| 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. |

（1）Work principle
driving gera （outside rotor）with internal tooth drives the internal rotor and turns in same direction in the full closed pump body.The inlet from the outlet.When it turns,negative pressure formed at the suction port,the liquid inhaled and being take to thr outlet by rotor,then the liquid is wxpelled from th discharge port sa the gears mesh.The transpor-tation of liquid finished.
（2）Structure Feature
As figure I The pumps are mainly composed of internal rotor,outside rotor,shaft,pump casing,front cover,seal,bearing etc.
The pump"seal adopts packing seal or mechanical seal.When the delivered medium is high temperatur ,high visc or strong corrosion,packing seal should be adopted.
When the delivered medium is easy crystallinic ,we can designthe heat preservation jacket in pump casing and front cover in order to melt the medium with steam wen working.The pump can be also fitted with the safty valve.
The pump set is composed of the pump,motor and baseplate.
The driving way is belt wheel driving or coupling driwing.
