Product Description
BB Series High-Efficiency Hydraulic Cycloidal Gear Pumps
Product Overview: The BB Series cycloidal gear pump is a compact, high-performance positive displacement pump engineered for a wide range of industrial hydraulic and lubrication systems. This range highlights core specifications including BB-B16, BB-B25Y, BB-B32Y, BB-B63Y, and BB-B100Y. The defining feature of the series is its internal cycloidal gerotor design, which utilizes a minimal tooth difference to deliver exceptionally low flow pulsation and ultra-quiet operation. With its superior self-priming capabilities, it is the definitive choice for forced lubrication in machine tools, textile machinery, and reduction gears, maintaining stable pressure even at low RPMs.
Key Technical Advantages:
Simplified Design & Reliability: Featuring only two moving parts (inner and outer rotors), the BB series minimizes mechanical wear and potential failure points, ensuring long-term operational stability.
Superior Self-Priming & Smooth Flow: The cycloidal meshing ensures continuous and smooth oil suction, preventing cavitation and system vibration while maintaining consistent delivery.
Ultra-Low Noise Profile: Significantly quieter than conventional external gear pumps, making it the preferred power source for indoor CNC machinery and precision lab equipment.
Wide Media Compatibility: Optimized for mineral-based hydraulic oils and lubricating fuel oils, capable of handling operating pressures from 2.5 MPa to 6.3 MPa.
Target Applications: CNC spindle lubrication, hydraulic charge pumps, cooling/filtration circulation systems, and gearbox forced-feed lubrication.
