It applies to delivering non-corrosive lubricating-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 hydraulicSystem,too.
Applacation Scope
 It can give performance as transferpump or booster pump in oil delivery system,and a fuel pump for delivery,pressurization and injectiion in fuel supply system.It can be also applied as hydraulic pump suplying hydraulic power in hydraulic system and in all industy 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 gears are adoped double circular teech shape,which makes the gears less wear on gear surface,stable revolution,low noise,long service life and high efficiency ,due to on sliding on the teeth during gear falling-in.This kind of pump has got rid of traditonal design and come into a new decade in designing and application.
The pump is designed with safety valve for protection against overload.The full return flow pressure is 1.5times higher than the rated exhaust pressure of the pump.It can be adjusted within the allowance of exhaust pressure range according to Circumstance .But please note the safety valve can't be applied as presusure-reducing valve for long time.You may install pressure-reducing valve separately on pipe-line if needed.
There are two kinds of axle-end seals,mechanical seal and packing seal ,which can be chosen according to the clients' requirement or application circumstance.
