Marine electric gear pump KCB (2CY) Series
1. General
KCB series Marine electric gear pumps are mainly composed of gears, shaft, pump body, safety valve, shaft end sealing device. The gear is processed with high hardness and toughness, and the shaft is installed on replaceable bearing sleeves. The internal parts are lubricated by the delivered medium during 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. It is also designed with safety valve for protection against overload. The full return flow pressure of the safety valve is 1.5 times 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.
