BB-B cycloid gear oil pump

A compact, low-noise positive-displacement internal gear pump designed for reliable oil transfer in industrial hydraulic and lubrication systems. The BB-B cycloidal rotor (internal gear) design delivers smooth, pulse-free flow, strong self-priming capability and stable performance at high shaft speeds. Its straightforward construction simplifies installation and routine maintenance, making it suitable for continuous operation in equipment where quiet, consistent oil supply is required.

Key features

• Positive-displacement internal (cycloidal) rotor design for steady, non-pulsating flow
• Low acoustic signature and smooth oil transportation
• Self-priming capability for easier start-up and suction performance
• Capable of operation at higher shaft speeds for compact, high-power installations
• Simple construction for easier servicing and lower downtime
• Rated for use in hydraulic systems with working pressures up to 2.5 MPa

Typical applications

• Industrial hydraulic power units for manufacturing and processing equipment
• Power transmission circuits where positive-displacement oil feed is required
• Lubrication systems for pumps, gearboxes and rotating machinery
• Mobile hydraulic systems and other low-to-medium pressure fluid power installations

Selection and maintenance notes

• Use with appropriate hydraulic oils and viscosities recommended for internal-gear designs to maintain sealing and wear characteristics
• Ensure system pressure does not exceed recommended maximum (up to 2.5 MPa) and provide proper filtration to extend service life
• Routine inspection of drive coupling, seals and mounting hardware will help maintain quiet operation and consistent flow

For B2B procurement, the BB-B series is a practical choice where a compact, reliable, and low-noise positive-displacement oil pump is required for systems under 2.5 MPa.
