Hi/Low Gear Pumps Gear Pumps
The Hi/Low 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 a 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 reduces the power consumption.
