machine tool lubrication, textile machinery, and oil transfer systems. Their ability to handle fluids with higher impurity tolerance makes them a top choice for environments where high-precision filtration is not always feasible.

Technical Highlights

• Simplified Design: The absence of side plates reduces internal complexity, making the pump highly resistant to mechanical wear and easy to service.

• Superior Self-Priming: Features an excellent suction capability, allowing for flexible mounting positions relative to the oil reservoir.

• High Volumetric Efficiency: Precision-machined gears ensure that models like CB-B100 and CB-B160 maintain consistent flow output at rated speeds.

• Broad Compatibility: Ideal for mineral-based oils and various industrial lubricants used in machine cooling and lubrication circuits.

Application Areas

• Machine Tools: Essential for grinding, milling, and lathe hydraulic control units.

• Lubrication Stations: Reliable circulation for gearboxes and industrial power units.

• Light Industry: Driving sequences in textile, printing, and packaging machinery.

Expert Maintenance Tips

• Avoid Dry Running: Before the first start-up, ensure the pump chamber is filled with oil. Dry friction can score the internal gears of the CB-B63 within seconds.

• Verify Rotation: CB-B pumps have a specific rotation direction (standard is Right-hand/Clockwise). Reversing rotation will result in zero pressure and potential seal failure.

• Filter Quality: While tolerant of some impurities, using a $40\text{–}80\text{ }\mu\text{m}$ suction filter will significantly extend the life of the pump housing and gear teeth.
