Pump Specifications

  2CY series gear pumps mainly consist of gears, shafts, pump bodies, pump covers, bearing bushes, and shaft end seals. The gears and shafts are strictly heat-treated, have high hardness and wear resistance and are mounted in the shaft sleeves together with the shaft. All moving parts in the pump are lubricated with the medium they convey.

   The four bearing sleeves in the pump are floatingly installed in the pump body, and the gap surface of the broken end surface is automatically adjusted according to the working pressure. Therefore, the pressure of the pump is stable, the output flow pulsation is small, and the volumetric efficiency is high.

Technical Data

Structure Features 

    2CY series gear pump are mainly composed of gears, axles, pump cover, safety valve and axle-end seals etc. The heat-treatment gears have the advantage of higher hardness and intensity, and rotate with the axles inside the replaceable bearing sleeves. All of pumps’ 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 in order to raise pumps’ efficiency.

It is also designed with safety valve for protection against overload. The full return flow pressure of the safety valve is 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 safety valve can't be applied as pressure reducing valve for long time. You may install pressure reducing valve separately on pipe-line if needed.

The direction of rotation is clockwise viewed from coupling end.

Application Scope

1.  It can give performance as transfer pump or booster in oil deliver system.

2.  It can be also applied as fuel pump for delivery system, pressurization and injection in fuel supply system.

3.  In all industry fields it can be as lubricating pump.
