It applies to delivering non-corrosive lubricating-lil or equivalent liquid without solid pareicles and fibres at temperature bilow 80℃ and with the viscosity of 5×10-6~1.5×10-3m2/S(5-1500cSt).
Applacation Scope
It can give performance as transferpump or booster pump in oil delivery system.It can be also applied as a fuel pump for dilivery system,pressurization and injection in fuel supply system and in all industry fields as lubricating pump.
Structure Features
 KCB series gear pumps are mainly composed of gears,axles pump body,pump,cap safety valve and axle-end seals etc.The heattreated gears have the advantage of higher hardness and intensity,and rotate with the axles inside the replaceable bearing sleeves.All of pump's parts can be lubricated by delivered medium when working.
The pump is properly designed with leakage and return chute,which lets the gears bear the least torque force and reduces load and wear on bearings bear the least torque force and reduces load and wear on bearings in order to raise pump's efficiency.
It is also designed with safty valve for protection against overload.The full return flow pressure of the safety valve is 1.5times higher than the rated exhaust pressure of the pump.It can be also adjusted within the allowance of exhaust pressure range according to circumstances .But please note the safty valve can't be applied as pressure-reducing valve for long time .You may install pressure-reducing valve separately on pipe-line if needed.
