CBK Hi/low Gear Pumps

CBK Hi/low Gear Pumps

General Description



The CBK 2-stage gear pump consists of a big displacement, low pressure pump and a small displacement, high pressure pump, a check valve as well as an unloading valve. While working at the pressure lower than the unloading pressure, both big and small pumps output flow. When working at a higher pressure,only small pump outputs flow,which highly reduces the power consumption. The CBK hi/low pumps are widely used in the power units for trash compressors, machine tools and presses.
