YCB Series Circular Arc Gear Pump

Product Name: YCB Series Circular Arc Gear Pump

Product Overview:The YCB Series Circular Arc Gear Pump is a high-efficiency, energy-saving rotary positive displacement pump designed as a superior upgrade to traditional involute gear pumps. Engineered for general industrial applications, it excels in transferring lubricating oils and liquids with similar properties. Thanks to its advanced gear geometry and robust construction, the YCB series is widely adopted in petroleum, chemical, marine, and machinery industries for oil transmission, fuel supply, and hydraulic drive systems.

Key Features & Technical Advantages:

• Advanced Circular Arc Gear Profile: The core of the YCB pump features gears manufactured with a double-arc sine curve profile. Unlike traditional involute gears, this design eliminates relative sliding between tooth surfaces during meshing. This breakthrough technology ensures zero tooth wear, absolutely smooth operation, no liquid trapping, and significantly lower noise levels.

• Stable Flow with Minimal Pulsation: The unique gear engagement provides a continuous and steady flow with extremely low pressure pulsation. This ensures stable system performance and reduces vibration in pipelines, making it highly reliable for precision fluid transfer.

• Built-in Overload Protection: The pump is equipped with a highly reliable safety (relief) valve as standard. It automatically activates to protect the pump and pipeline system from overpressure caused by blockages or accidental valve closures. The full reflux pressure is typically set at 1.5 times the rated discharge pressure.

• Long Service Life & High Efficiency: Due to the wear-free meshing action and optimized hydraulic design, the YCB pump offers exceptional volumetric efficiency and a prolonged operational lifespan. All internal rotating parts are automatically lubricated by the conveyed medium, simplifying maintenance.

• Flexible Sealing & Configuration: Available with either high-performance mechanical seals or packing seals to suit different temperature and leakage prevention requirements. The pump can also be configured with standard or explosion-proof motors based on specific working conditions.

Technical Specifications:

• Flow Rate: 0.6 - 80 m³/h (depending on the specific model)

• Working Pressure: 0.6 MPa (standard); customizable up to 2.5 MPa

• Temperature Limit: Standard models up to 80℃; high-temperature variants available up to 200℃

• Viscosity Range: 5 - 1500 cSt (mm²/s)

• Material: Cast Iron / Carbon Steel (Stainless steel variants available upon request)

• Sealing Options: Mechanical Seal or Packing Seal

Typical Applications:

• Petroleum & Oil Transmission: Ideal for use as transfer pumps or booster pumps in oil depots, docks, and pipeline systems for crude oil, diesel, and heavy oil.

• Industrial Lubrication: Widely used as a reliable lubricating oil pump for large-scale mechanical equipment, compressors, and hydraulic systems.

• Fuel Supply Systems: Perfect for the transfer, pressurization, and injection of fuel oil in industrial burners, boilers, and marine engines.

• General Machinery: Suitable for various industrial sectors requiring the stable transfer of non-corrosive, lubricating liquids free of solid particles and fibers.
