Product Description
CB-B Series Low-Pressure Hydraulic Gear Pumps for Machine Tools
Product Overview: The CB-B Series stands as one of the most widely utilized basic power pumps in the industrial hydraulic sector, celebrated for its simple architecture, reliable performance, and exceptional cost-effectiveness. This comprehensive range spans from micro-flow 2.5cc (CB-B2.5) to high-capacity 100cc (CB-B100) models. Specifically engineered for low-pressure hydraulic systems, machine tool lubrication, cooling cycles, and fuel transfer, the CB-B series excels in handling standard hydraulic oils and lubricants. Its straightforward design makes it the premier choice for textile machinery, gearboxes, and centralized lubrication stations.
Key Technical Advantages:
Industrial-Grade Durability: Constructed with high-strength cast-iron bodies, offering a compact footprint and ease of maintenance for 24/7 continuous industrial duty.
Quiet-Running Performance: Optimized gear meshing parameters drastically reduce operational vibration and noise, ideal for noise-sensitive indoor workshop environments.
Excellent Self-Priming Capability: Features robust vacuum suction, maintaining stable oil flow even at low RPMs.
Versatile Media Compatibility: Suitable for hydraulic oils, turbine oils, and lubricants with viscosities ranging from 20 to 200 cSt, provided they are free of solid particles.
Superior Economy: Compared to high-pressure pumps, the CB-B series fulfills essential pressure requirements while significantly lowering procurement and long-term maintenance costs.
