YHCB double circular arc gears pump

A high-efficiency double circular-arc gear pump designed for transferring non-corrosive liquids with a wide viscosity range. The YHCB double circular arc gear pump offers larger flow capacity than conventional gear pumps while maintaining compact size, low noise and low running speed. It is suitable for vehicle-mounted installations and stationary oil-handling equipment where reliable, continuous transfer of petroleum products and lubricants is required.

Key features

• Double circular-arc gear profile for increased flow and smooth operation
• Handles liquids with viscosity from 5 to 1500 cSt and temperatures up to 80°C
• Suitable for clean, particle-free, non-corrosive liquids (no solids)
• Low noise, compact footprint and low input speed requirements
• Strong self-priming capability and high overall efficiency
• Easy installation and maintenance (accessible pump casing and gears)
• Optional materials and safety features: bronze or stainless-steel gears; explosion-proof motor available

Typical applications

• Transfer of fuels and light petroleum products (extracted gasoline, kerosene, diesel)
• Machine lubricating oil circulation and dispensing
• Oil tanker vehicle retrofit and pump assemblies for transport vehicles
• Industrial lubrication, fuel transfer and batching systems where a compact, positive-displacement pump is required

Installation and operation notes

• Can be mounted on vehicles and driven directly via vehicle gearbox or suitable prime mover
• Not suitable for fluids containing abrasive solids or aggressive corrosives
• Choose stainless steel gears for more demanding cleanliness or compatibility requirements; select explosion-proof drive when required by site classification
• Routine inspection of gear clearances, seals and drive coupling improves service life and reliability

This pump is intended for industrial and transport-sector buyers looking for a compact, efficient gear pump for fuel and lubrication transfer tasks. For system integration, confirm viscosity, temperature and required flow/pressure to select the correct model size and materials.
