Gear Pump

Gear Pump

Gear Pump: Relevent model, KCB, 2CY, YCB, NYP, LYB, RCB, etc. We will elect the suitable model according your inquire.

KCB series gear pumps:


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).


In oil delivery system, it exploits the performance of transfer pump or booster pump.
In fuel supply system, it has the function of dilivery, pressurization and injection.
In all industry fields, it can be 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 heat-treated gears have the advantage of much high hardness and intensity, and they rotate together 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 bearing the least torque force, and which can reduces load and wear of bearings, so that pump's efficiency is improved.It is also designed with safty valve against overload. The pressure of safety valve's full return flow is 1.5 times higher than the rated exhaust's pressure. According to circumstances, the pressure of safety valve also can be adjusted within allowance range of exhaust pressure. Please be note the safty valve can't be applied as pressure-reducing valve for long time working. You may install pressure-reducing valve separately on pipe-line if needed.
