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.
Rotation: CCW
Inlet Ports: 3/8 NPT Rear and 3/8 NPT Side
Sequence Setting: 200 to 800 psi; Preset at 600 psi
L: Distance from mounting face to rear cover
