Application
It applies to delivering non-corrosive luricating-oil or equivalent liquid without solid particles and fibres at temperature below 80℃and with the viscosity of 5×10-6~1.5×10-3m2/S(5-1500cSt).It applies to hydraulic system,too.
Applacation Scope
It can give performance as transferpump or booster pump in oil delivery system,and a fuel pump for delivery,pressurization and injection in fuel supply system .It can be also applied as hydraulic pump supplying hydraulic power in hydraulic system and in all industry fields as lubricating pump.

Structure Features
YCB series gear pumps are mainly composed of gears,axles,pump body ,pump cap,bearing sleeves and axle-end seals,etc.The nitriding-treated gears have the advantage of higher hardness and wear property,and they rotate with the axles inside the replaceable bearing sleeves.All of pump's parts can be lubricated by delivered medium when working.
Four bearing sleeves are installed suspended in pump body and can be automtically adjusted with facing gaps clearance complying with pressure change,therefore,it results in stable pump pressure,little discharge ,flow pulsation and higher volume efficiency .
