YCB oil circulation gear pump

Compact, positive-displacement circle-arc (YCB series) gear pump engineered for industrial lubrication, fuel transfer and hydraulic boosting. Designed to handle clean lubricating oils and oil-like liquids without solid particles or fibers, the pump supports a wide viscosity range (approx. 5–1500 cSt) and is suitable for continuous transfer, boosting and injection duties in oil and fuel systems as well as acting as a hydraulic pump in drive circuits.

Key features

• Suitable fluids: lubricating oils and similar clean liquids (no solid grains or fibers)
• Viscosity range: 5–1500 cSt
• Construction materials: cast iron or steel (recommended for oils up to 80°C); stainless steel versions for higher-temperature fluids (up to ~200°C), corrosive liquids and hygienic applications
• Low-flash-point option: stainless-steel pump fitted with bronze gears for volatile liquids (e.g., gasoline, benzene)
• Drive compatibility: compatible with standard electric motors and explosion-proof motors for hazardous environments
• Typical applications: industrial lubrication systems, oil boosting and injection in fuel systems, hydraulic drive systems

Benefits

• Robust gear design for steady, metered flow and reliable service in industrial settings
• Multiple material options enable selection for temperature, corrosion and safety requirements
• Simple, compact construction eases installation and maintenance

Recommended for OEMs, maintenance teams and fluid-handling engineers specifying reliable gear pumps for lubrication, fuel transfer and low-to-medium-viscosity hydraulic applications. For selection, supply the required flow rate, discharge pressure and fluid properties so the correct YCB model and material configuration can be selected (example model: YCB6-0.6).
