Swisher 11GPM Hydraulic 2 Stage Pump

The CBN gear pump consists of a big displacement, low pressure pump and a small displacement, high pressure pump, a check valve as well as a relief valve. When working at the pressure lower than the relief pressure, both big and small pump supply volume. When working at a high pressure, only small pump supplies volume, which highly reduces the power consumption. The CBN pump is widely used in log splitter, press, machine tools.
