High PressureDisplacement

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

High PressureDisplacement

The CBNA series (22&28 GPM)gear pumps are the same structure of small flow Hi/Lopumps. Mounting is 2 bolts flanges. When working at a high pressure, only small pumpsupplies volume, which highly reduces the power consumption. The CBNA pump is widelyused in log splitter, press, machine tools.
