Marine KCB Series Gear Pump
1. Application
It applies to delivering non – corrosive lubricating – oil or equivalent liquid without solid particles and fibers at temperature below 300°C and with the viscosity of 5×10⁻⁶～1.5×10⁻³m²/s (5 – 1500cSt). Reducing the speed, the pump can deliver the liquid that the viscosity can be up to 5×10⁶cSt.
2. Application Scope
It can give perfect performance as transfer pump or booster pump in oil delivery system. It can also be applied as fuel pump for delivery system, pressurization and injection in fuel supply system and in all industry fields as lubricating pump.
3. Structure Features
KCB series gear pumps are mainly composed of gears, axles, pump body, pump cover, safety valve and axle – end seals etc. (Special requirement: magnetic force drive and zero – leakage structure can be selected). The housed 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 channel, which lets the gears bear the least torque force and reduces load and wear on bearings to raise pump’s efficiency.
It is also designed with safety valve for protection against overloading. The full return flow pressure of the safety valve is 1.5 times higher than the rated exhaust pressure of the pump. It can also be 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 a pressure – reducing valve separately on pipe – line if needed. The direction of rotation is clockwise viewed from coupling end.
